TRIBOTOUCH Hand Abrasion Tester
Home > Testing and Analysis > TRIBOTOUCH Hand Abrasion Tester
The TRIBOTOUCH hand abrasion tester is designed to perform real life testing of finished products or lab samples in respect of resistance to hand abrasion. The TRIBOTOUCH is set-up to exactly reproduce the complex chemomechanical system of human hand abrasion according to international standards. The flexible design of the TRIBOTOUCH allows various mechanical and chemical options.
The state of the art design of the TRIBOTOUCH produces highly reproducible results. The motion of the piston (artificial finger) is electronically controlled to ensure repeatability. The selected components of the TRIBOTOUCH guarantee high reliability by low maintenance.
When humans touch a surface they expect a feedback. Our fingers are not sensitive in regards of pressure, however they are very sensitive for shear and friction. Therefore, when we need feedback from a surface we always perform a sliding motion by touching a surface.
The TRIBOTOUCH exactly reproduces the act of a human touch on the surface. The piston moves with an 45° angle and normed speed onto the surface. After touching the surface the piston slides a predefined distance along the surface.
The human hand consists of a visco elastic material containing a rough and structured surface. The visco-elasticity of the finger is reproduced by a silicone material, the structure of the skin is simulated by a normed cotton textile. In addition, sweat or hand cream can be added to create a severe chemical environment.
