WP7: Biomedical Circuits and Systems

The global market for medical electronics is projected to reach $8.8 billion by 2026, driven by factors such as an aging population, increasing awareness about healthcare and disease prevention and proliferation of user-friendly electronic systems, such as smartphones, smart watches, fitness trackers etc. Medical electronic systems require circuits, which can bi-directionally interface with the (neuro)biological systems in wearable, implantable or in-vitro formats as required by the application. Such interface circuits must not only read out weak bioelectronic signals with high accuracy under noisy and high-interference conditions but may also need to provide precise delivery of electrical stimuli for therapy or culture activation while respecting extreme power and size constraints, especially for implantable devices. We propose technological innovations enabling bi-directional operation with respect to bioelectronic readout and stimulation for in-vivo and in-vitro applications, high-throughput wireless data readout for battery-operated implantable devices and AI embedded chips and networked devices. We aim to prototype the new biomedical systems in applications such as biomedical-implants, wearable health trackers, neuromodulation devices, and devices for in-vitro bioelectronics, and functional characterization in drug-screening scenarios.
