Rezence is a wireless charging technology and specification based on the principles of magnetic resonance and developed to wirelessly power smartphones, tablets, wearable computing devices and other mobile electronics. The name Rezence is derived from the words resonance and essence.
The Alliance for Wireless Power (A4WP) organization is responsible for maintaining, promoting and evolving the Rezence technology. The A4WP was formed in 2012, and it launched the Rezence name and compatibility program in late 2013. The non-profit organization also revealed the Rezence logo at that time, a lightning bolt between a bottom and top bracket that together form the letter “Z.”
The Nascent But Heated Wireless Charging Battle
Rezence contends in the nascent wireless charging sector with a number of competing standards, including the Wireless Power Consortium’s Qi and the Power Matters Alliance’s PowerMat. In February 2014, the A4WP and the Power Matters Alliance signed an agreement to adopt each other’s technologies for greater compatibility and a higher likelihood of gaining mainstream acceptance.
Intel is expected to include Rezence support in its upcoming line of Skylake miroprocessors. Other key supporters and company members of the A4WP include Samsung, Broadcom, and Integrated Device Technology (IDT).
