Short summary
Piezoelectric devices are characterized non-destructively to ensure their functionality. The material is heated by laser diodes. The resulting temperature changes lead to a pyroelectric current. Analytical and numerical finite element models describe the temperature distribution and the current in frequency and time domain. Modelling and experimental results are compared for piezoelectric plates and integrated sensors and actuators.
