Claim Text:
1. An apparatus comprising: at least one sensing capacitor, and a controller, configured to receive a signal from the at least one sensing capacitor indicative of a change of charge of the sensing capacitor, wherein the controller is configured to determine a plurality of: an amount of force applied to the sensing capacitor, an acceleration of the sensing capacitor, a torsion of the sensing capacitor, a vibration of the sensing capacitor or a pulling force applied to the sensing capacitor, based on the change of charge of the at least one sensing capacitor, wherein the at least one sensing capacitor is coupled to a printed circuit board (PCB), wherein the PCB comprises cuts in form of segments of a circle, wherein at least a first and at least a second cut are arranged symmetrically and mirrored around a centre of the circle, and wherein the at least one sensing capacitor is coupled to the PCB at the centre of the circle or between the first and second cuts.
