3D interconnection by FIB assisted Pt deposition and electroless nickel deposition on the sides and edges of an I-Seed
(2006)
Razeeb, Kafil M.; Nagle, Lorraine C.; Barton, John; Tassie, Paul; O'Flynn, Brendan; Rohan, James F.; Ó Mathúna, S. Cian
Abstract:
This paper reports on the development of a 3D interconnection process leading to the successful assembly of a five-layer 3-D 1mm cube module. This proof of concept module demonstrates the capability for successful integration and interconnection of commercial off the shelf components to fabricate functional modules in 1mm cube dimensions. It also demonstrates that use of established volume scale technologies like Flip-chip, dicing and patterning techniques are viable for fabricating these 1mm modules. The demonstrator consists of LED's bonded to the six sides of the 1mm cube, interconnected and powered up. The work will particularly report on two different processes to fabricate the interconnection pattern using direct Focused Ion Beam (FIB) assisted Pt deposition and electroless metal deposition, which again patterned by FIB. Uniform thickness of the deposit and excellent coverage on all six sides is achieved by electroless nickel deposition. Voltage current characterisation o...

3D ranging and tracking using lensless smart sensors
(2017)
Abraham, Lizy; Urru, Andrea; Wilk, Mariusz P.; Tedesco, Salvatore; O'Flynn, Brendan
Abstract:
Target tracking has a wide range of applications in Internet of Things (IoT), such as smart city sensors, indoor tracking, and gesture recognition. Several studies have been conducted in this area. Most of the published works either use vision sensors or inertial sensors for motion analysis and gesture recognition [1, 2]. Recent works use a combination of depth sensors and inertial sensors for 3D ranging and tracking [3, 4]. This often requires complex hardware and the use of complex embedded algorithms. Stereo cameras or Kinect depth sensors used for high precision ranging are instead expensive and not easy to use. The aim of this work is to track in 3D a hand fitted with a series of precisely positioned IR LEDs using a novel Lensless Smart Sensor (LSS) developed by Rambus, Inc. [5, 6]. In the adopted device, the lens used in conventional cameras is replaced by low-cost ultra-miniaturized diffraction optics attached directly to the image sensor array. The unique diffraction pattern...

A 3D hand motion capture device with haptic feedback for virtual reality applications
(2018)
Torres-Sanchez, Javier; Tedesco, Salvatore; O'Flynn, Brendan
Abstract:
In this paper, the challenges associated with the design of new generation hand motion capture devices for Virtual Reality (VR) applications are described. The need for developing a hand motion capture device with tactile feedback that integrates all the sensors and actuators associated with VR, while meeting the latency requirements is introduced. A detailed description of functional and non-functional specifications is also given. Finally, a comparison study with commercially available technology is provided highlighting that the proposed device compares favorably not only in terms of functional parameters, such as connectivity, integration of sensors and actuators, and latency, but also in terms of non-functional parameters, e.g., no need to wash, ambidextrous features and modularity.

A 915 MHz wristwatch-integrated antenna for wireless health monitoring
(2020)
Kumar, Sanjeev; Buckley, John L.; Barton, John; Newberry, Robert; Dunlop, Gary; Rodencal, Matthew; Webster, Carlo; Pigeon, Melusine; Scanlon, William G.; O'Flynn, Brendan
Abstract:
A compact 915 MHz antenna integrated within a wristwatch wireless sensor device is presented. The antenna is a variant of a planar inverted-F antenna (PIFA) and uses a dual-resonator configuration. The results of simulation and measurement are shown to be in good agreement with the antenna exhibiting desirable impedance and radiation characteristics together with low Specific Absorption Rate (SAR) performance. The antenna is fabricated using a low cost flexible printed circuit and is fully integrated into the watch device. Measurements on the prototype antenna show a -10 dB impedance bandwidth of 30 MHz, a peak realized gain of -4.9 dBi and a peak radiation efficiency of 15.9% at 915 MHz. The antenna also has a low SAR value of 0.003 W/kg making it suitable for a wide range of wrist-worn wireless applications.

