Article in Design News – Dramatic reductions in voltage and power requirements are making tiny piezo motors and drive systems an interesting option for portable, low-power medical devices. By eliminating the need for the high voltage normally associated with piezo systems, a new piezo motor design from New Scale Technologies enables miniature motion systems that operate on a single 3-V battery without using voltage boost circuits.
