Bimetallic strip makes chepaer Braille Disply

. Posted by Hello

Braille Display Utilizing bimetallics as the medium to create the Braille characters instead of piezoelectrics greatly reduces the cost of the Braille display. An electric current is sent through a 30 gage wire (spot welded to the bimetallic strip) which causes the bimetal to bend, raising a plastic rod 0.5mm, the height a Braille dot. When the current is turned off, the bimetal quickly cools and the rod will fall back into its hole, allowing a different character to be created.
