SEMICONDUCTOR ELECTROMECHANICAL TRANSDUCER ELEMENT HAVING A P-N-P OR N-P-N AMPLIFYING JUNCTION INTEGRALLY ASSOCIATED WITH A STRAIN-SENSITIVE REGION

摘要

A highly sensitive, stable output, electromechanical semiconductor transducer element is formed from a unitary body of a semiconductor material wherein three regions are formed to provide a strain-sensitive region and P-N junctions which can provide a high gain electrical output which is based on a piezoresistive effect produced in the strain-sensitive region which is amplified by the presence of P-N junctions.
