Smart Refreshable Braille Display Device Based on Magneto‐Resistive Composite with Triple Shape Memory
Source abstract
Abstract
Abstract Braille devices made from stimuli‐active polymers have provided a new approach for obtaining information on Braille text. However, it is still essential to find a more convenient and effective method to develop multifunctional Braille devices with shape memory effects to broaden their applications. Here, a novel smart refreshable Braille display based on triple‐shape memory and magnetoresistive composite is developed with the advantages of simple fabrication, multifunctionality, and harmlessness for blind people. The triple shape memory effect enables this device to record the Braille text information and display the text using a complex Braille dot array. The stimuli‐dependent conductivity produces a simultaneous electrical sensing signal when Braille dots are touched, thus the reading areas can be distinguished. Therefore, this multifunctional flexible composite has the potential to realize a refreshable and portable Braille e‐book in the future.
