A Novel Concept of a Braille Device Based on Wax Paraffin Actuator

摘要

The aim of this paper is to investigate and de velop a novel refreshable Braille device actuated by thermal actuators based of phase change transformation material. The paper starts with a short introduction about some representa tive tactile devices, the importance of those devices into society, and highlighting the author's previous work in the field. Sec ond paragraph presents the proposed design of a Braille cell, third paragraph discuss aspects regarding the thermal analysis of the proposed model along with numerical results. Forth paragraph deals with the presentation of the developed prototype along with results from the conducted test of its performances.
