The objective of this project is to design a cell orientation control system using a rotating electric field. In particular, the system utilizes two electrostatic phenomena known as electrophoresis and electro-rotation. The device used for creating the electric field was designed and fabricated using the MEMS fabrication technique. The cell orientation control system also includes a vision tracking system that senses the orientation of the cell and a PID controller. Overall, the system is able to control the orientation of the cell with zero steady state error. The objective of this project has been met.
