Vibrational Braille code display with MEMS-Based hydraulic diplacement amplification mechanism

We demonstrate an efficient vibrational Braille code display with large-displacement MEMS actuator arrays. The large displacement is realized by hydraulic displacement amplification mechanisms (HDAM). Static and dynamic characteristics of HDAM were investigated and 18- and 11-fold amplification were achieved in static and dynamic (at 70 Hz) actuation… CONTINUE READING
