Finsen Headphones: Treating Mid-Ear Infections Using Machine Learning and Phototherapy
Leanne Fan
2022 Winner
Every year, there are 700 million cases of mid-ear infections (Otitis Media) and nearly 21,000 deaths worldwide. Many of those impacted are children and underprivileged populations. Without medical access and or healthcare, diagnosis and treatment of mid-ear infections are often difficult. Leanne’s invention, Finsen Headphones, provides a low-cost option to detect and treat a mid-ear infection using machine learning and blue light therapy – potentially preventing up to 60% of hearing loss in children.
The Ocean Energy Probe
Hannah Herbst
2015 Winner
Meet Hannah. Hannah's Ocean Energy Probe aims to provide a stable power source and fresh water to developing countries around the globe by using untapped energy from ocean currents. The energy is stored in a generator, and then can be harnessed for many uses, including the desalinization of water.
