Abstract

See full text

System and method that allow to jointly cause movement of multiple micro-and-nano-objects to desired positions are described. A high speed camera tracks the locations of the objects. An array of photo-transistor-controlled electrodes is used to generate a dynamic potential energy landscape for manipulating objects with both DEP and EP forces, and a video projector is used actuate the array. One or more computing devices are used to: process images captured by the camera to estimate positions of the objects; generate desired trajectories of the objects using an objective function; compare the desired chiplet positions with current positions and generate input signals to minimize the error between them; and map the control inputs to images that are projected on the array using a video project. The projected images activate or deactivate electrodes, as indicated by the control inputs.
