A Powercaster™ transmitter chip, running on conventional current, broadcasts a low-power radio (RF) signal at a specific frequency across several feet of empty space. Powerharvester™ receiver chips built into one or more remote devices capture enough energy to continuously recharge batteries, or to power devices directly.

Patented algorithms more than double the effective range of conventional RF power output. A patented circuit design captures up to 70% of the theoretical maximum anywhere within the Powercaster’s range.
