RF-Powered Wireless Sensors

Powercast’s TX91501 Powercaster transmitter was selected by EDN for the Hot 100 Products of 2010. This transmitter sends both power and data for remote powering/charging in conjunction with Powercast’s P1110 or P2110 Powerharvester receivers.

Broadcasted RF energy creates a predictable, controllable power source to provide power-over-distance and one-to-many charging.  Unlike potentially unreliable or intermittent solar, heat or vibration micro-power energy sources, the TX91501 transmitter sends power to enable wireless devices to charge and operate completely untethered from the power source, and power can be sent on-demand, scheduled, or continuously.  End-devices can be inherently dormant, with zero-standby power, until power is sent to operate the device, or batteries can be trickle-charged remotely.  The operating distance for wireless power transfer (wireless charging) from the TX91501 transmitter to a device with the P2110 Powerharvester Receiver is about 40 feet with a reasonable size receiving antenna.