A bandwidth enhanced 915 MHz antenna for IoT wrist-watch applications
(2019)
Kumar, Sanjeev; Buckley, John; Barton, John; Newberry, Robert; Dunlop, Gary; Rodencal, Matthew; Webster, Carlo; O'Flynn, Brendan
Abstract:
This paper presents a 915 MHz planar inverted-F antenna (PIFA) topology for a wrist-worn wireless sensor application. When compared with a conventional PIFA implementation, an impedance bandwidth enhancement of more than 100% is achieved. The bandwidth enhancement is realized with inclusion of a parasitic element that excites an additional mode close to the resonant frequency. A parametric analysis of the key parameters is performed in order to optimize the antenna for 915 MHz operation. The measured results for the on-body prototype antenna show a -10 dB bandwidth of 26.4 MHz and a Peak Realized Gain of -0.57 dBi at 915 MHz. The simulated peak radiation efficiency of 46.8% is achieved. In addition, the design exhibits a low specific absorption rate (SAR) value of 0.004 W/kg.

Abstract:
This paper presents a novel, low-cost, battery-less Near-Field Communication (NFC) sensor transponder for museum artefact monitoring of Cultural Heritage objects. The proposed solution combines a unique combination of packaging materials and NFC technology to enable a low-cost preventive conservation solution that is practical to implement, something that is not possible at present. Cultural Heritage objects and artefacts are valuable objects housed by museums and are often stored in uncontrolled climatic conditions, which may lead to degradation of these objects. Preventive conservation is a new strategy that aims to avoid future degradation of these types of valuable objects. Recently, NFC sensor transponders have shown an increased use in food and pharmaceutical cold supply chains for monitoring, but these commercial solutions are expensive to implement and cannot be easily adapted for museum artefact monitoring. In this work, we present a battery-less, long shelf life, low-cost ...

Abstract:
Advanced sensory systems address a number of major obstacles towards the provision for cost effective and proactive rehabilitation. Many of these systems employ technologies such as high-speed video or motion capture to generate quantitative measurements. However these solutions are accompanied by some major limitations including extensive set-up and calibration, restriction to indoor use, high cost and time consuming data analysis. Additionally many do not quantify improvement in a rigorous manner for example gait analysis for 5 minutes as opposed to 24 hour ambulatory monitoring. This work addresses these limitations using low cost, wearable wireless inertial measurement as a mobile and minimal infrastructure alternative. In cooperation with healthcare professionals the goal is to design and implement a reconfigurable and intelligent movement capture system. A key component of this work is an extensive benchmark comparison with the 'gold standard' VICON motion capture sy...

Abstract:
The purpose of this study was to compare different approaches for the estimation of biomechanical loads in running. A neural network, a biomechanical model, and a two-mass model were tested on the same data set. The predictions of the neural network were highly accurate for all considered running speeds (average RMSE, 0.11 BW). The biomechanical model returned statistically similar results (p=0.113, 0.14 BW), but with increasing RMS errors at high running speeds. Finally, the two-mass model estimates were independent of running speed, but were the least accurate (RMSE, 0.18 BW).

Abstract:
Blood pressure (BP) has always been one of the most important parameters in monitoring cardiovascular system conditions and coronary artery diseases (CAD), such as angina and myocardial infarction (commonly known as a heart attack). This is due to the fact that many of the changes within the cardiovascular system, such as clogged arteries, for example, are reflected by changes in BP. A number of methods and devices that can measure BP are available on the market for both clinical and consumer use. However, being able to measure one’s own BP non-invasively, with the required frequency (even continuously) in a comfortable fashion remains an unsolved problem using currently available systems. To date, the Pulse Transit Time (PTT) measurement method has been seen as a feasible approach to help bring current blood pressure monitoring systems to a stage where non-invasive, continuous measurements are viable. However, developing a system which uses the PTT method for blood pressure measure...

