A 'fantastic voyage' through the body -- with precision control
Date:12/15/2011

ination of copper coils and flexible polymer. The magnetic field creates a vibration in the tail which allows for movement, and electronics and microsensors embedded in the capsule allow the capsule's operator to manipulate the magnetic field that guides the movement of the device. The use of copper, a non-ferro magnetic material, circumvents other diagnostic challenges posed by MRI, Dr. Kosa adds. While most magnets interfere with MRI by obscuring the picture, copper appears as only a minor blot on otherwise clear film.

The ability to drive the capsule, Dr. Kosa says, will not only lead to better diagnosis capabilities, but patients will experience a less invasive procedure in a fraction of the time.

Microrobotics of the future

In the lab at the Brigham and Women's Hospital, Dr. Kosa and his fellow researchers have tested the driving mechanism of the capsule in an aquarium inside the MRI. The results have shown that the capsule can successfully be manipulated using a magnetic field. Moving forward, the researchers are hoping to further develop the capsule's endoscopic and signalling functions.

According to Dr. Kosa, a new faculty recruit to TAU, this project is part of a bright future for the field of microrobotics. At the university, his new research lab, called RBM2S, focuses on microsystems and robotics for biomedical applications, and an educational robotics lab, ERL, will teach future robotics experts studying at TAU's School of Mechanical Engineering.
