Sensitive and stable strain sensors based on the wavy structured electrodes

Submitted by mortezaamjadi on Wed, 05/13/2015 - 09:40

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.

Silver nanowire (Ag NW) based transparent electrodes are inherently unstable to moist and chemically reactive environment. A remarkable stability improvement of the Ag NW network film against oxidizing and sulfurizing environment by local electrodeposition of Ni along Ag NWs is reported. The optical transmittance and electrical resistance of the Ni deposited Ag NW network film can be easily controlled by adjusting the morphology and thickness of the Ni shell layer.

The demand for flexible and wearable electronic devices is increasing due to their facile interaction with human body. Flexible, stretchable and wearable sensors can be easily mounted on clothing or directly attached onto the body. Especially, highly stretchable and sensitive strain sensors are needed for the human motion detection. Here, we report highly flexible, stretchable and sensitive strain sensors based on the nanocomposite of silver nanowire (AgNW) network and PDMS elastomer in the form of the sandwich structure (i.e., AgNW thin film embedded between two layers of PDMS).
