A Wireless and Digital Electrode Bus Topology for Biopotential Measurement
(2012)

Abstract:
The conventional biopotential measurement configuration utilises long lead wires which connect measuring electrodes to signal conditioning circuitry. The majority of bioelectric signals that are measured from the human body have a tiny signal amplitude (5µV-5mV range) and thus any interference that is induced on the lead wires can have a detrimental effect on the original signal. In this paper, we present an alternative configuration, in which digitisation occurs on the electrode, potentially providing enhanced signal measurement as well as significant benefits in terms of the simplification of the physical interconnections between electrodes. Multiple electrodes are combined to form a digital electrode bus. This proposed topology represents the next stage in the evolution of bioelectric measurement as, due to the decrease in cost and size of integrated circuits, more of the bioinstrumentation circuitry is shifted away from a base measurement station and into the electrode itself.

Ultrasonically powered compact implantable dust for optogenetics

Abstract:
This paper presents an ultrasonically powered microsystem for deep tissue optogenetic stimulation. All the phases in developing the prototype starting from modelling the piezoelectric crystal used for energy harvesting, design, simulation and measurement of the chip, and finally testing the whole system in a mimicking setup are explained. The developed system is composed of a piezoelectric harvesting cube, a rectifier chip, and a micro-scale custom-designed light-emitting-diode (LED), and envisioned to be used for freely moving animal studies. The proposed rectifier chip with a silicon area of 300 μm × 300 μm is implemented in standard TSMC 0.18 μm CMOS technology, for interfacing the piezoelectric cube and the microLED. Experimental results show that the proposed microsystem produces an available electrical power of 2.2 mW while loaded by a microLED, out of an acoustic intensity of 7.2 mW/mm 2 using a (1 mm) 3 crystal as the receiver. The whole system including the tested rectifier...
