The waves in question are known as “surface reflected bulk waves.” Surface reflected bulk waves are a combination of bulk sound waves and surface sound waves.
Bulk sound waves cause an object to vibrate as one, kind of like holding a carpet at one end and shaking it. In contrast, surface sound waves only cause the surface of the material to vibrate, like waves in an ocean. By combining the two, researchers have created a sound wave class that is far more powerful than either carpet shaking or crashing waves alone.
Previously, sound waves have not been gentle enough to manipulate stem cells. These new waves, though, won’t cause damage to the delicate cells.
Future Uses
Study co-author Dr. Amgad Rezk, from the Micro/Nano Research Laboratory at RMIT and his team created a device to utilize surface reflected bulk waves in medical devices. It’s called HYDRA (don’t worry- not like Marvel’s Hydra). It passes electricity through a chip, converting it into sound waves that can break the liquid into an inhale-able spray.
