• We developed a hydraulic amplification mechanism (HDAM) for applications requiring large deformation. HDAM consists of a set of two largely deformable polydimethylsiloxane (PDMS) that are sharing a closed fluid chamber filled with glycerin, an incompressible fluid. Chamber's geometry with input and output surfaces having different cross-sectional areas creates amplification. By varying and studying influence of geometry on amplification performance, we achieved a mechanism offering displacement amplification up to 18-fold for static actuation. For tactile display application, by combining HDAM with piezoelectric actuators, we can amplify the input displacement generated and use the output displacement to stimulate tactile receptors. For such applications, dynamic characteristics are essential so we studied dynamic response of HDAM when combined with piezoelectric actuators.
