Concordia University have created a device which turns liquid into plastic using sound waves.The method, called Direct Sound Printing (DSP), makes it possible to create shapes underneath the skin that would previously require intensive surgery, such as cochlear implants for the hearing impaired or a new nose.
Patients just need to be injected with a small amount of plastic resin. Then, researchers zap the skin with ultra high-frequency sound waves in the blink of an eye.This triggers a chemical reaction which turns the resin into a solid by forming an air bubble.In this way, the new method makes it possible to 'print' objects inside the human body.
Researchers tested the technology on 1.3 inches of pig. The sound energy can be unbelievably hot, reaching temperatures of up to 27,000 degrees Fahrenheit.
Luckily this is for such a short amount of time that nobody gets hurt."DSP introduces the possibility of noninvasive deep inside the boy printing," researchers said in the study.
