We utilize the state-of-the-art in low power RF transmitters, low voltage boost circuits, subthreshold processing, biosignal front-ends, dynamic power management, and energy harvesting to realize an integrated reconfigurable wireless body-area-sensor node (BASN) SoC capable of autonomous power management for battery-free operation. Conventional wireless sensors are powered from a battery (Fig. 17.4.1), limiting node lifetime. In contrast, we propose a wireless BASN chip powered by energy harvested from human body heat using a thermoelectric generator (TEG). This,
