AI Technical Summary
Existing PVDF materials have poor mechanical properties in wearable flexible piezoelectric sensors, making it difficult to simultaneously satisfy excellent piezoelectric and mechanical properties.
PVDF/Ca-POM composite fiber membranes were prepared by electrochemical spinning, utilizing the high flexibility and high aspect ratio of Ca-POM to form a double network structure, thereby improving the conformation of PVDF chains and the β phase content, and enhancing mechanical and piezoelectric properties.
The mechanical and piezoelectric properties of the PVDF/Ca-POM composite fiber membrane were improved, with a piezoelectric constant (d33) of 93.63 pm/V, a Young's modulus of 3.0 MPa, and an elongation of 88%, which is consistent with human skin and is suitable for wearable flexible piezoelectric sensors.
