Powercast are the current leader in over the air wireless power using radio frequency waves (RF wireless power). Powercast has recently announced shipments of RF Powerharvester® PCC110 chips have reached over 10 million in the last two year. The end-device uses of these chips include IoT sensors, digital luggage tags, consumer electronics, logistics and more. Powercast claims its technology can deliver power remotely up to 24 metres (80 feet).
This milestone achievement gives a good impression of the current size of the market for RF wireless power solutions, especially as Powercast are one of the few companies currently shipping products to customers. Whether Powercast can maintain its early advantage in the market, or if its competitors (several of whom are actively preparing for launch) will catch up remains to be seen.
