Problems solved by technology

However, traditional actuators are fragile, require external power, and cannot sense and feedback control conditions, making them unable to meet operational tasks in high-precision and complex environments such as medical operations, disaster rescue, and industrial grasping.
An active mount with moving magnet electromagnetic actuator (Patent No.: CN110425241A), mentions a magnetically controlled actuator, but it does not have the function of sensory feedback adjustment; a bionic sensory actuator The flexible actuator and its preparation method (Patent No.: CN109866480A) adopted the biological structure imitating the scorpion to solve the self-sensing problem of the actuator, but what the actuator used was an ionic polymer-metal composite (IPMC ), and ionic polymer-metal composites are often difficult to maintain consistency in surface capacitance and electromotive properties due to process differences during the preparation process. After the actuator is made, it needs a more complicated control system and feedback to adjust performance
[0003] In addition, after the actuator works for a long time in the above-mentioned complex environment, its actuating surface is often contaminated with dust and oil, causing problems such as uncontrollable friction, surface deformity and even damage when it is actuating and doing work.

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a sensing-actuating actuator material with self-cleaning function and a preparation method and application thereof. Background technique [0002] Actuator is a key component to implement active control and an important part of active control system. The role of the actuator is to exert control force on the control object according to the determined control law. However, traditional actuators are easily damaged, require external power, and cannot sense and feedback control conditions, making them unable to meet operational tasks in high-precision and complex environments such as medical operations, disaster rescue, and industrial grabbing. An active suspension actuated by a moving magnet electromagnetic actuator (Patent No.: CN110425241A), which mentions a magnetic control actuator, but it does not have the function of sensing feedback adjustment; a bionic sensing a...
