In light of these path-breaking developments, it is only appropriate that we are hosting this edition of the World Micromachine
Summit, which will once again turn the global spotlight on Ras Al Khaimah and reaffirm our ongoing commitment to a sustainable future," said Sheikh Saud.
Slow and weak, the rotors circle at about twice the speed of the second hand on a watch and generate only a ten-thousandth as much torque as typical electrically powered micromachines
But he says his initial NASA brief to design a muscle-powered micromachine
to repair spacecraft punctures is still several decades away.
Designers draw a picture of the micromachine
part on a light mask (like a transparency), which acts like a photographic negative.
The development of tiny "micromachines
" in Japan has brought the fantasy of Isaac Asimov's Fantastic Voyage one step closer to reality.
The research suggests a way for engineers to power and control micromachines
implanted in the human body or other fluid-filled environments.
The work was reported in the March issue of the Journal of Micromachines
However, transferring fully developed muscles from an organism to a micromachine
is impractical, notes Xi.
Laser microfabrication uses industrial lasers to micromachine
and micro-weld small components.
The new micromachine
, a variable-reluctance motor suspended by gimbal springs, moves a data recording read-write head through a range of [+ or -]10 microns just above the surface of a spinning data storage disk and positions it to submicron accuracy.
Such a fully developed micromachine
is at least five to 10 years away, according to Paul McWhorter, manager of the silicon technologies department at Sandia.
A MAGNETICALLY DRIVEN MICROMACHINE
has been developed for use where popular electrostatically driven actuators fall short.
