Converting body heat into reliable energy for powering physiological wireless sensors

Wearable thermoelectric generator (WTEG) technology is a unique energy harvesting application currently being developed by Perpetua Power Source Technologies for powering low-power transceivers and physiological monitoring sensors using body heat as an always-available power source. Integrated into wearable structures, such as an armband, clothing patch or directly embedded into a low-power wireless monitoring device, WTEGs utilize heat from the body and convert it into electrical energy. WTEG technology can be used to renewably and reliably power on-body sensors that can wirelessly monitor an individual's location or a specific physiological condition.
