Abstract

The invention relates to a human-machine interface device with a transparent detection area and an access area, said device comprising: in the detection area a surface with electrodes made of transparent conductive material arranged in said access area and connected to said Conductive connection tracks of the surface with electrodes, a first conductive surface made of transparent material present in the transparent area and serving as protection for said surface with electrodes. Conductive connection tracks are arranged between the second and third conductive surfaces of the second and third protection means serving as these conductive connection tracks. The device also includes coupling tracks made of a transparent conductive material to connect the conductive connection tracks to the electrodes of the surface having the electrodes, the coupling tracks being positioned between the electrodes when the connection tracks are on the detection surface, and when these The link track is positioned between the second and third guards when located in the access area.

Description

technical field [0001] The invention relates to a device for capacitive measurements between an object and an electrode array. It finds particular application in the general field of 2D capacitive touch surfaces and 3D capacitive detection for human-machine interface commands. Background technique [0002] Devices for communication and work are increasingly utilizing touch-command interfaces such as panels or screens. For example, a mobile phone, a smart phone, an electronic notebook, a personal computer, a mouse device, a touch panel, a widescreen monitor, etc. are mentioned. [0003] A large number of these interfaces utilize capacitive techniques. The touch surface is equipped with conductive electrodes connected to the electronics, making it possible to measure the change in capacitance generated between the electrodes and the object to be sensed to execute commands. [0004] Current capacitive technologies most often use two layers of conductive electrodes in the for...
