发明名称 ACTUATION MECHANISM FOR BRAILLE DISPLAYS
摘要 According to the present invention, there is provided an improved refreshable tactile display apparatus including a housing, bias compression springs, sliding blocks, pins, and a shape memory alloy wire. The sliding block is actuated by the interaction between the bias compression spring and the shape memory alloy wire. The shape memory alloy wire is then activated by current driven from a power supply in either a modulated or unmodulated fashion.
