A new type of medical skin patch is developed that contains high-density, mushroom-like micropillars. Such dry-adhesive micropillars are highly biocompatible, have minimized side effects, and provide reasonable normal adhesion strength. To arrive at optimal conditions for the dry adhesive skin patch, the proper design of various structural and material parameters of micropillars is investigated.
