Research: Low-cost health monitoring is the primary healthcare solution that can ensure healthy lives and promote the overall quality of well-being. This requires seamless transduction of biological information to electrical domain for faster data processing and communication. This project proposes passive wireless neural recording to enable zero-power monitoring of action potentials that guide the heart and brain functions. By utilizing low-impedance microelectrode arrays coupled with RF interfaces, continuous monitoring with ECG and EEG is possible without extensive electronic integration. The main challenge to realizing such systems is the development of high-capacitance porous platinum electrode arrays on flexible substrates. This research task has focused on developing such electrodes and demonstrating their superior neural recording performance. Various electrode designs and processes have been investigated to achieve impedance-matched neural recording.
