Improving design of piezoelectric braille cell for braille display devices

The braille system is one of the most recognizable language systems for those with visual disabilities. With the advance of technology, the use of braille system is not only limited to physical books with raised dots, but it is also has been implemented in mechanical devices. This allows digital inf...
