Profile
Creating a power coverage area, Powercast's RF wireless power transmitters automatically power enabled products that come within range for smart, carefree wireless charging. Charging range and rate depend on a device's power consumption; power-hungry products charge best at close range, while the transmitters can power low-power devices such as sensors up to 80 feet (24 meters). The transmitters use the 915-MHz ISM band to send RF energy over the air to Powercast's tiny Powerharvester® receiver chip embedded in products, which converts it to usable direct current (DC) to either directly power batteryless devices, or recharge devices' batteries. The robust technology complies with the FCC's current one-watt power limit for Part 15 deployments in this band, but has potential power capabilities well beyond that to evolve as FCC standards evolve.

Energy harvesting and wireless sensors ready for prime time
Energy harvesting is the conversion of ambient energy into electricity to drive small or mobile electronic and electrical devices. Wireless sensors are particularly in need of energy harvesting because they are increasingly deployed in numbers and locations where hard wiring or battery changing are impracticable. We are at an exciting stage with both because harvesting is becoming better and electronics is demanding less power -so they meet in the middle.12 Aug 2010
Real Time Locating and Wireless Sensor Networks - Rapid Advances
In the past, too much use of RFID has involved sensing items and conveyances only when they pass very near to the occasional interrogator. Heroic assumptions are then made about what happened in between. Was it destroyed, perhaps by overheating? Is it still there? Is it intact?16 Apr 2010
