APPLICATIONS AND ASPECTS OF SUPERCAPACITOR IN IOT DEVICES AS A SUSTAINABLE ENERGY SOURCE

Today, the Internet of Things (IoT) is an emerging field of recent technologies. Every field of engineering, technology, and real-time management has IoT applications such as transportation, agriculture, healthcare, manufacturing, wearable, smart grid and energy saving, smart home, smart management systems, etc. Also, AI has captured wide-area applications in the automobile industry, surveillance, security, education, entertainment, gaming, e-commerce, portable devices, robotics, biomedical instruments, etc. Electrical and electronic devices are used in IoT-based applications. They are required efficient energy to operate for a long time effectively. These types of devices required offline and online energy storage devices that charge on time or require less recharge. The supercapacitor has a high capacitor, rapid charging/discharging cyclic rate, cost-effective and eco-friendly. Our objectives are to study supercapacitors for providing energy and power supply backup to IoT devices. Electronic devices mainly operate on dc signals and electrical instruments work on signals. The supercapacitor plays an important role to supply energy which stores an extremely large amount of electrical charge. It is the future of batteries and replaces the old bulk batteries with tiny high-performance flexible sustainable supercapacitors.
