We propose a sandwich-type resistive pressure sensor based on electrospun elastomeric nanofiberssilver nanoparticles process.  We have successfully applied to smart switchespulse sensing. We observed that smart switches combined with LEDsclothing still retain performance. Pulse sensing monitors real-time beats in normal adults.

By adjusting the parameters of the electrospun nanofiber, the sensing sensitivity of at least 0.2 kPa can be achieved,the on-resistance value is less than 10 Ω. By controlling the density of the electrospun nanofibers, several different ranges of pressure sensing intervals were obtained, which remained stable after the cyclic test of strain (strain ε = 0.5)bending (curvature 1 / 3 mm -1 

We have successfully combined smart switches with LEDsapparel to maintain their performance. Pulse sensing instantly monitors the number of heartbeats in normal adults. It is expected to be widely usedcommercialized in various tactile electronic devices that interact with the human body in the future.
