Every physical movement we undertake expels some energy, so wouldn’t it be awesome if we could capture all of that ambient force and turn it into power with some practical value? The scientists at the University of Southampton may have figured out a way to do just that. Steve Beeby and his brilliant team at the university’s School of Electronics and Computer Science are developing an energy harvesting film that can be screened directly onto any piece of clothing. This innovative film will use a combination of printing processes and active-printed inks to create garments able to capture up to 67 watts with each step! Barely detectable, this little innovation could soon be clearing the path for low-cost and flexible energy harvesting textiles.
