Large Displacement in Relaxor Ferroelectric Terpolymer Blend Derived Actuators Using Al Electrode for Braille Displays
Poly(vinylidene fluoride) (PVDF) based polymers are attractive for applications for artificial muscles, high energy density storage devices etc. Recently these polymers have been found great potential for being used as actuators for refreshable full-page Braille displays for visually impaired people in terms of light weight, miniaturized size, and larger displacement, compared with currently us...
متن کاملEAP actuators aid the quest for the "Holy Braille" of tactile displays
The authors present the worldwide need for electronic Braille displays to promote literacy among the blind. The use of of EAP's to produce Braille displays is encouraged and detailed descriptions of the technology of Braille are presented. Prior art is covered since the early 1950's through present day displays based mostly on piezoelectric technologies. EAP's offer the promise of the “Holy Bra...
متن کاملDesigning Effective Refreshable Braille Displays
It’s been shown that non–visually impaired readers comprehend text better when they actively read it rather than passively listen to it. Active modes of processing text such as reading braille—instead of more passive modes like speech—would likely confer a similar advantage to visually impaired readers, particularly for material that’s highly technical or that requires spatial processing, such ...
متن کاملLibbraille: A Portable Library to Easily Access Braille Displays
The TiM project intends to develop and to adapt computer games for visually impaired children. In order to achieve this project a library which allows to easily access Braille displays was developed. This library provides all the functions needed to write text on the Braille display, directly raise Braille dots as well as receive the keys pressed on it. On top of that this library works with ma...
متن کاملControl of soft machines using actuators operated by a Braille display.
One strategy for actuating soft machines (e.g., tentacles, grippers, and simple walkers) uses pneumatic inflation of networks of small channels in an elastomeric material. Although the management of a few pneumatic inputs and valves to control pressurized gas is straightforward, the fabrication and operation of manifolds containing many (>50) independent valves is an unsolved problem. Complex p...
