Energy Scavenging XPRIZE
The Internet has made it possible to network a multitude of devices. However, challenges remain in finding affordable and convenient mechanisms to power small wireless electronic devices/sensors over long periods of time in remote locations (e.g. temperature sensors embedded in the walls of buildings). Fuel storage systems and traditional electrochemical batteries are limited by factors such as fuel supply, battery life, and weight. The ability to leverage small energy fluxes from temperature, pressure, vibration, light, and radio waves in the environment could hold promise for providing mobility, flexibility, and energy efficiency. The purpose of this prize is to bring about a new mechanism for powering countless small, remotely-located sensors over long periods of time from ambient power in the environment.
