Piezoelectric Dot Matrix Printer
I'd like to share a piezoelectric actuator used in a dot matrix printer. These printers were somewhat of a cross between typewriters and modern printers. An actuator would press a series of small dots onto a film which then imparts the ink onto the paper to display any shape. This particular picture is of an actuator the genesis of the Piezo.com team developed back in the early 1980s.
