Technique: High Precision, Piezoelectric d33 Testing System

Acquisition year: 2019

Contact person (Joanneum Research): Barbara Stadlober (barbara.stadlober@joanneum.at)

Responsible: Martin Zirkl  (martin.zirkl@joanneum.at)

Description:

The system works by clamping the sample, and subjecting it to a low frequency force. Processing of the electrical signals from the sample, and comparison with a built-in reference, enables the system to give a direct reading of d33 – one of the most useful parameters in evaluating the material. This is a material coefficient representing charge per unit force in the direction of polarisation.

Specifications:

Applications & Features:

  • Assessment and Quality Control
  • Research and Development
  • All systems directly measure d33
  • PC-Driven or stand-alone operation
  • Direct readings for almost any shape and size

Sample Size Maximum dimensions:

  • 50 mm in polarisation direction.
  • 68 mm perpendicular (i.e. maximum diameter of a symmetrically supported disc is 136 mm)

Maximum sample mass:

  • 1 Kg with standard suspension.

Different suspension mechanisms can be provided to special order for more massive samples or very thin or soft samples.
