Sensor module, sensor system and method for capacitive and spatially resolved detection of an approach and touch, use of the sensor module

摘要

The present invention relates to a sensor module, a sensor system and a method for the capacitive and spatially resolved detection of the approach of objects to the sensor module and for the capacitive and spatially resolved detection of tactile events between objects and the sensor module. In addition, the invention relates to a use of the sensor module or the sensor system. In this case, the sensor module comprises a sensor element (100), which has a first, second and third layer, wherein the first layer comprises a plurality of electrically conductive cover electrodes (13), wherein the second layer (10) is deformable and electrically insulating, wherein the third layer having an electrically conductive bottom electrode (8), wherein the second layer is disposed between the first and third layers, wherein the first and third layers are the only electrically conductive layers of the sensor element (100), and wherein the sensor element (100) designed is to be operated in three different measurement configurations, namely in a self-capacitive proximity configuration, a bilateral-capacitive proximity configuration and a bilateral-capacitive tactility configuration.
