Abstract
Bio-compatible high stretchable strain sensors can be applied in several areas ranging from engineering to medicine. Among many efforts in developing new sensors, there is a growing demand for eco-friendly devices characterized by a minimum environmental impact and a low cost. This work deals with the development and analysis of a biocompatible, eco-friendly, and unexpensive strain sensor, easily manufacturable, consisting of natural coconut oil, and recycled char, the solid residue obtained after the gasification of biomass. The results demonstrate an average gauge factor of (23.2 ± 2.5), with a linear response until 80% strain, a higher hysteresis occurring between strain values of 25% 40% and a stable and reliable response after 250 stretch/release cycles.
