and those smart devices driven by batteries are very limited by the amount of electricity. Designed a micro-energy harvesting and management system by analyzing environmental energy harvesting technology. Based on this system
tried to design a lowpower self-powered solution for a series of IoT devices in smart city vertical industries
and improved the existing system from many aspects
including the use of 5 G communications technology with higher energy efficiency. Enrich the application scenarios of smart cities and 5 G communication technologies
lay the foundation for the sustainable development of smart cities.
