Problems solved by technology

However, because the above-mentioned electric actuator material adopts a metal structure, its flexibility is poor, resulting in a slow thermal response speed of the entire electrothermal actuator, which is not conducive to the application in actual production and life.
[0004] In particular, most of the traditional actuators are opaque, which is not conducive to the observer to observe the specific movement of the object manipulated by the actuator from the outside in the actual application of the actuator. In addition, in the all-solid-state zoom lens, tactile display and other fields also require the use of transparent actuators

Description

technical field [0001] The invention relates to the field of electric actuation materials, in particular to a transparent electric actuation material and a transparent electric actuator thereof. Background technique [0002] The working principle of the actuator is to convert other energy into mechanical energy. There are three ways to achieve this conversion: through electrostatic field into electrostatic force, that is, electrostatic drive; through electromagnetic field into magnetic force, that is, magnetic drive; using materials Thermal expansion or other thermal properties effect the conversion of energy, ie thermal actuation. [0003] The traditional electrothermal actuator uses two pieces of metal with different thermal expansion coefficients to form a double-layer structure as the electrostrictive element. When the current is applied to heat, because the thermal expansion of one piece of metal is greater than that of the other, the bimetallic piece will expand in the...
