Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] Please also see Figure 1-Figure 5 , the present invention provides some embodiments of a biomimetic sensory-execution integrated flexible actuator.

[0033] Using receptors to perceive signals is a unique way of perception in living things. These receptors are usually coupled with structures and materials, with fine structures and materials that are both rigid and flexible. In addition, different from the response stimulus source of the existing stimulus-response actuators, quite a few organisms rely on vibration signals to perceive the external environment, that is, vibration s...

Abstract

The invention discloses a bionic sensing and executing integrated flexible actuator and a preparation method thereof. The flexible actuator comprises an ionic polymer metal composite (IPMC) actuatinglayer, an adhesive layer arranged on the IPMC actuating layer, and a bionic strain sensing element arranged on the adhesive layer; the bionic strain sensing element comprises a flexible substrate layer arranged on the IPMC actuating layer, a conductive layer arranged on the flexible substrate layer and a first electrode arranged on the conductive layer, wherein the flexible substrate layer is provided with bionic V-shaped groove arrays. When external vibration waves are transmitted to the bionic strain sensing element, and output resistance of the bionic strain sensing element reaches a presetvalue, the IPMC actuating layer is automatically started, actuating bending occurs, and the bionic strain sensing element layer is further driven to deform. The actuating degree of the actuator can be indirectly acquired according to an output resistance value, so that the purposes that sensing and executing are integrated and actuation is intelligent and controllable are achieved.

Description

technical field [0001] The invention relates to the field of actuators, in particular to a bionic perception-execution integrated flexible actuator and a preparation method thereof. Background technique [0002] In recent years, researchers have developed a variety of actuators, which can be driven by external stimuli such as electricity, heat, light or humidity to produce deformation. However, most of the actuators reported so far only rely on the properties of smart materials to perceive environmental information and achieve actuation effects. This kind of actuator, which relies on the properties of smart materials to perceive environmental information and realize actuation, not only cannot intelligently recognize signals, but also cannot make intelligent and controllable execution behaviors according to environmental signals. From the perspective of bionics, this is also contrary to the way living things take from perception to execution. Higher organisms perceive exter...
