Spreading deformable resistance-reducing surface of electroactive intelligent material and control method of spanwise deformable resistance-reducing surface

The invention discloses an electroactive intelligent material spanwise deformable resistance-reducing surface, which comprises a dielectric elastomer film and a flexible electrode layer, the middle part of the upper surface of the dielectric elastomer film is provided with straight micro ribs with the geometric dimensions of the cross sections of 2-20 microns in width, 10-100 microns in height and 20-200 microns in distance, and flexible electrode arrays are distributed on the two sides of the dielectric elastomer film. According to the spanwise deformable resistance-reducing surface of the electroactive intelligent material, the resistance-reducing surface is deformed in the spanwise direction through power-on and power-off of the flexible electrode array, and the spanwise spacing of the straight ribs can be changed (1), a sine structure can be formed (2), and the spacing can be changed at the same time and the sine structure can be formed (3). The beneficial effects of the invention are that the flexible el
