An instrumented electromechanical apparatus for mechanical characterization of human hand palm soft tissue

Our hands perform different actions from extremely delicate and accurate actions to heavy labor. While several studies have been conducted for mechanical characterization of different biological tissues, only little information is available on the mechanical properties of human hand palm. In this paper electromechanical apparatus is introduced for mechanical testing of human hand palm based on flat punch indentation approach. The proposed system has capabilities of performing different mechanical experiment procedures such as compression, tensile, stress relaxation and indentation. The flat punch hand palm indentation experiments conducted on twenty objects. The experimental data are fitted to well-known viscoelastic rheological models including double Maxwell-whichert (DMW) and triple maxwell-wichert (TMW) models.
