Sample holders for piezoelectric polymers and soft materials

aixACCT Systems and Electrosciences are joining forces in the field of piezoelectric polymer testing. This is the origin of the ESPY sample holder series, which allow the characterization of piezoelectric polymers as well as other piezoelectric materials such as membranes and fibers.

New Alliance for Polymer Testing

Markys G Cain, founder and CEO of Electrosciences Ltd., developed the prototype of the d31/d32 tester for polymer and other soft piezo materials characterisation. His next step was to find a partner that could make the system ready for series production and bring it to market. We are delighted that Markys thought of aixACCT Systems right away.

  • Our base system for measuring d31/d32 coefficients of piezoelectric polymers

    The ESPY31 enables quick and precise measurement of the piezoelectric coefficients d31 and d32 of piezoelectric polymer films or other soft piezoelectric materials such as fibres or membranes. It contains an integrated force measurement cell to precisely monitor static and dynamic mechanical stress. The ESPY31 is a highly sensitive measuring device that can also be used to measure other electric properties, like P-E hysteresis or capacitance. Environmental conditions can be monitored with the build-in temperature and humidity sensor enabling precise studies on material properties.

          • Our measurement tool for the investigation of the d33 coefficient of piezoelectric polymers.

            The ESPY33 provides a direct and indirect measurement of the piezoelectric constant for a variety of piezo materials.  It is based on  technologies which enable fast and accurate measurement of piezoelectric constant d33 – a fundamental piezoelectric material property.

            What this means for you:

            • Accurate and reliable test data to support accelerated materials development
            • Reducing costs for material, device and systems development
            • Provides a traceable measurement of a materials piezoelectric coefficient

            The ESPY33 will be launched soon!
