Finite Element Analysis on the Mechanism of Human Tactile Sensation in Comparing Different Material Properties and Thickness

Abstract:

The capability of humans mechanoreceptor in distinguishing the characteristic of surrounding objects is a very tremendous skill. For this study, the objective here is to simulate on the reception of SA1 mechanoreceptor unit in differentiating variety of thickness for two type of material, which is Stainless Steel and Copper. By utilizing Catia as the main tool, the design process and FEA simulation has been performed. Evaluation point has been specified from the simulation data in order to perform a more detailed analysis. As a result, the Von Mises criteria (detected by the skin) for Stainless Steel is higher than Copper. Also, the variation in detected stress reduces when the thickness of specimen is exceeds 0.1mm. This supports the theory, on the main role of SA1 unit in determining various thickness of materials.
