History

While the world has focused on using radio waves for communication, Powercast has focused on capturing radio waves to power devices. Founded in 2003, Powercast developed a receiver module with breakthrough efficiency levels. Coupled with a transmitter that sends RF energy using algorithms developed by Powercast, the Powercast Wireless Power Platform™ was born. While the concept of sending power "through the air" has been discussed for more than 100 years, Powercast is the first company to make it commercially viable. Powercast is now leading the cross-industry initiative to bring wireless power to a hundreds of low power devices.

Products

Powercast has developed a transmitter module, called a Powercaster™ and a receiver module called the Powerharvester™. Both are ingredients that we expect will be embedded in hundreds of future products. So, while Powercast does not sell a packaged product that you will be able to buy off the shelf, we do provide the modules to OEMs (Original Equipment Manufacturers). The patented Powercast platform makes it possible to design and manufacture revolutionary products that are charged - or even powered directly - without wires.

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.
