EXTENDED ABSTRACT: With the continuous advancement of the information age, the Internet of Things demands higher standards on intelligent sensor devices. Sensors based on piezoelectric materials are intelligent devices that integrate signal sensing and energy collection, and are widely used in fields such as intelligent energy, consumer electronics, and bionic medicine [1]. The present work reported the performance breakthrough of bottleneck of existing biocompatible piezoelectric material polylactic acid by macromolecule construction method based on carbon-oxygen dipoles and flexible segments. In addition, a high-throughput plasma polarization system and a high-throughput non-destructive piezoelectric coefficient d33 testing system were developed, which effectively improves the polarization efficiency, shortening the detection time, supporting the efficient screening and large-scale preparation of piezoelectric materials, and significantly improving the piezoelectricity ofbiocompatible polylactic acid materials. On this basis, a series of highly elastic piezoelectric polymers and piezoelectric sensor devices were prepared, which are applied in energy safety fields as LIBs temperature/pressure monitoring sensing modulus, the commercial electronic fields as simultaneous pressure touch and gesture recognition functional modulus on display devices, and the medical field as stimulated repairing/functional monitoring modulus.
