ABSTRACT:
The disposable transducer includes a small housing constructed of lightweight plastic material. The housing is shaped so as to form a transparent chamber within which is situated a very small piezoresistive strain gauge in the form of a resistive bridge network diffused onto a semiconductor substrate. The semiconductor substrate is electrically isolated by means of a nonconductive gel which partially fills the transparent chamber in which the semiconductor substrate is positioned. The resistive bridge network of the semiconductor substrate is also electrically connected to a plurality of calibration resistors which are separately formed on the semiconductor substrate, making the entire apparatus economically disposable after a single use.
