Direct Piezoelectric Coefficient Measurements of PVDF and PLLA under Controlled Strain and Stress

Open-circuit direct piezoelectric coefficients g31 of bi-axially stretched PVDF and chiral PLLA are reported. This measure is decisive for sensor, generator and energy harvesting applications. We use an in-situ method with contactless voltage measurement during a conventional tensile-test, greatly i...
