In high-tech companies operating worldwide innovation is the key driver for long-term market success. Hence, innovative engineering technologies not only provide technological challenges but also investment risks for decision makers who want to tread new paths in product development. As an important example, the typically required high operating voltage and the need for high voltage power supplies constitute physical, economic and psychological restrictions for the application of dielectric elastomer actuators (DEA). Therefore, based on the view of product integration we aimed to limit the applied voltage below 600 V. To achieve this goal, we developed membrane actuators made of dielectric elastomers, which can be driven by lower voltages provided by low-cost power supplies. In detail, a particular device was developed with specially designed compression fittings clamping the DEA-film which enabling a simple electric contact between the actuator and the circuit board. The prefabricated actuator module was integrated in a fast switching, low-cost electronic circuit board. The power supply generates up to 550 V with a slew rate of a few microseconds, whereas the whole circuit has the geometrical dimension of a credit card. A plunger connected to the DEA-film moves out of plane when the actuator is activated. With the use of permanent magnets, interacting with the plunger, the system can be enhanced to meet industrial requirements in force and stroke. The resulting 'embedded' system offers a platform for further applications in different industrial segments and applications for instance in automation with valves, grippers or micro pumps in process automation and life sciences.
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.
