The invention relates to a sensor for electrically measuring a force acting on the sensor, which force is distributed unevenly over a measurement surface (10) of the sensor, wherein an electrical force measurement signal is generated. A flat spring device (20) is provided between the measurement surface (10) and a counter surface (11). A first measurement element is arranged in or on the measurement surface (10) and a second measurement element is arranged in or on the counter surface (11), in such a way that the measurement elements substantially completely cover the respective surfaces. The measurement elements, e.g., capacitor plates, are designed in such a way that the measurement signal can be generated from a distance between the measurement elements. The spring device (20) has a plurality of incompressible but elastic spring bodies (21 to 213), which are arranged so as to be separated from each other by gaps (22) and in such a way that each spring body (21 to 213) can deform into the gaps (22) and thus in a space-occupying manner when loaded with the force or a fraction of said force. This measuring assembly allows for the measurement of unevenly distributed forces between bodies, which can be shaped very differently. |
