Heart & Sole: A device for diabetics to measure blood flow and oxygen levels in their feet to gauge the progression of neuropathy

Katia Avila and her classmates, of the 2017 and 2018 Garey High School Lemelson-MIT InvenTeam, invented a wearable device called Heart & Sole. The device uses sensors to gauge the progression of neuropathy and key disease indicators by measuring blood flow and oxygen content in a foot for diabetics. Katia, who had little knowledge of engineering prior to this experience, led the production of the oxygen saturation sensor for the InvenTeam project. She credits her experience with inventing as a turning point in her career path.

The team filed a nonprovisional application for patent in 2018 with pro bono support from the Microsoft #MakeWhatsNext Patent Program. They were awarded U.S. Patent 11,382,564 on July 12, 2022.
