Handling of micro-objects and measurements are the major operations, which can be executed by the fine-positioning module.
The proposed design in principle can levitate conductive micro-objects and accelerate or move them over a predefined trajectory.
We are developing a process to assemble and orient micro-objects, and then transfer them to a final substrate to be used for electronics, sensors, metamaterials and other applications.
This paper overviews this development, including the discussion of (1) the framework and a prototype of the automated bio-micromanipulation system, (2) the design and control of the micromanipulators, (3) the micro-visual-servo architecture, modeling of image Jacobian and recognition algorithms of micro-objects, and (4) the experiment to validate various concepts proposed.
Microgripper is actuated with lateral comb drive system and transverse comb system is used to sense contact between micro-object and microgripper jaws.
This paper describes the development of a microgripper mechanism capable of delivering high precision and fidelity manipulation of micro objects.
This paper analyzes human operation of an arbitrary single micro object under 1mm while observing the object and systematically studies the design of a micro handling system to perform such operations.
Fatikow proposes an automatic control frame for the micro-object manipulation and positioning based on vision feedback, which greatly improves the working efficiency [33].
The captured image was analyzed by the Hough transform algorithm, providing the microrobot's locations and sizes, and the micro-object's locations and sizes.
The integrated strategy combines strengths of optothermal (e.g., precise size control in bubble creation and easy delivery of micro-objects into target position) and acoustical (e.g., on-demand capturing and precise sorting of micro-objects) strategies.
6 Among the various applications proposed for medical micro-devices, targeted drug delivery and micro-object transportation can be implemented using biocompatible and magnetically actuated agents.
