Sounds good: new 3D imaging technique may lead to improved hearing aids
A new 3D imaging process developed by MechE Professor Douglas Hart holds the potential to make hearing aids both easier to produce and more effective. The process, which involves inserting a tiny, liquid filled balloon containing a camera into the patient's ear, makes it possible to record detailed information about the shape of the ear canal in real time. The inspiration for the new technique came out of left field, while Professor Hart was studying the thickness of engine oils using a process called emission reabsorption laser induced fluorescence (ERLIF). For more in-depth coverage of Professor Hart's work, you can read about it in both Fast Company and Technology Review.
