Abstract

Powering of wearables and implants is a critical challenge. Conventional batteries are rigid and require frequent recharging and/or replacement, making their use cumbersome and obtrusive for body-area applications. Instead, this paper discusses three novel technologies that our group has recently explored toward batteryless wearables and implants, viz. a) DC power generation using fabric electrochemistry, b) Radio-Frequency (RF) power harvesting, and c) fully-passive RF backscattering. Notably, the proposed technologies bring forward transformational possibilities for batteryless sensing and/or stimulation.
