RF wireless power technology reduces battery use, E-waste

Powercast’s over-the-air RF wireless power recharges batteries or replaces them altogether

September 9, 2021  EP&T Magazine

Powercast Corp., an established leader in RF wireless power, has received recognition for its efforts in sustainability, when it comes to battery re-use.

Powercast aims to make one-time-use batteries obsolete by working with electronic manufacturers to recharge batteries or replace them altogether with its over-the-air RF (radio frequency) wireless power technology. Many of today’s small electronic devices can be designed so they’re environmentally friendly, either with rechargeable batteries that can accept an RF wireless charge, or with no batteries that can be directly powered by RF power. A Powerharvester chip is embedded in devices to receive RF energy sent over the air from either a dedicated Powercast transmitter, or from industry-standard RFID readers. The Powerharvester then converts the RF to direct current (DC) to top off the battery or power the device.

Powercast’s RF Wireless Power Technology Wins Global Sustainability Award for Reducing Battery Use, E-Waste

Powercast’s technology was recently awarded by the Business Intelligence Group with its Sustainability Initiative of the Year in the 2021 Sustainability Awards program. These awards honor those people, teams and organizations who have made sustainability an integral part of their business practice or overall mission.

Energy harvesting touches millions

Powercast’s energy harvesting touches millions of users across 15+ industries, including automotive, consumer electronics, IoT, entertainment, retail, RFID, and sensors. The company’s collaborative approach and expertise in all aspects of product design, from vision through prototyping and commercialization, has resulted in dozens of applications and millions of units shipped.

“We’re already partnering with many manufacturers to create wirelessly rechargeable devices that keep batteries out of landfills,” said Charles Goetz, CEO of Powercast. “But, we strive for the day where all devices will charge in the background when consumers enter their home, office or car, where they’ll never have to throw batteries away.”
