ANALYSIS OF PARAFFIN WAX ACTUATOR FOR FUTURE INCORPORATION IN A BRAILLE ACTIVE DOT
This paper proposes to analyze paraffin wax actuator for future utilization as an actuation element for refreshable Braille dots. The paraffin is used as phase change material (PCM) for thermal energy transformation in linear work. The efficiency of a PCM is dependent on the encapsulated quantity and energy storage capacity per mass unit during its melting and solidification process. The investigation on the performance of PCM’s for future incorporation into a Braille device actuator is performed in this paper.Key words: phase change material, paraffin wax, solid-liquid state, Braille dot, analysis, thermal actuator
