Embodiment Construction

[0041] The claims define an actuator arrangement comprising: an actuation structure capable of providing actuation based on the presence of an optically responsive portion deformable when it receives actuating light; and a light guide layer, ie a light guide for guiding the actuation light and providing the actuation light to the photoresponsive layer. The actuation structure is configured such that the light-responsive portion is more efficiently illuminated and incorporated in the actuation structure than the light-responsive portion of the same volume. Thus, an improved actuation output (stroke and / or strain) may be obtained with a specific volume of the light-responsive portion.

[0042] Although layers closer to the light source will be deformed to a greater extent than those further away due to the attenuation of light as it progressively passes through more layers, a deformable non-photoresponsive layer (light-guiding layer) is provided. , which separate adjacent photo...

Abstract

An actuator device comprises a stack formed from a plurality of photoresponsive layers, which deform in response to light, which are partitioned by respective deformable non-photoresponsive layers. The deformable non-photoresponsive layers guide light between and to the photoresponsive layers, and can follow the deformation of the photoresponsive layers.

Description

technical field [0001] The invention relates to a device with an actuator actuatable by light. The invention also relates to an actuation method and a manufacturing method. Background technique [0002] Electroactive materials that convert electrical energy into mechanical action have been investigated for a variety of applications. However, such materials may require relatively high voltages, which may prevent their use in certain applications, such as in devices to be used in or near the body. Catheter steering and 'soft robotics' (eg to help move a patient's clothing) may require high voltages, but using such high voltages in or close to a patient's body raises electrical safety concerns. [0003] Light-responsive actuators have been developed that are able to convert light into mechanical action. Photoresponsive materials may consist of films or nano- or micron-sized particles. See eg US20080258108, US20090069528, JP2008-228368 or US20120175520. Such materials may c...
