Piezoelectric polymer microfiber‐based composite for the flexible ultra‐sensitive pressure sensor

This study presents a new type of composite consisting of piezoelectric poly(γ‐benzyl‐α, l ‐glutamate) (PBLG) polymer fibers, which contain a large dipole moment, and the elastomer polydimethylsiloxane (PDMS) as the matrix material. PBLG microfibers were fabricated and polarized using the electrospinning method and cast in PDMS to form a unidirectional continuous‐fiber composite. The PBLG/PDMS composite was characterized based on various aspects...
