ABSTRACT:
An apparatus for measuring force has a resistive element which has an electrical resistance which varies as a function of force applied to the transducer. An electrical output signal related to the resistance of the element has a sufficient magnitude so that it can be fed directly to processing circuitry without any amplification. This is accomplished by modulating the electrical power supplied to the resistive element to enhance the electrical output signal.
