Cellulose Acetate Substrates for Design and Calibration of Strain Gauges in Angle Measurement

Abstract

Mechanical sensors for project and industrial processes are expensive as well as nonbiodegradable. Thus, the use of biodegradable and more economical materials for manufacturing of sensors has become a growing requirement. In this paper, we have proposed strain gauges made of cellulose acetate (paper) substrates with a constant gsm and compared their data for angle measurements. We have designed and manufactured two different sensors of varying length as well as conductor thickness with an organic substrate and correlated the sensor output with the corresponding industrial sensors and therefore determined that they can be used to obtain optimum outputs for smaller lengths of sensors.
