Abstract
A device for a handle able to be deployed in relation to a motor vehicle door. The device includes a primary module integrated into the door, supplying power, through inductive coupling, to a secondary module integrated into the handle and that moves in relation to the primary module along a predetermined path when the door handle moves between a deployed position and a retracted position. An advantageous arrangement of two primary coils of the primary module and of a secondary coil of the secondary module allows the device to estimate the position of the door handle. Furthermore, the device makes it possible to establish a wireless communication link between the primary module and the secondary module.
