Engineers have made a device that can move and manipulate objects by using ultrasound alone. They say that this technology enables them to eventually develop a device that uses ultrasonic waves to unload screws to assemble sophisticated electronic devices.
"mystical doctor" fans dream to have their own ultrasonic screwdriver
a research team from University of Bristol. An experiment was carried out in the field of ultrasonic pressure. The device could be shaped like a screwdriver head, much like the little thing used in "doctor of mysteries" above. The news of
will undoubtedly inspire the young fans of the film "doctor of secrets". After seeing that their heroes used this tool to escape danger many times, they dreamed of owning their own ultrasonic screwdrivers.
, however, although a doctor's weapon can perform many tasks, such as cutting, burning, welding, sending signals, controlling time machines, changing mobile phones and treating wounds, researchers remind that the ultrasonic screwdriver in their real life will only have some limited functions.
Bruce Drinkwater, an ultrasound engineer from the University of Bristol in the UK, said: "we have invented a device that allows us to use the power of ultrasound to move small objects like biological cells, and to classify and combine them."
"we are using very little force to do this because we do not want to damage the objects we move. However, this technology is quite real, and it is not without such a possibility to create something similar to the "mystery doctor" screwdriver.
"if we can increase the power of ultrasonic wave and create the power of cyclotron, then it is possible to unscrew the screws. In essence, what we are doing is using ultrasound to rotate the surrounding air and produce a miniature cyclone.
professor Shire J Wouter and his colleagues have created the prototype of the device, which can use ultrasonic waves to move special sized cells. By giving it an electric current, the tiny crystal vibrates and produces an ultrasonic shock wave in the surrounding air, which forms a pressure that can be used to push the cells. The size of the shock wave can be adjusted to move cells of different sizes, so that the sick cells can be removed from healthy cells.
their devices can also be used to separate dangerous substances. For example, anthrax can be separated from other powders by the same technology.
the professor claims that by increasing the size of the shock wave, a kind of gyratory movement can be produced, which can produce a "force field" of ultrasound and the ability to unscrew the screw. Other researchers have been using ultrasound to do gyro motion, so it can be used to equip sophisticated electronic components.
professor Shire J Wouter is currently engaged in the research of the big bang. He aims to motivate young people to devote themselves to science and technology. "We can do a lot of things to increase the force," he said. "We need to make the air move at a very fast speed to provide enough power to turn the screws. However, we have to inject dense gas into the surrounding space of the head to cope with more friction."
"the ultrasonic screwdriver is expected to be completed in the near future, but ultrasound technology has been applied to the medical and manufacturing industries and has achieved some exciting results."
ultrasonic screwdriver is one of the latest science and technology. These technologies, which were once imagined by science fiction writers, have become reality after that.
