Abstract:
1. An apparatus, comprising: a sensor capacitor based on at least one pair of parallel conductor surfaces; a housing to encompass the sensor capacitor, wherein the housing is composed of a low creep material which includes at least one of a 17-4 PH stainless steel, a 15-5 PH stainless steel, and a maraging stainless steel; a digitizer module in the housing to generate a digital measurement based on a change in a capacitance of the sensor capacitor when a contact zone of the housing is deflected by a force applied on the contact zone; a compensation module of the digitizer module to apply another digital measurement of at least one distortion factor to the digital measurement to minimize an effect of the at least one distortion factor to the apparatus; and a communication module to communicate at least one of an analog signal and a digital signal through at least one of a wired channel and a wireless channel, wherein the at least one of the analog signal and the digital signal to include at least the change in the capacitance.
