Soft dielectric elastomer actuator for micropump application

摘要: This paper reports a miniaturized soft dielectric elastomer actuator targeted at an active flow controlled application. The muscle-alike buckles when subjected to pre-stretch tensile force by pull up spring that is made from 2 mm thick elastic plastic. forms out-of-plane deflection in conical frustum shape profile and couples with pair of diffuser elements rectify the fluid contraction expansion mode. To achieve desired deflection, finite element analysis deployed study geometrical design parameters. A maximum 0.42 noted 4.2 kV, where beyond this voltage, wrinkle formed on compliant electrode. dynamic response each repetitive actuation cycle achieves high reliability low operating frequency 0.1 Hz 0.25 standard deviation 1.4% 1.25%, respectively. dependent characteristic device determined measuring effective cycle. Experimental characterization fabricated micropump shows successful rate 42 μL/s optimum 3 Hz.
