How does it work ?


energysquare’s Power by Contact© charging solution works by electrical conduction :
It consists of a transmitter and a receiver.
– The transmitter is made of conductive tiles monitored by a transmitting circuit, controlled by a detection algorithm and a charge monitoring system.
– The receiver is a device equipped with two conductive electrodes, monitored by a receiving circuit, connected to the device’s battery.
The technology works through the contact between the receiver’s electrodes and the transmitter’s tiles : the transmitter will detect the receiver, communicate with it and activate the appropriate power.

Power by Contact© Transmitter


A Power by Contact© Transmitter or Tx is an electronic device able to communicate and charge devices equipped with the technology. It can be a standalone “plug-and-play” device to place anywhere, or a built-in appliance to integrate into another product.

Transmitter’s design has been thought to be easily customizable to your needs.

Its size, tile number, shape and dimensions can be adapted to fit your use-case.

The transmitter’s electrical circuit can be designed to support multiple voltages and standards.

Power by Contact© Receiver


A Power by Contact© receiver or Rx is an electronic device equipped with the technology. It can be a device embedding the technology, or an already existing device equipped with an adapter.
An Rx needs at least two receiving electrodes, which must have direct contact with the Tx. This allows communication and power transfer between the receiver circuit and the Tx.
