In this contribution, a novel mechanical interface design for multilayer DE stack transducers is presented and compared with alternative connecting approaches. As mechanical interfaces have an impact on the effective actuator performance, an optimized design approach, using a combination of sliding surfaces and hydrostatic power transmission, is proposed. Based on this, an optimized interface design for stack-transducers is carried out and conducting simulations and experiments are performed to investigate the improvement of the static actuation performance.
