RF Energy Harvesting & Wireless Power: RFID Deployments & Sensor Applications
Santa Clara Convention Center, CA, USA
Grand Ballroom F
16:30 - 16:50
This session will cover existing and new deployments of RF energy harvesting and wireless power in sensor networks across various industries and applications. Real-world deployments will be examined along with the problems "power over distance" has solved, including remote battery recharging and powering battery-free designs.
Dr. Charles Greene, Chief Operating & Technical Officer at Powercast Corporation, received a B.S., M.S., and Ph.D. in Electrical Engineering from the University of Pittsburgh in 2001, 2002, and 2006, respectively. Dr. Greene has over seventeen years of experience in the Radio Frequency (RF) field, including sixteen years at Powercast Corporation. He is a leading expert in wireless power transfer, antenna design, and RFID. He has over twenty issued U.S. patents and numerous other foreign and pending applications in the wireless power and RFID fields. Dr. Greene has published numerous articles and has presented at various industry-leading conferences in the U.S., Europe, and Japan.
Creating a power coverage area, Powercast's RF wireless power transmitters automatically power enabled products that come within range for smart, carefree wireless charging. Charging range and rate depend on a device's power consumption; power-hungry products charge best at close range, while the transmitters can power low-power devices such as sensors up to 80 feet (24 meters). The transmitters use the 915-MHz ISM band to send RF energy over the air to Powercast's tiny Powerharvester® receiver chip embedded in products, which converts it to usable direct current (DC) to either directly power batteryless devices, or recharge devices' batteries. The robust technology complies with the FCC's current one-watt power limit for Part 15 deployments in this band, but has potential power capabilities well beyond that to evolve as FCC standards evolve.