Abstract:
In today's society, the use of watch-based technology is growing steadily and is being used in a wide range of applications and on different aspects of the user's life, from sport and fitness measurement, to entertainment and healthcare evaluation. Considering the multiple application fields for smartwatch/wristbands and their potential adoption in precision medicine applications, it is thus critical to investigate the performance and accuracy of these devices in different potential scenarios of interest. This study investigated the performance and accuracy of a variety of commercially available activity trackers as regards the estimation of stepcount, distance, and heart rate in a number of walking/household/sedentary activities typical in everyday life, and recreated in a lab-environment in a study population of young adults. Results show that heart rate and stepcount measurements are accurate but unstandardized activities, such as common domestic or leisure tasks, may c...

Abstract:
In a road network, cyclists are the group exposed to the maximum amount of risk. Route choice of a cyclist is often based on level of expertise, perceived or actual road risks, personal decisions, weather conditions and a number of other factors. Consequently, cycling tends to be the only significant travel mode where optimised route choice is not based on least-path or least-time. This paper presents an Android platform based mobile-app for personalised route planning of cyclists in Dublin. The mobile-app, apart from its immediate advantage to the cyclists, acts as the departure point for a number of research projects and aids in establishing some critical calibration values for the cycling network in Dublin.

Abstract:
At a time when technological advances are providing new sensor capabilities, novel network capabilities, long-range communications technologies and data interpreting and delivery formats via the World Wide Web, we never before had such opportunities to sense and analyse the environment around us. However, the challenges exist. While measurement and detection of environmental pollutants can be successful under laboratory-controlled conditions, continuous in-situ monitoring remains one of the most challenging aspects of environmental sensing. This paper describes the development and test of a multi-sensor heterogeneous real-time water monitoring system. A multi-sensor system was deployed in the River Lee, County Cork, Ireland to monitor water quality parameters such as pH, temperature, conductivity, turbidity and dissolved oxygen. The R. Lee comprises of a tidal water system that provides an interesting test site to monitor. The multi-sensor system set-up is described and results o...

Abstract:
This letter presents a compact, single-feed, dual-band antenna covering both the 433-MHz and 2.45-GHz Industrial Scientific and Medical (ISM) bands. The antenna has small dimensions of 51 ×28 mm². A square-spiral resonant element is printed on the top layer for the 433-MHz band. The remaining space within the spiral is used to introduce an additional parasitic monopole element on the bottom layer that is resonant at 2.45 GHz. Measured results show that the antenna has a 10-dB return-loss bandwidth of 2 MHz at 433 MHz and 132 MHz at 2.45 GHz, respectively. The antenna has omnidirectional radiation characteristics with a peak realized gain (measured) of -11.5 dBi at 433 MHz and +0.5 dBi at 2.45 GHz, respectively.

Abstract:
Wireless Inertial Measurement Units (WIMUs) are increasingly used to improve our understanding of complex human motion scenarios. In sports this allows for more valid coaching, selection and training methods leading to improved athletic performance. The Push-Start in the Winter Olympic sport of Bob-Skeleton is poorly understood but believed to be critical to performance. At the University of Bath a piece of gym-based equipment called the “Assassin” used by athletes to practice the Push-Start was instrumented with a custom WIMU system to investigate this motion regime. A test subject performed 36 runs, comprising 3 runs at each of 12 combinations of 3 Incline and 4 Weight settings. A developed algorithm automatically identified valid data-files, extracted the Pushing-Phase Acceleration data, and estimated sled Velocity and Displacement. The average velocities derived from an existing Light-Gate and WIMU data-files were comparable, with an average Root Mean Squared Error of 0.105 mete...

Abstract:
Purpose - The purpose of this paper is to develop a highly miniaturized wireless inertial sensor system based on a novel 3D packaging technique using a flexible printed circuit (FPC). The device is very suitable for wearable applications in which small size and lightweight are required such as body area network, medical, sports and entertainment applications.Design/methodology/approach - Modern wireless inertial measurement units are typically implemented on a rigid 2D printed circuit board (PCB). The design concept presented here is based around the use of a novel planar, six-faceted, crucifix or cross-shaped FPC instead of a rigid PCB. A number of specific functional blocks (such as microelectromechanical systems gyroscope and accelerometer sensors, microcontroller (MCU), radio transceiver, antenna, etc.) are first assigned to each of the six faces which are each 1 cm2 in area. The FPC cross is then developed into a 1 cm3, 3D configuration by folding the cross at each of five bend...

