As humans become more and more obsessed with their health, it fuels the health and fitness industry. One of the most popular current trends is being able to track your fitness through sensors. A common product which helps do this is the Fitbit.

You can count the steps you have taken, the distance you have covered, the rate of your heart and just how many hours of sleep you have had at night. All you have to do is ensure that you are wearing the fitness tracker all through the day and night, and of course that you charge it regularly.

Now researchers at Harvard University have come up with a highly sensitive soft capacitive sensor made out of silicon and paired it with a stretchy fabric that moves and flexes along with the muscles of the body. The combination has allowed them to come up with a fabric which can literally turn into a fitness tracker.

Professor Conor Walsh said that they were excited about this sensor as by leveraging textiles in its construction it is inherently suitable for integration with fabric to make smart robotic apparel. So will the end product of this science experiment be a pair of pajamas that double up as a Fitbit?
