Testing Function
The piezoelectric coefficient d33 defines the electromechanical coupling strength between mechanical force and electric displacement. Utilizing the direct traceability method, our calibrated PEAL-1000 system applies dynamic low-frequency mechanical stress and measures the generated charge with precision electrometry. We provide accredited characterization of d33 (longitudinal), d31 (transverse), and d15 (shear) across ceramics, single crystals, polymers, and electrospun membranes.
