Researchers are working on the chilling of food and other resources using sound waves. The compression and expansion of waves produce heating and cooling respectively. It is far more efficient than the usual gas a refrigerator uses. The gas inside gets pressurized which produces sound waves; it make heat which is later absorbed and so chills the content of the fridge.
- Ultrasonic welding
Sound waves are the new way welding could take place in the future. These waves can easily travel to the sides and corners of the adjacent metal pieces and effortlessly join them without any difficulty. It is much cheaper as compared to the old ways of welding and does better work.
- Stealing Credit Card Information
Scientists discovered a new way of transmitting data using sound waves. One of them found a virus residing in the BIOS of the system and later doubted that it broadcast due to sound from a speaker. Experiments started, and the transmission of a virus via sound waves proved to have some basis, but this leads to increase in unauthorized access to the system.
- Acoustic Scalpels
Doctors use the sound wave to perform various operations. It includes ultrasound and breaking of the kidney stones, but with the current progress in technology, they are using it for various other functions. It is so accurate that it can be used to detach a single cell from a large number of cells; it is the future and is easily used to perform various single cell operations.
- Charging our smartphones
Scientists are finding new ways to generate electricity to charge up your smartphones. Nokia already patented the idea of generating electricity from movements. Since sound compresses and expands, so this leads to the generation of electricity and can be used to charge our smartphones without any wires.
- Turning human body into microphone
Researcher’s at the famous studio of Disney’s developed a device that makes the human body a functioning microphone. It allows us to transmit the message to the other person by just touching them on the ear without even uttering a word. The message is first recorded and stored in the computer and get converted to a file. The folder is transmitted to the microphone using a wire. It creates a vibration and transfers without any hindrance.
After learning that data can be transferred using sound waves, this also makes the data prone to various viruses and undercover work. It is easy for thief and conman to steal the data from such sources and transmission.
- Acoustic Cloaking
What if I say you can hide objects using only sound waves, weird? But with this idea one is even capable of doing that, a device that conceal objects takes the shape of the pyramid that is full of hopes so, if anyone places an object beneath that pyramid, the object can’t be seen if one observes from any angle.
- Tractor beams
Yes, you hear it right a scientist is trying to make real life tractor beams, which allows objects to displace without any physical contact with the object. It will be beneficial in various fields.
- Haptic Holograms
Scientists are trying to make the Star Trek tech in real life. It allows you to move devices by using gestures or by exerting the force on your skin. Say, if you are cooking but your hands are dirty, and you need to turn the page of the cookbook, so with this, you just need to make a gesture of moving a page that the work is complete. It eases the life and changes the way we do many things.
