To introduce students to mechanical testing methods in a clear and practical way, the Computer-Aided Biomechanics research group at the Institute for Lightweight Construction and Structural Biomechanics, led by Univ. Prof. Dr. Dieter Pahr, developed and designed a mechanical tensile-compression testing device, which was then built by Robert Exler in a small series of 15 units. The Arduino-based testing system allows users to manually test various materials while directly experiencing force, deformation, and material behavior. Through manual operation, users can physically feel the forces at work during testing—an important step toward not only understanding technology theoretically but truly grasping it.
The measurement data can be transferred via USB to a standard PC and subsequently analyzed. In this way, the system combines hands-on experience with digital data acquisition and analysis. The goal is to provide technology enthusiasts and students with tangible access to materials testing, design, sensor technology, additive manufacturing, and measurement technology—and to foster a lasting fascination with technology. In addition, the plan is to make the concept accessible enough that interested individuals can build the testing setup themselves if needed.
Starting in the winter semester of 2026, the in-house developed testing setups will be used in teaching.
