Flextrapower (formerly known as Bonbouton) is a healthcare startup from New York City that monitors the temperature and humidity of diabetic patients' feet to help prevent severe complications such as foot amputation. Often in the US, people have to wait several days after making an appointment to see a doctor. Therefore, by the time they see a doctor, sometimes the condition is deteriorated too much, resulting in leg amputation. The company created nano-level ultra-thin sensors that fit inside the shoes' insoles, monitored via a smartphone app. AI can read signs that could lead to severe conditions and report them to the patient and their doctor.
