How ambient energy could power the internet of things

(American Chemical Society) In the modern world, we are increasingly surrounded by digital sensors, cameras and communications devices sending data cloud-based analysis services. Those devices need power, and designers are finding new ways to draw it from ambient sources rather than rely on batteries or hard-wired grid connections. This week Chemical & Engineering News, the news magazine of the American Chemical Society, examines energy harvesters and their role in the growing internet of things.
