A strategy to evaluate the properties of circular ring dielectric actuators

摘要: Dielectric elastomer actuator can be used to adjust the properties of many optical elements. For example, place a diffractive transmission grating on center circular ring actuator. The deformation under voltage change period. is an annular dielectric elastormer coated with soft electrodes sandwiched between elastic circle and annulus. When subject voltage, active region will expand compress central as well outer compressive changes We study actuators based ideal model combined Arruda-Boyce hyperelastic constitutive law obtain relationship applied strategy presented here generic results may contribute use in devices.
