Abstract
Advancements in technology are creating demands for flexibility and bio-degradability. Herein we present a very economical and easily fabricated wearable strain sensor. The anticipated flexible strain sensor is a non-toxic, eco-friendly, and bio-degradable invention. A very easy approach and commercially available materials i.e., copper tape and printing paper are used to fabricate the proposed strain sensor. The anticipated work offers a quick response time of 0.59 sec along with defined tolerance to differentiate between the flat and bent states. For off-body and on-body analysis tolerances achieved are 20 pF and 30 pF, respectively. The intended strain sensor is quite sensitive as it can detect 0.18% of strain very efficiently. It exhibits a sensitivity factor (GF) value of approximately 683. The sensor undergoes real-time monitoring of joint movement. The proposed strain sensor having features of flexibility and Eco friendliness proves itself a apt candidate for diversified wearable applications.
