SENSOR DEVICE AS WELL AS METHOD FOR PROXIMITY AND TOUCH DETECTION

摘要

The invention provides a sensor device with a first electrode structure and a second electrode structure, the first electrode structure comprising a transmitting electrode, a compensation electrode and a reception electrode and the second electrode structure comprising a field transmission electrode and at least one field sensing electrode. The first electrode structure is adapted to detect a gripping of an electric hand-held device, whereas the second electrode structure is adapted to detect an approach of a finger to the second electrode structure, for example of the hand gripping the hand-held device.
