The original aixCMA test bench for ceramic multilayer actuator characterization has been extended by a temperature control unit which allows now to perform all measurements in the temperature range from room temperature up to 200°C. This system has been developed by aixACCT Systems to fulfill customers requests for system solutions. It includes a unique sample holder for a wide range of different sized actuator devices, necessary amplifiers for excitation voltage and current response measurements, aixACCT´s advanced measurement software, and optional software tools for data analysis and data exchange with database management systems.

The aixCMA system offers comprehensive electrical and electro-mechanical characterization of ceramic multilayer actuator devices for device qualification and production control. Important actuator characteristics like blocking force diagram and actuator stiffness can be derived for a wide temperature range. Special user defined excitation waveforms for electrical and mechanical load allow investigations of the CMAs performance under real application conditions.

Application

• Blocking force and actuator stiffness measurements
• Large and small signal electrical and piezoelectric measurements
