Embodiment Construction
[0031] The present application will be further described in detail through specific embodiments below. The following examples only illustrate the present application further, and should not be construed as limiting the present application.
[0032] see figure 1 , the embodiment of the present invention provides an actuator 10 , which includes a first material layer 11 , a first electrode 12 , a second electrode 13 , an adhesive layer 14 , and a second material layer 15 . The first material layer 11, the adhesive layer 14, and the second material layer 15 have the same length and width, and they are laminated. The humidity expansion coefficient of the first material layer 11 is greater than that of the second material layer 15, and the first material layer 11 The coefficient of thermal expansion is smaller than that of the second material layer 15 .
[0033] The first material layer 11 is a carbon-based cellulose composite material layer. The cellulose material in the carbon...
