Last night, a team of 15 student inventors from Concord High School presented their Mid-Grant Technical Review to visitors from MIT, which earlier this year awarded them $10,000 through the Lemelson-InvenTeam Grant process. In addition to two distinguished guests from MIT, the audience included Governor Jack Markell, parents, teachers, the team's volunteer mentors, representatives from Christiana Care, representatives from the Delaware STEM Council, business leaders, and School Board members. The review allowed the team to share the scope of work and progress to date for each component of their invention, which is a metal detection system for hospital and health care textiles. Their invention offers a potential promise to address similar concerns not only for Christiana Care textile workers but health care providers across the nation. Audience members had the opportunity to view a functioning prototype of the invention, review the circuitry and coding being used, and provide feedback. The information will be used to revise and refine subsequent prototypes until the Concord team submits its final project to MIT in June.