Abstract:
Hand motion tracking traditionally requires highly complex and expensive systems in terms of energy and computational demands. A low-power, low-cost system could lead to a revolution in this field as it would not require complex hardware while representing an infrastructure-less ultra-miniature (~ 100μm - [1]) solution. The present paper exploits the Multiple Point Tracking algorithm developed at the Tyndall National Institute as the basic algorithm to perform a series of gesture recognition tasks. The hardware relies upon the combination of a stereoscopic vision of two novel Lensless Smart Sensors (LSS) combined with IR filters and five hand-held LEDs to track. Tracking common gestures generates a six-gestures dataset, which is then employed to train three Machine Learning models: k-Nearest Neighbors, Support Vector Machine and Random Forest. An offline analysis highlights how different LEDs' positions on the hand affect the classification accuracy. The comparison shows how th...

Abstract:
A novel miniaturised system for measurement of the in-flight characteristics of an arrow is introduced in this paper. The system allows the user to measure in-flight parameters such as the arrow’s speed, kinetic energy and momentum, arrow drag and vibrations of the arrow shaft. The system consists of electronics, namely a three axis accelerometer, shock switch, microcontroller and EEPROM memory embedded in the arrow tip. The system also includes a docking station for download and processing of in-flight ballistic data from the tip to provide the measured values. With this system, a user can evaluate and optimize their archery equipment setup based on measured ballistic values. Recent test results taken at NIST show the accuracy of the launch velocities to be within +/- 0.59%, when compared with NIST’s most accurate ballistic chronograph.

Abstract:
Wireless Sensor Networks (WSNs) almost invariably support a centralised network management model. Though the data gathering function is conducted remotely, such data is usually routed via data sinks to central servers for processing, storage, visualisation and interpretation. However, the issue of supporting remote access to WSNs and individual sensor nodes whilst in their physical environment has not been viewed as a priority. It is envisaged that this situation will change as WSNs proliferate in a range of domains, and the potential for supporting innovative revenue-generating services manifest themselves. As a step towards realising such access, a mobile gateway has been designed and implemented. This gateway supports Zigbee as this is the predominant protocol supported by WSNs. Furthermore, it also supports Bluetooth, thereby facilitating interaction with conventional mobile devices. The gateway is programmable according to the needs of arbitrary services and applications.

Abstract:
In this paper, the challenges associated with the design of a novel multi-sensor wearable system for the objective assessment of exercises during lower-limbs rehabilitation are described. The overall system architecture is defined, and finally both the implemented hardware and software platforms are illustrated in detail. Multiple sensing technologies are adopted including motion data, electromyography measurements, and muscle electro-stimulation. The software stack provides guidance to the users throughout the rehabilitation therapy sessions, and allows clinicians to access the data collected remotely in real-time thus supporting their clinical evaluation. Finally, preliminary results of the comparison between the knee joint angle estimated by the developed system against a gold-standard inertial-based system are provided showing promising results for future validation.

Abstract:
This work performs an extensive charterisation of precision targeted throwing in professional and recreational darts. The goal is to identify the contributing factors for lateral drift or throwing inaccuracy in the horizontal plane. A multitechnology approach is adopted whereby a custom built body area network of wireless inertial measurement devices monitor tilt, force and timing, an optical 3D motion capture system provides a complete kinematic model of the subject, electromyography sensors monitor muscle activation patterns and a force plate and pressure mat capture tactile pressure and force measurements. The study introduces the concept of constant throwing rhythm and highlights how landing errors in the horizontal plane can be attributable to a number of variations in arm force and speed, centre of gravity and the movements of some of the bodies non throw related extremities.
