Self-charging smartwatches and health trackers could be a step closer following the development of tiny mechanical devices powered by movement, a study suggests.The new mechanisms – which are twice as powerful as similar existing devices – could offer an energy-efficient and sustainable alternative to batteries used in wearable technologies, researchers say.Edinburgh engineers have developed a technique to create versatile materials that generate electricity by harnessing energy produced by movement of the human body.
