First supercapacitor that can be charged by human body heat

14.11.2016 | Texas A&M University | engineering.tamu.edu

Engineers from Texas A&M University have developed a new concept of electrical energy storage: Thermally Chargeable Solid-state Supercapacitor.

This innovative supercapacitor allows charging to be completed using thermal energy in addition to the traditional electrical charging method for capacitors.

Supercapacitor charged by human body heat

The Thermally Chargeable Solid-state Supercapacitor works by converting thermal energy into electrical energy and then storing it in the device at the same time. For example, human body heat, or any heat dissipating objects that create temperature differences from their surroundings can be used to charge the capacitor without external electrical power sources.

The supercapacitor is also flexible in that it can be used as a power supply for wearable electronics, and can be integrated into wireless data transmission systems to operate IoT (internet of things) sensors. IoT is a concept of connecting various electronic devices and sensors for data communication and exchange, which is particularly useful in real-time monitoring.
