Australians designing medical microrobot that can float on human arteries.The unit length of 0.25 millimeters create James Friend and his colleagues from the laboratory of micro- and nanoscale physics Monash University.
Freund claims that his microbots is actually the world's first robot capable of traveling in the circulatory system.Here it will be equipped with a camera, the communication system and can carry a different payload (e.g., the adhesive for the walls of vessels).
This is not the first work in this area; however, there are differences between the Australian project.Thus, previously built trehmillimetrovy prototype Chinese medical robot designed for cleaning of arteries, but it is moved by applying a magnetic field from the outside.
Australian same machine will have its own engine, based on a piezoelectric crystal, vibrating at an ultrasonic frequency, and screw, which converts these variations in rotation group of flagella.
Swiss microbots also acted only by external fields.But actually
At the end of this year, the Australians are going to show a working prototype: cylinder of a length of about a centimeter and a thickness of less than a millimeter, according Membrana.And in 2009, the final version should appear microbots.
It can be injected into an artery using a syringe.The device will float in the body, obeying commands from the outside, and after the job back to the starting point, where it will draw again syringe.
