Elastic and viscoelastic characterization of microcapsules for drug delivery using a force-feedback MEMS microgripper

This paper reports a monolithic, force-feedback MEMS (microelectomechanical systems) microgripper and its application to micro-scale compression testing of swollen hydrogel microcapsules at wet state during manipulation. The single-chip microgripper integrates an electrothermal microactuator and two...
