Abstract

A novel design of a strain gage transducer in an elliptical configuration is presented. The transducer forms one arm of a bridge circuit whose output is amplified and filtered by either a single-chip or multichip circuit. The transducer system is proved to be highly linear. Performance of the single-chip instrumentation amplifier was superior to the multichip design. Fewer discrete and integrated components greatly reduces drift and noise within the circuit, thus improving performance and predictability. Output signal buffering and filtering are handled by additional active stages utilizing standard design techniques. The design of the transducer system permits its application to most biomedical applications, particularly mechanical parameters such as diameter and force measurements.
