Abstract

A force sensor particularly suited for use in an electronic stylus that senses an applied force on its nib for recording pen strokes and handwriting recognition. The sensor has a load bearing member for receiving an input force to be sensed and associated circuitry for converting the input force into an output signal indicative of the input force. A coupling at least partially transmits the applied force to be the input force acting on the load bearing member. The force transfer coupling transferring the forces so that the applied force and the input force are not co-linear.
