Abstract: The present disclosure relates to compensation circuitry for compensating for a thermal effect in an output signal output by a force sensor. The compensation circuitry comprises monitoring circuitry configured to monitor one or more electrical parameters of the resistive force sensor and processing circuitry. The processing circuitry is configured to determine an absolute resistance value for the force sensor based on the one or more monitored electrical parameters and to adjust one or more operational parameters of the force sensor system based at least in part on the determined absolute resistance value.
