Technology[edit]

The company's technology is based upon Inductively Coupled Power Transfer. As the block diagram shows, within a Transmitter (Tx) - by varying the current in the primary induction coil - an alternating magnetic field is generated from within a charging spot. The receiver (Rx) is a second induction coil in the handheld device that takes power from the magnetic field and converts it back into electric current to charge the device battery. An additional part of the technology is the System Control Communication: Data over Coil (DoC) – the Rx sends feedback to Tx by changing the load seen by the Tx coil. The protocol is frequency based signaling, thus enables fast response of the transmitter. Each receiver is equipped with a unique ID (RxID), enabling the system, when installed in public venues, to recognize users and communicate with them. The RxID is communicated as part of the data over coil to the Tx.
History
The company was founded in 2006 by Ran Poliakine. Its first products were launched in 2009.

In October 2012, Powermat and Starbucks announced a pilot program to install Powermat charging surfaces in the table tops in 17 locations around Boston area. The technology is consistent with Starbucks' environment friendly guidelines. [8] As the pilot was completed, in July 2013, Starbucks decided to bring the Powermat's wireless charging tech to additional locations in the Silicon Valley. [9] Powermat announced it had acquired Powerkiss, a provider of integrated wireless charging solutions. Powerkiss had deployed wireless charging hot spots across Europe, founded in 2008 and headquartered in Helsinki, Finland.In November 2013 the company announced a deployment at some Coffee Bean and Tea Leaf locations. Additional Powermat systems are installed at McDonalds restaurants in New York City and in select locations in Europe. [10] In January 2014, the company, together with Flextronics, agreed to cooperate in order to embed wireless power in electronic mobile devices. [11]
