Remote Power - How It Works

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.

Contactless Power - How It Works

Running on conventional current, a Powercaster™ element generates a safe energy field designed to be a few millimeters or centimeters deep. A matching Powerharvester™ element entering the field captures energy and generates useful current, even if the elements are separated by open space or solid matter. That current can recharge a battery or directly power an electronic device.

At efficiencies nearing 90%, patented Powercast technology transfers power between compact components that fit inside products without adding bulk.
