PolluCell: Using Waster Materials and Pollution to Generate Electricity
Sahil Doshi
2014 Winner
Meet Sahil. Sahil entered the competition because he loves science and he wanted to get to know others who shared similar interests. His battery cell invention will use carbon dioxide and other waste materials to help clear the atmosphere from greenhouse gas emissions and, additionally, be a low-cost alternative for electricity in developing countries.
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.
Nano Particle Wound Care
Kara Fan
2019 Winner
Meet Kara. Kara formulated a nano particle liquid bandage to replace the use of antibiotics and help reduce the development of super bugs due to overuse of antibiotics.
Enhancing Wind Power
Maanasa Mendu
2016 Winner
Meet Maanasa. Maanasa hopes her invention helps make wind power a globally applicable energy source. She created a device utilizing piezoelectricity materials that are both eco-friendly and cost efficient.
Spark Care+: Personalized Music Therapy for Mental Health Disorders
Sarah Park
2021 Winner
Meet Sarah. Sarah developed Spark Care+, a personalized music therapy treatment for mental health disorders using artificial intelligence (AI), galvanic skin response (GSR), and photoplethysmography (PPG).
Salt Water Sandless Sandbag
Peyton Robertson
2013 Winner
Meet Peyton. America’s Top Young Scientist today, world renowned inventor tomorrow. Peyton’s invention of a more efficient sandbag to reduce salt water flood damage captured our judges’ attention. But it was his commanding delivery, innovative thinking, and sound grasp of the scientific method which captured him the title.

As America’s Top Young Scientist, it’s no wonder Peyton’s favorite subjects are science and math. He enjoys researching a problem or challenge and thinking through alternatives and creative solutions.
