Abstract
A transparent resistive pressure sensor and method of making the same are disclosed. The transparent resistive pressure sensor may include a flexible pressure substrate, a pressure electrode layer, an elastic dielectric spacer with microstructure, a transparent pressure-sensitive composite layer composed of a transparent polymer dielectric matrix and a conductive one-dimensional nanomaterial oriented substantially in a thickness direction of the transparent pressure-sensitive composite layer, a support electrode layer, and a support substrate, where the elastic dielectric spacer with microstructure may include a transparent elastic dielectric film and a plurality of size-varied straight holes penetrating through the transparent elastic dielectric film in a thickness direction of the transparent elastic dielectric film.
