This electrostatically driven comb-drive actuator had 19 fingers of rotor with 30 microns width of each finger. It was fabricated by synchrotron x-ray lithography technique at micromachining lab, the Synchrotron Light Research Institute, Thailand by Winai Wanburee, a graduate student from the Suranaree University of Technology (Doctor of Philosophy, Electrical Engineering Program). The patterns was 300 micron-high. The fingers of stator was grounded and the fingers of rotor were biased with several level of DC voltage 1 Hz pulses.

Each actuator covers a 19mm hexagonal area and can move the fiber in that area without interferring with neighboring actuators using R-Theta axis arrangement controlled by miniature stepper gearmotors. Only radial axis shown with top removed for clarity.
