As the demand for energy grows worldwide, manufacturers of electronic equipment are continually looking for ways to improve the energy efficiency of their designs. One of the primary goals of the Internet of Things (IoT) is to help consumers become better users of energy—on the factory floor, at home, at work, on the road, while exercising, or at the doctor’s office. In this Basics Of Design, we will discuss energy efficiency and the IoT, and spotlight technologies and devices that are helping engineers design products that use less power while still boosting performance.
