Wearable Thermoelectric Generators for First Responders

This SBIR Phase I will model and physically demonstrate wearable, small factor, and lightweight thermoelectric generator prototypes powered by human body heat. The project will make use of Perpetua`s novel Flexible Thermoelectric Film technology to yield higher voltages and power from small active areas. End devices will be in wearable form factors, including a flexible button array that can be integrated into textiles, harnesses, helmets, and other gear. Challenges to overcome center around thermal optimization specific to the unique conditions of wearables. Phase I prototypes will power autonomous low power wireless transceivers. No commercially viable wearable thermoelectric energy harvesting system has ever been brought to market due to the counteracting difficulties of achieving a small form factor while still providing sufficient voltage to power a wireless transceiver. The resulting renewable thermoelectric generators will reduce and in some cases eliminate the need for battery replacements. Market applications include safety diagnostic systems for emergency responders, situational awareness for Incident Commanders, along with related medical and military applications.
