Abstract: An electrically isolated semi-conductor transducer and method of making the same wherein a unitary piece of silicon material having opposed flat surfaces is carved out about a central portion thereof through one flat surface forming a toroidally-shaped cavity having curved bottom surfaces partway through said material surrounding a push rod having an upper flat surface lying in the same horizontal plane as the remainder of said carved out flat surface. The upper flat surface of the push rod and the curved carved surfaces surrounding the push rod are etched exposing the silicon material. A plurality of strain gages are provided on the opposite flat uncarved surface of said silicon material. These strain gages may include four diffused silicon strain gages at spaced locations along said uncarved surface.
