| Zusammenfassung | In ferroelectric materials, the coupling between thermal, electrical and mechanical properties is responsible for piezoelectric, pyroelectric and electrocaloric effects and thermal expansion. This multifunctional coupling is responsible for their wide range of technological applications as actuators, sensors, energy harvesting devices, thermal detectors and novel solid state coolers. To improve the efficiency and reliability in automotive, energy, process, electronics and medical industries new functional materials are being developed which operate at elevated temperatures up to 1000 °C. Reliable, accurate and traceable measurement of electro-thermo-mechanical coupling at high temperatures is essential to provide the data required for the development of new materials technology, and reliability in characterisation. A cooperation of European metrology institutes aims to develop the facilities for the traceable metrology of coupling between thermal, mechanical and electrical properties in new materials technologies at high temperatures and high electric fields. To unravel the thermoelastic and electromechanical couplings, PTB conducts high-accuracy piezoelectric strain measurements within a temperature range from room temperature to 200 °C. This is achieved by full-optical-field multiwavelength interferometry. To extend the capabilities of the current setup, a heatable sample environment with high-voltage functionality is being developed. |
