WIRELESS SENSORS - Energy harvesting - No single energy harvesting technology can serve all applications

摘要

MANY industrial end users will continue to resist adopting wireless sensing as long as these sensors require batteries, which must be replaced. While suppliers have made improvements in battery life, powering wireless sensors via energy harvesting is a potential game changer in both industrial and building automation. Harvesting is not one technology, but several, and the newest energy harvesting technology - thermoelectric generation - made significant progress toward commercialisation in 2010.
