The characterization process of micro- and submicrometre particles in some cases demands their careful handling and placement. In most cases, a well-designed microgripper can address these requirements. The following research is focused on the process of design, finite element analysis, and microfabrication of an innovative compliant constant-force microgripper. This new architecture enables microgripper to handle microcomponents under constant gripping force without using any force control system. This characteristic makes it outstanding in compare to the previous works in literature. The adopted fabrication process is a ultraviolet-assisted vertical etching on polyethylene terephthalate substrate. This process is a well-established process to offer the requirements of high resolution and high aspect ratio in microfabrication of plastic structures. The prototyped sample has been successfully tested and its performance during micro-assembly process has been verified.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
