Abstract

Ambient environmental effects can often interfere with transducers and affect the accuracy of sensor readings. A typical method of compensating for temperature in strain measurements is to construct a full-bridge Wheatstone circuit. The objective of this study was to design patterned nanocomposites deposited onto fabric substrates to form a materials-based Wheatstone bridge circuit that could automatically compensate for unwanted ambient effects. Motion Tape (i.e., a self-adhesive, elastic-fabric-based nanocomposite sensor) specimens with patterned nanocomposite elements and conductive traces were designed to form a full-bridge circuit. The results showed that their strain sensing response was not adversely affected by concurrent temperature effects.
