Powercast Aims RF-based Charging Kit at Consumer Goods
The company is selling an evaluation kit to manufacturers of mobile phones, gaming remotes and other wireless devices to test technology that enables the charging of those devices without wires.

Powercast is selling a development kit that contains the hardware and apps consumer goods manufacturers need to incorporate wireless power-harvesting technology into their wireless products. The kit is intended to enable companies to test wireless charging on their own power-using mobile devices. The long-term aim, according to Powercast, is for businesses to begin building recharging functionality into their products. Devices that could benefit from the technology include remote controls, gaming devices, ear buds, hearing aids, wireless sensors, and wearables, as well as active radio frequency identification (RFID) tags, or Near Field Communication (NFC) and Bluetooth Low Energy (BLE) devices.
Powercast, a Pittsburg-based wireless power company, was launched 14 years ago to build solutions that charge batteries via RF signals. Traditionally, the firm has focused on products that harvest RF signals for the industrial or commercial market. It makes, for instance, a solution for powering devices used by heating, ventilation and air conditioning (HVAC) products (see Powercast Debuts Energy-Harvesting Wireless Sensor System). The company launched its solution for the commercial sector with a development kit in 2010.
Now, Powercast has added consumer goods to its portfolio of applications. The company has noted the growing demand for wireless charging in the consumer market, says Charlie Greene, Powercast's chief operating and technical officer. "The number of devices that require charging is growing," he explains, and that growth was recently illustrated when Apple eliminated the wire jack for earbuds, which requires that users now recharge the earbuds as well as their phone. "That's just one more thing that had to be plugged in" for recharging, he adds.
The P1110-EVAL-01 development kit includes an FCC-approved Powercaster transmitter, battery-recharging boards (in applicable shapes such as for wristbands or smart cards), a Powerharvester evaluation board and receiving antennas, BLE radio boards, and the first version of its new PowerSpot transmitter. PowerSpot, the next generation of the Powercast transmitter, will measure approximately one-fourth the size of its industrial-focused counterpart, the company reports; it measures about 7 inches in length by 2 inches in height by 0.75 inch in depth, and is designed for consumer-facing applications.
The system could be used to power wearable sensors or devices such as heated jackets or illuminated safety vests. It could also be employed by active RFID-enabled devices, such as smart wristbands worn by passengers on cruise lines or attendees at theme parks, so that they could be reused.
