Abstract

We present a flexible pressure sensor based on vertically aligned carbon nanotube (VACNT) carpets on polydimethylsiloxane (PDMS) substrate. The device was fabricated using the partial-embedding of VACNTs in PDMS, which enables the stretchable and flexible device, which maintains consistent electrical resistance with a high level of structural integrity under various strain conditions. The pressure was read measured under an applied pressure applied orthogonally to the sensor. The sensor output under a constant applied pressure was unchanged while applying up to 40% lateral stretching and 180° bending, demonstrating a reliable pressure reading independent of lateral stretching or bending.
