Abstract
Developing a successful strategy to fabricate multifunctional sensors with high linear sensitivity is crucial for enhancing tactile interactions of the human body with the surrounding environment. Here, a stretchable multifunctional sensor consisting of stretchable porous film with multiscale aligned pores and Ag nanomesh electrode is reported. Due to the gradient in pore size and porosity inside the film, the sensor can detect bending and pressure simultaneously and independently as well as bending direction with quite high linear sensitivity up to 2 kPa. The 12 sensors are attached onto the tip and two joints each of four human fingers of one hand, and the capacitance changes measured by grabbing two different balls provide exact information associated with various hand gestures.
