Automated Measurement System for Characterization and Testing of Elastic Materials

In the case of testing materials or sensors sensitive to displacement or bending, a measurement system able to provide repeatable elastic deformation is needed. This paper presents an automated measurement system for the characterization and testing of sensors and elastic materials used within these sensors. The device under test will be repeatedly stretched or bent during tests. The range of the applied movement is 3 cm for this prototype. The frequency of the movement can be easily changed by changing the velocity or the deformation range. The necessary number of cycles can be programmed. The measurement setup consists of an automated measurement system, a power supply, and a digital oscilloscope.
