ABSTRACT:
A hybrid transducer employing a ceramic substrate having on a surface a suitable geometry for defining an active or clamped area, a semiconductor strain gage is positioned on said substrate within said active area and connections are made to said gage by conductors printed on said substrate by thick or thin film techniques. Thick film printing techniques or thin film deposition techniques are employed to print the conductors, terminal areas, compensating resistors and stop members.
