Tensile Elasticity and Stiffness Measurements

Using instron device we have conducted Quasistic uniaxial tensile test. To measure the tensile elasticity we have calculated the Young’s Modulus of the prototypes that we have made and conducted electromechanical tests which we will explain in details in following section. The final sensors with the best performance in terms of self-generated electrical signals from linear motor testing have the Young’s Modulus equal to 0.363 and 0.0467 Megapascals . The softest which its fabrication process is illustrated here has 0.363 MPa tensile elasticity.

Elasticity measurement :Two solutions composed of different proportions of silicone elastomer to PDMS exhibit different elasticities. The Young’s Modulus value (measure of elasticity/stiffness) for each is derived from the gradient of the plots in the figure above.

To measure elasticity of sensors we have conducted Instron testing. The softer prototype perform better than stiffer one in terms of electrical output. By different proportions of silicone elastomer to PDMS, solution exhibit different elasticities. The Young’s Modulus value (measure of elasticity/stiffness) for each is derived from the gradient of the plots in the figure above.
