“…Hyperelastic materials are structural materials of many electromechanical systems such as actuators, sensors, and energy harvesters. More specifically, hyperelastic materials have been widely used for electro-active-based systems [ 22 , 23 , 24 , 25 ]. Up to now, hyperelastic materials have been designed in different geometries, e.g., beams [ 26 , 27 , 28 , 29 ], plates [ 30 , 31 ], and shells [ 32 , 33 ].…”
