Designing a Highly Sensitive Printed Strain Sensor Array with Microstrain Detection

This work presents a comprehensive exploration of printed strain sensor array fabrication encompassing selection of substrate material, sensing layer deposition, design and fabrication of the sensor array, and the electronic component used to obtain sensor output. The objective of this study is to design a strain sensor array that exhibits highest sensitivity against bending conditions without degradation. Three distinct designs of resistance element arrays were tested rigorously to identify the most suitable sensor for application involving repetitive bending conditions such as respiration monitoring.
