Size-dependent piezoelectric and mechanical properties of electrospun P(VDF-TrFE) nanofibers for enhanced energy harvesting

Dimensional reduction of electrospun P(VDF-TrFE) increases crystallinity (DOC), electroactive phase content (EA), Young’s modulus (<italic>E</italic>) and piezoelectric coefficient (<italic>d</italic>₃₃), collectively leading to enhanced piezoelectric energy harvesting efficiency.
