The significance of flexible and wearable electronic devices has been increased for mutual interaction communication with human body sensing and movement. One of the most important components in this devices is stretchable and flexible strain sensors that should be attached directly on flexible clothes. We report stretchable strain sensors that are composed of non-plied, plied and coiled stretchable Spandex fibers, which is coated with silver by an electroless plating technique. More specifically, the plied and coiled Spandex strain sensors exhibited a linear response in strain vs. electric resistance curve in the strain range up to 50% with a low-hysteresis behavior strain and the gauge factors were 20 and 15 respectively. Silver plated Spandex actuator simultaneous sensing which heat-operated. We verified that the electric resistance was increased while the actuator contracted with heating, and vice versa. |
