Preparation and Performance of Bubble-Type Actuator for Braille Display

Abstract:

Technology involved in braille display for blind or visually impaired people plays an important role as typical paper form of braille cannot be changed whereas display form of braille can be done at any time. Dielectric elastomers (DEs) are electroactive polymers with low elastic stiffness and elongation, with high dielectric constant have been found for actuator application. In the present study, we have used acrylic elastomer to manufacture a bubble-type actuator and its deformation was examined with increasing electrical field to find its suitability to use as a braille.
