Body-Coupled Powering for Wearables

Abstract

Providing power to body-worn sensors and nodes is challenging. Energy Harvesting (EH) often faces source-destination location mismatch issues. Batteries are bulky and lead to "battery anxiety" as the number of nodes increases. Body-Coupled Power (BCP) Transfer and Energy Harvesting, on the other hand, uses the human body as a coupling medium to effectively distribute power on/around the human body. With the BCP, energy harvesters can be used without location constraints, and a single power source can provide power to multiple wearables around the body.
