Energy-Autonomous Circuits: Starting Cold and Keeping Alive
January 30 @ 5:30 pm - 6:30 pm
Abstract:
Portable electronic devices are ubiquitously rising, but are predominantly powered by batteries that require recharge/replacement to extend operation lifetime. Future devices, especially for energy-constrained applications like continuous biosensing or remote environmental monitoring, require energy-autonomy for seamless long-term operation. Ambient energy harvesting can be a sustainable way of powering these devices, but integrated circuits (IC) or chips need to start and function intelligently with the small available energy.
In this talk I will present (a) ultra-low-voltage CMOS circuits for self-start and efficient power extraction from body-heat, and (c) ultra-low-power circuit architecture for motion-adaptive heartbeat detection to demonstrate a truly battery-less wearable bioelectronic sensing system-on-chip (SoC). I will conclude the talk with research areas that my group, BRICS at UC Santa Cruz will be working on soon.
