Abstract

A novel polymer-based bistable out-of-plane (OoP)-drive with electrothermal actuation for portable Braille area displays is presented. The drive consists of an OoP-actuator which moves a tactile Braille-pin out of the display surface and an in-plane (IP)-actuator which locks the pin position. The system is fabricated using UV-lithography of the epoxy based dry film photo resist SUEX. It has a small footprint of 10.7 x 2.5 mm² and is suited for a 2.5 mm Braille grid. A high OoP-deflection up to 580 μm at 125 mW power consumption is achieved.
