Abstract
Leakage current is reduced in a piezoresistive transducer by forming a leakage barrier around a piezoresistive element of a piezoresistive transducer. The leakage barrier prevents the formation of a parasitic leakage path in the substrate thereby reducing the leakage current flowing through sections of the piezoresistive element, and stabilizing the resistance value and the output voltage of the piezoresistive transducer.
