Session 18 Overview: Biomedical Devices, Circuits, and Systems

This session covers biomedical systems with innovations that traverse device, circuit, and system-level design. The first paper describes a retinal prosthetic that utilizes an optically-addressed nanowire array in conjunction with a transmitter-offloaded wireless neural stimulation approach for efficient operation near sensitive retinal tissue. A pneumatic-free fully-CMOS-controlled microfluidics platform for label-free cellular and bio-molecular sensing comes next, followed by a CMOS microscopic-scale thermal actuation and sensing array for localized heating of magnetic nanoparticles for hyperthermia cancer therapy. The final paper showcases a wireless multimode IC integrating electrochemical sensors, a temperature sensor, and a current stimulator for monitoring chronic wound healing processes.
