Abstract
A piezoelectric membrane and a forming method thereof are provided, wherein the method of forming the piezoelectric membrane includes providing a porous substrate film, which is a membrane structure formed by a plurality of fibers and has two main surfaces. Then, piezoelectric material solution is permeated into the porous substrate film and then hardened, such that the fibers are partially covered with the piezoelectric material.
Claims25
A method of forming a piezoelectric membrane, comprising:
- providing a porous substrate film, which is a membrane structure with two main surfaces and formed by a plurality of fibers;
- permeating a piezoelectric material solution into the porous substrate film;
- and
- hardening the piezoelectric material solution so that the fibers are covered by a piezoelectric material, wherein the piezoelectric material comprises polyhexamethylene adipamide, poly(vinylidene fluoride) (PVDF), poly(vinylidenefluoride-trifluoroethylene) (P(VDF-TrFE)), or poly(L-lactic acid) (PLLA).
