Touch sensor with enhanced and small-scale sensitivity and method for making same
A touch sensor with enhanced and small-scale sensitivity includes a substrate, a piezoelectric layer on the substrate, a first electrode layer between the substrate and the piezoelectric layer, a second electrode layer on the piezoelectric layer, and an outer touch layer. The touch layer is made of flexible and deformable material. The touch layer includes a base layer covering the second electrode layer and finely-shaped protrusions protruding from a surface of the base layer away from the piezoelectric layer. The base layer and the protrusions are integrally formed. The disclosure also provides a method for making such touch sensor.
