Method for manufacturing an electroactive actuator
First Claim
1. A method for manufacturing an electroactive actuator from a stack comprising at least one first electrode and at least one layer comprising an electroactive polymer superposed on the at least one first electrode, with the at least one electroactive polymer having the capacity to respond by a displacement when the electroactive polymer is in a crystalline state and when an electric field is applied thereto, the method comprising:
- obtaining an electroactive layer by crystallizing the at least one electroactive polymer of a layer of the at least one electroactive polymer superposed on the stack; and
forming at least one second electrode such that the electroactive layer is disposed between the at least one first electrode and the at least one second electrodes;
wherein;
the electroactive polymer is formed of a material able to crystallise at least partially under the effect of an exposure to the ultra-violet (UV) radiation; and
the crystallizing comprises exposing the electroactive layer to ultra-violet radiation during which a portion at least of the ultra-violet radiation is delivered in the form of one or several pulses, with the duration of each pulse being less than 100 milliseconds (ms) (10−
3 seconds).

Abstract
A method for manufacturing an electroactive actuator is provided. The method includes applying a layer of an electroactive polymer to an electrode surface, crystallizing the electroactive polymer by application of U.V. flash and applying a second electrode onto the crystallized electroactive polymer layer. According to the method a stack of multiple superimposed first electrode layers, electroactive polymer layers and second electrode layers may be obtained.
