aking an important step forward for self-powered systems, researchers have built a nanogenerator with an ultrahigh output voltage of 209 V, which is 3.6 times higher than the previous record of 58 V. The nanogenerator, which has an area of less than 1 cm2, can instantly power a commercial LED and could have a wide variety of applications, such as providing a way to power objects in the “Internet of Things.”
