Abstract
A feedback control system, comprising a flexible rod that may have an anchored end and a free end, the rod free end movable upon the application of electric potential to the rod, a current source coupled to the rod, a movement sensor disposed on the rod, and a circuit electrically coupled to the movement sensor and to the current source and having an external input, wherein the rod may include a shape memory alloy, a bimetal, or a piezoelectric material and wherein the rod may include one or more strips arranged in a pattern such as lengthwise or helically.
