Papers by Keyword: Acrylic Elastomer

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.

Abstract: The power generation characteristics of electroactive acrylic elastomer (EAE) were studied by experiments based on theoretical analysis. The generator mode theory fundamentals of EAE were discussed and studied. A power conversion control system for EAE was designed. The experimental results show that energy generated as nearly incompressible elastomer layers increase in area and decrease in thickness when EAE stretched, and power generated when EAE relaxed. The voltage of generation increased with the bias voltage increasing. The experimental results accorded with analytical model and lay the foundation for generator of EAE.
