Microscopic Visual Feedback

Concept

With the rapid development of micro technology, it becomes more important to handle micro objects such as Micro-Electro-Mechanical Systems (MEMS) and cells. For human beings, however, handling micro objects through microscope is very difficult. To solve this problem and realize automatization of manipulation of micro objects, we proposed MVF (Micro Visual Feedback). MVF is a technique that uses High-Speed Vision as a sensor to control micro objects. It has three advantages: high precision, high-speed, and no physical contact. By using MVF, systems can automatically control micro objects.
