Kirigami-patterned PVDF piezoelectric harvesters

Reanalysis showed Kirigami significantly improves d31 output with no measurable d33 effect.

Constraint

PVDF harvesters need higher d31 output without sacrificing other modes.

Built

Kirigami-patterned samples, two custom rigs, and thermal testing at UNC Charlotte.

Happened

Kirigami improves d31 with no measurable d33 effect after reanalysis.
