A method of and apparatus for measuring a stimulus, e.g. a force, applied to a piezoelectric transducer. The method comprises sampling the output of the transducer in response to the stimulus at intervals during application of the stimulus, resetting the output of the transducer to a predetermined value immediately following each sampling step, and summing the values of the sampled transducer output for each sampling step to provide a value indicative of the total applied stimulus. The apparatus of the invention comprises a sensor for sensing the transducer output in response to the stimulus a sampling circuit for sampling the sensed output at intervals during application of the force, a switch for resetting the output of transducer to a predetermined value immediately following each sampling operation, and circuitry for summing the values of the sampled transducer output for each sampling step and generating from them an output value indicative of the total applied stimulus.
