The Smallest Submarine in the World

With a diameter of 650 µm it finds place in the narrowest chanels. It's
driven by a rotary magnet and allows a voyage of discovering even in the
smallest space.

This submarine, manufactured by microTEC, Duisburg, puts the vision of the
microsystem technology in practice and offers for instance absolutely new
vistas for medical diagnostics. Featured with sensors it could realize
completely new methods for examinations, that are extremely gentle  for the
patients.

For the manufacturing of the micro submarine the new features of RMPD
(Rapid Micro Product Development) are used to integrate different materials
seamlessly. Mini magnets, that are fitted in the screw, build the
foundation for the driving system oft the submarine.

You see this smallest submarine in the world at the Hannover Industrie
1998,
H18, 1. OG, M06 from 20.-25. April.
