Determination of polarization in integrated piezoceramics by means of thermal waves and pulses
G. Gerlach
Aims
Evaluation of the polarization state of integrated piezoceramic modules concerning quantification and homogeneity as well as determination of interfacial defects inside the materials composite
- Thermal pulse method: pulsed laser will provide a higher heat power compared to LIMM and, consequently, a higher measuring signal
- study of structural components fabricated by the process chains of the CRC: structures with thick metal embeddings
- reduction of the measuring time for application in mass production
- determination of interfacial defects (such as lamination failures)
- structural components with integrated heater provide a condition monitoring of polarization and materials interconnection
Results
Model of pyroelectric current
- harmonically heated piezoelectric plate
- heat losses are characterized by single relaxation times tth or a continuous distribution of relaxation times
- In the case of a homogeneous polarization with p(z) = p0, we obtain [2]:

Thermal analysis with ANSYS:
- MFC actuator and aluminium die-casting: one-dimensional heat conduction is a suitable approximation, i.e., a reduction of complex structures to simple models is beneficial.
