The significance of flexible and wearable electronic devices has increased for mutual communication with the motion of human body. In this study, we report a large-deformable polymer strain sensor, which is composed of plied Spandex fibers with a silver thin film on the Spandex fiber about 100 nm thickness by the electroless plating technique. When the silver-plated Spandex fibers are stretched, cracks in the silver thin film are generated and the gap of the cracks widens as the strain increases. The electrical resistance of silver-plated Spandex fibers is changed by the gap. The Spandex strain sensors exhibited a linear response in strain vs. electric resistance curve. We demonstrate the applicability of our reliable strain sensor made from commercial fibers might be used as wearable devices imbedded in sportswear, patient gown, etc. |
