Batteryless Sensor Using a Nanoenergy Harvester

Existing nanosensor technologies depend on an external power source (typically a battery) to operate. Lawrence Livermore National Laboratory has developed a superior alternative: the first batteryless sensors that harvest environmental energy supplies using one-dimensional semiconducting nanowire arrays. The commercial applications for this technology include readily deployable self-powered chemical sensors for military, industrial, medical, and environmental applications. By freeing the nanosensor from a tethered power supply, LLNL scientists have provided the new standard for portable chemical detectors.
Abstract: 
Chemical and biological sensors based on nanowire or nanotube technologies exhibit observable ultrasensitive detection limits due to their unusually large surface-to-volume architecture. This suggests that nanosensors can provide a distinct advantage over conventional designs.
