DESIGNED SMALLEST MIKROTSEP THAT capable of driving devices at a considerable distance from the micromotor.
Mikrotsep that its structure is similar to a bicycle chain, except for the fact that each of its member could easily fit on a human hair, was made at the Department of Energy Sandia National Laboratories (Sandia National Laboratories).
The interval between the centers of the chain links - 50 microns (for comparison, the diameter of a human hair - about 70 microns).
As separate set mikrotsep axles can rotate the engine (depending on the size shestirenok star-mounted on axle, the device does not require the deployment of a plurality of tiny MEMS motors in the area from each other.
?If it were necessary, all the thrusters would occupy much space on chips |, says Sandia technician Ed Vernon, received a patent for this technology silicone mikrotsepi.
Mikrotsep makes it possible to drive the device located at a considerable distance from the micro-motor, saving considerable space on the chip.
Mikrotsep author says development may be used in the microchamber, which can find application in medical and security services.
Silicon mikrotsep with 50 units designed to convey the driving force from the rotating axis of the micro-motor, like a scheme used on the machines weaving mills. Chain system does not require any oscillatory motion back and forth, which exist in the flywheel and the transmission lever rotation and allow continuous or intermittent rotation of the motor axis.
Vernon produced mikrotsep, not mikroremen because, despite the fact that the silicone straps are tough and flexible, they produce too much of the transmission of rotational speed and the speed of the motor speed can not be adjusted. In this case, each link mikrotsepi able to strictly follow the cycle of rotation, repeated after 52 level, without creating any pressure on the motor shaft and the displacement of its center of gravity.
The longest distance communication connecting rod and the transfer of motor functions of the axis of the micromotor, which is supported by reducers, is not more than 500 microns. Mikrotsepnoe unit will develop the capability to design longer periods.
