Braille touch screen device based on IPMC driving

The invention discloses a braille touch screen device based on IPMC driving. The braille touch screen device comprises at least one braille touch unit, wherein the braille touch unit is formed in such a manner that six contacts are packaged in three rows and two columns, and each contact comprises a support plate, a pair of electrodes, an IPMC driver, a VHB film and a cover plate; the support plate is a circular thin plate; the electrodes are annular electrode sheets with side ears and are arranged on the end part of the support plate; the IPMC driver is a circular sheet and comprises an edge constraint area close to the peripheral part and free areas of other parts, and the edge constraint area is arranged between the two annular electrode sheets; the VHB film is a circular film; the cover plate is an annular thin plate, the lower end of the cover plate is bonded to the VHB film, and the cover plate covers the IPMC driver; and the edge of the cover plate is pasted to the edge of the support plate, and the distance between the VHB film on the lower end of the cover plate and the support plate is not larger than the thickness sum of the two electrodes and the IPMC driver. The electro-mechanical coupling performance of the IPMC driver is utilized, and the braille touch screen device can be used for reading Braille and can also be used as a braille input device.
