Give Them Data They've Never Had Before
After a workout, do you really know what you've accomplished? Students at Northeastern University developed a sensor-equipped athletic shirt that records data about your exercise habits.
Called Squid because its sensors look like tentacles, the shirt wirelessly transmits information from your muscles to an Android app and website, which users can log into to track their own progress. The sensors capture data like heart rate and number of reps, and can provide instant feedback by vibrating when an exercise is done wrong.
