My team and I won second place at MakeMIT 2016 for Align.

As students, we sit a lot, and it leads to bad posture. Eventually, it becomes chronic back pain, so we wanted to create something to help us fix our posture. Align is a set of sensors that detect the curvature of the spine. When the user reverts to a bad posture, Align activates provides haptic feedback at the problem area as a reminder to straighten up.
