“By tuning the sound waves, we can create any pattern we want on the surface of a microchip,”

In a breakthrough discovery, researchers at RMIT University in Melbourne, Australia, have harnessed the power of sound waves to enable precision micro- and nano-manufacturing.

The researchers have demonstrated how high-frequency sound waves can be used to precisely control the spread of thin film fluid along a specially-designed chip, in a paper published today in Proceedings of the Royal Society A.

With thin film technology the bedrock of microchip and microstructure manufacturing, the pioneering research offers a significant advance – potential applications range from thin film coatings for paint and wound care to 3D printing, micro-casting and micro-fluidics.

Professor James Friend, Director of the MicroNano Research Facility at RMIT, said the researchers had developed a portable system for precise, fast and unconventional micro- and nano-fabrication.

“By tuning the sound waves, we can create any pattern we want on the surface of a microchip,” Professor Friend said.
