抜粋

Electrorheological (ER) suspensions, which behaves like a Bingham fluid having yield stress, is believed to be capable of applying to various mechanical systems since it can be rapidly change in reversible manner by applying electric field. In this research, a Braille display system driven by micro-diaphragm ER actuators which can be driven by relatively low supply pressure is developed. Since the diaphragm actuator uses a polyurethane film of 0.02 mm thickness and very low stiffness, it can be driven by about 240 kPa supply pressure. By using the actuator, experiments for displaying six tactile pins and step response of pin's height are performed.
