▎ 摘　　要

NOVELTY - A piezoelectric sensor comprises graphene, polyvinylidene fluoride nanofiber covered with graphene/elastic fiber and elastic fibers coated with graphene. USE - Piezoelectric sensor is useful for monitoring the dynamic deformation signal. ADVANTAGE - The piezoelectric sensor can be simply manufactured with stable mechanical performance, high flexibility and improved cycle stability and can accurately and sensitively monitor the dynamic deformation signal without the need of additional power supply support. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the method for manufacturing the piezoelectric sensor.
