Abstract

Herein, we develop capacitive type strain sensors composed of the CNTs-PDMS nanocomposite thin films as electrodes and PDMS dielectric layer. The strain sensing performances of the strain sensors made of the flat and wavy structured electrodes are compared. Both types of strain sensors can measure strains up to 100%. We found that wavy structured based strain sensors possess higher sensitivity with quite stable and reliable responses due to the resistance stability and very low resistance standard deviation of the wavy structured electrodes. To illustrate the applicability of our strain sensors as flexible and wearable devices, we conducted the human motion detection by attaching the wavy structured strain sensors to the human body.
