Abstract :
We present a stretchable and multifunctional capacitive sensor made of gold thin films embedded in silicone rubber. The mechanical compliance of the gold films and silicone membranes allow the device to be bent, folded, or stretched without damage, making it a suitable candidate for electronic skin applications. The device can detect strains up to 20%, human touch, and pressure up to 160 kPa, and reliably function when it is held stretched or relaxed.
