ELECTROACTIVE POLYMER ACTUATOR Russian patent published in 2016 - IPC H01L41/47 

FIELD: mechanisms.

SUBSTANCE: invention can be used for electroactive polymer actuators. Present invention consists in that actuator comprises an electroactive polymer layer, elastic electrode structure located on first side of an electroactive polymer layer, layer of counter electrode, arranged on second side of an electroactive polymer layer, andpassive layer, which is attached to the side of elastic electrode structure, passive layer forms a support layer for attaching actuator to substrate, elastic electrode structure has tangential modulus of elasticity Y_el, that is less than or almost equal to modulus of elasticity Y_EAP an electroactive polymer layer, and ratio Y_c/Y_EAP tangential modulus of elasticity of Y_c counter electrode layer and tangent modulus of elasticity Y_EAP of electroactive polymer layer is at least 10.

EFFECT: technical result is design of a mechanism with actuation mode to create relatively sharp edges without adding additional layers.
