Abstract

Piezoelectric compositions are provided wherein mechanical and piezoelectric properties can be separately modulated. Preferred compositions include resin blends that comprise: (a) a piezoelectrically active polymer and (b) a matrix polymer, methods of making, and use of such resin blends. Advantages of preferred resin blends of the invention can include high piezoelectricity, mechanical strength and flexibility, convenient fabrication process, and high sensitivity at high temperatures.
