Abstract:
With the development of the Internet of Things (IoT), a large number of wireless devices have been deployed in our surrounding environment, and the power supply problem of these IoT devices has become increasingly prominent. The installation and maintenance of a large number of widely distributed sensors are very cumbersome. In this presentation, we will introduce a self-powered floor tile design based on electromagnetic energy harvesting (EMEH) technology. Although many floor tile designs using various improvement methods have been proposed before, as an energy harvesting floor designed based on first-principles, this solution integrates energy enhancement and information transmission, with the most compact structure and strong inclusiveness for ultra-low-frequency motion. Compared with other EMEH energy harvesting floor tile designs, this solution also has the advantages of a stroke distance of less than 3 mm and a small floor tile thickness, which has almost no impact on natural walking. With its unique displacement amplification and mechanical energy buffering and release mechanism, this solution solves the problems of large activation displacement, large volume and low energy conversion efficiency. Such a smart pavement is expected to further provide practical pedestrian-related information or human-computer interaction activities, such as crowding degree monitoring, individual tracking, and advertising interaction.
