Congratulations on your accomplishments. This sounds like something that might be of interest to Brown’s Nelson Center of Entrepreneurship and/or The school of Public Health. I would consider reaching out to either program and incorporating in detail your thought process for developing this device and how Browns resources and the OC could support this effort in your essays.
Look up the Brown venture prize and prior winners as a template of why you and Brown may be a good fit for one another.
Good luck and please DM if you want more specific advice about this approach.
