Ultrasonic waves are sound waves that have a very high frequency. They are so high that we cannot hear them with our ears. These waves are often used in technology to do things like cleaning objects, detecting objects underwater, or even imaging inside our bodies during medical procedures.

The Mi 5s also features a 4 - megapixel selfie camera and a 3,200 mAh battery; on the front, you'll find a seamlessly integrated fingerprint sensor, which can recognize a 3D map of your fingerprint
through ultrasonic waves and therefore negates the need for a separate button on the fascia.
The Los Angeles - based company has developed technology that
transmits ultrasonic waves (at a register well beyond what's audible) that are translated by devices as a microscopic quiver; this vibration is converted back into an electrical charge to power anything with a battery, no wires or wall plugs required.
«The vision is to implant these neural dust motes anywhere in the body, and have a patch over the implanted site
send ultrasonic waves to wake up and receive necessary information from the motes for the desired therapy you want,» said Dongjin Seo, a graduate student in electrical engineering and computer sciences.
Some of the laser energy is absorbed by the tissues and converted into heat, leading to rapid thermal expansion inside the tissues that
produces ultrasonic waves.
High -
intensity ultrasonic waves instigate the physical movement of extracellular fluid, leading to direct membrane cavitation or air - bubble collapse and subsequent pore induction (15).
As small as an ordinary alarm clock, this nifty gadget sends out high -
pitched ultrasonic waves to put a stop to dogs» incessant barking without you hearing it.
Radiographs (X-rays) and / or ultrasound (visualizing deep body structures by
recording ultrasonic waves) may be needed for a definitive diagnosis.
An ultrasonic fingerprint scanner works by
deploying ultrasonic waves to recognize a person's fingerprint, irrespective of whether the finger is wet, sweaty or covered in filth and grime.
are similar to ultrasonic humidifiers, but instead of
using ultrasonic waves, they break up water drops using a rotating disc.
«We've discovered that we can detect differences in the crystallisation of cocoa butter
with ultrasonic waves,» adds Professor Koen Van Den Abeele from the KU Leuven Department of Physics and Astronomy.
The Xiaomi Mi 5s sports a button - free front design, thanks to the all - new under - glass ultrasonic fingerprint sensor that recognises a 3D map of each fingerprint
through ultrasonic waves.
Available Intelligent Parking Assist (IPA) uses
ultrasonic wave sensors to size up a parallel parking space and then, when activated by the driver, can steer the car into it.
Vivo uses the ultrasonic technology in its sensor that
emits ultrasonic waves that capture a precise image of a user's fingerprint to unlock the device.
It was an inspiration for young aspiring architects everywhere, as we described in an earlier post «a glimpse of carefree futuristic living inside a plastic - walled floating cruciform structure with picture phones, height - adjustable sinks, dishes washed
by ultrasonic waves, and atomic food preservation.»
Ultrahaptics pairs gesture technology with tactile feedback by using
ultrasonic waves that cause the user's skin to vibrate, creating the illusion of touching buttons or other physical objects and allowing users to control devices seemingly in mid-air.
One of the best thing about this humidifier is the fact that it uses
ultrasonic waves to generate a fine mist of moisture - laden air.
By incrementally varying the frequencies of
the ultrasonic waves, the duo can pinpoint the frequency at which a target resonates — like the amplification of a particular hum in a shower stall.
«When the cocoa butter is liquid,
the ultrasonic wave is reflected in its entirety.
When blasted with
ultrasonic waves, liquids can undergo a process called acoustic cavitation, in which bubbles form and violently implode.
To find out, Mercader took them back to his lab in Calgary and cleaned the dirt off the rocks by submerging them in water and beaming them with
ultrasonic waves.
A system that used
ultrasonic waves to transmit would be far less cumbersome.
A system that transmitted using
ultrasonic waves would be far less cumbersome.
The researchers found they could tune the dimensions of the scrolls by varying the treatment duration and the frequency of
the ultrasonic waves.
Additional changes include a new front park assist system that detects objects up to four feet away thanks to
ultrasonic waves.
Ultrasound is a machine that uses
ultrasonic waves to help Pacific Pet Hospital visualize the internal organs of a pet.
The company also confirmed that
these ultrasonic waves are absolutely safe for humans.
But the future iPhone may come with a much powerful tech that would allow the device to be charged from longer distances using
ultrasonic waves.
However, it is worth mentioning that the efficacy of
ultrasonic waves to deter mosquitoes has been contested, to the point that a review of 10 field studies concluded that they «have no effect on preventing mosquito bites», very much contrary to LG's claims.
Dubbed Qualcomm Snapdragon Sense ID 3D Fingerprint Technology, the tech uses
ultrasonic waves to penetrate through the outer layers of your finger to build a three - dimensional map of your fingerprint that's much harder to duplicate than a mere capacitive scanner as you'd find on the Samsung Galaxy S6 or iPhone 6.
As this technology uses
ultrasonic waves, it is superior to capacitive and optical scanners found on current smartphones as it can function even with wet fingers.
