Flexible, Stretchable and Weavable Piezoelectric Fiber

Abstract

The flexible piezoelectric fibers can be stretched to a tensile strain of 5% and can generate over 50 μW·cm−3.The FPFs are sufficiently robust for knotting, sewing and weaving and can also be converting to piezoelectric coils by twist insertion. These spring-like coils can be reversibly stretched to 50% strain without failure.
