Scientists have invented a press method sound waves


Scientists claim that their way is much more perspective, than existing the inkjet and electrodynamic printing. Researchers of Harvard University have developed a new method of the press which uses sound waves for creation of drops of liquids. It is said on the website of the university. It is noted that similar methods are used, for example, in microbiology. The existing methods of the inkjet or electrodynamic printing can use only liquid in the narrow range of viscosity. Authors used the acoustic resonator in which the printer head nozzle is located. The resonator creates a standing sound wave which affects a drop of ink. Changing parameters of a sound wave it is possible to regulate the drop size. This method allows to use for the drop press of liquid with very high level of viscosity, up to liquid metal. Scientists expect that the developed method will find application in the biological, cosmetic and food industry. Earlier, watching pandas in the zoo San Diego and studying their behavior, scientists have found out that these animals are capable to perceive ultrasonic range. Also it was reported that geophysics by means of a ground seismograph have recorded the acoustic anomalies caused by free fluctuations of an ocean bottom.
