MicroGen’s Bolt sensor is smaller than a quarter.
MicroGen Systems and Cornell University’s Cornell Nanoscale Facility have collaborated to develop battery-free sensors that can operate in anything that spins or shakes. The battery is a tiny sheet of piezoelectric material that generates electricity when flexed. Called Bolt, the energy harvesting device is intended to enable low power electronic devices, such as nodes for wireless sensor networks.
