Abstract :
It is demonstrated that piezoelectric elements are quite suitable for measuring static forces. This is achieved by measuring the variations of the piezoelectric sensor series resonance branch at its first resonance mode, which accurately reflects the measured force. A simple electronic interface circuit was designed to experimentally validate this new concept
