Sound waves are incredibly important - we use them every day in applications like communications, medicine, and sensing. Vannevar Bush Fellow Dr. Jennifer Lewis and her team at Harvard University have potentially extended the utility of sound waves to additive manufacturing. In a new paper published in Science Advances, the team created a tool that uses sound waves to carefully control the size and placement of droplets, even for highly viscous liquids. This research could have an important impact on industries such as food, cosmetics, and especially biopharmaceuticals. Click here to read more and watch a demonstration video.
