Piezoelectric bimorphs have been used as a micro-gripper in many applications, but the system might be complex and the response performance might not have been fully characterized. In this study the dynamic characteristics of bending piezoelectric bimorphs actuators were theoretically and experimentally investigated for micro-gripping applications in terms of deflection along the length, transi...

<p class="Abstract"><span lang="EN-US">The functional characterization of MEMS devices is relevant today since it aims at verifying the behavior these devices, as well improving their design. In this regard, study focused on a microgripper prototype suitable in biomedical applications: measurement angular displacement comb-drive carried out by means two novel automatic procedures, b...

In this paper, the prototyping of a new piezoresistive microforce sensor is presented. An original design taking advantage on both mechanical and bulk piezoresistive properties of silicon is presented and enables to easily fabricate a very small, large range, high sensitivity with high integration potential sensor. The sensor is made of two silicon strain gages for which widespread and known mi...

Smart materials have been widely used for control actuation. A robotic hand can be equipped with artificial tendons and sensors for the operation of its various joints, mimicking human hand motions. The motors in the robotic hand could be replaced with novel electroactive polymer (EAP) actuators. In the three-finger gripper proposed in this paper, each finger can be actuated individually so tha...
