Abstract: A force sensing device is disclosed that includes a housing tip, a plurality of sensors stationarily spaced from each other, and a spring element connecting the housing tip to the sensors such that moving the housing tip and the sensor relative to each other causes a resilient deformation of the spring element. The spring element is configured to arrange the housing tip in a zero position relative to the sensors by a spring force of the spring element. The force sensing device is also equipped with a spring tensioning structure configured to adapt the spring force of the spring element.
