METAL AIR SCAVENGER - AN ENERGY HARVESTING TECHNOLOGY FOR POWERING ELECTRONICS AND ROBOTICS

Provided are metal-air scavenger systems that use metal surfaces to harvest energy for powering microelectronic devices; such devices can be attached to exposed metal surfaces and then generate power by electrochemically oxidizing the metal surface. The disclosed devices can be configured to effect relative motion between the device and the metal, thus allowing the device to utilize an entire metal surface to generate power and also allowing the device to feed metal to itself to generate power.
