Recently, the final of the 10th “3S Cup” Internet of Things Technology and Applications "Three Innovations" Competition for College Students was successfully held in Wuxi, Jiangsu. The competition is hosted by the China Institute of Communications and brings together over 640 teams from 129 universities across the country, including Tsinghua University, Zhejiang University, Harbin Institute of Technology, Xi'an Jiaotong University, and Southeast University. The panel of judges rigorously evaluated the participating projects based on creative novelty, design uniqueness, technological leadership, technological maturity, and market prospects. Ultimately, 20 first-place awards, 40 second-place awards, and 59 third-place awards were selected. Among them, ZJUI’s "COPULA Team" composed of Liang Xuanhong, a 2022 master's student in Electronics and Information, Ma Kun, a 2022 master's student in Artificial Intelligence, Sun Chuhan, a 2023 master's student in Artificial Intelligence, Li Jiaxing, a 2022 master's student in Computer Science, and Zhu Jiaqi, a 2023 master's student in Electronics and Information, won the national first prize in the competition. The team's instructor, Assistant Professor Yang Hao (Howard) of ZJUI, won the "Excellent Guidance Award".

The award-winning project "WiFi based Human Respiratory Sensing System" focuses on remote monitoring scenarios for home-based elderly care, using the latest large-scale commercial WiFi 6E network card to achieve real-time, accurate, and non-contact human respiratory sensing without the need for additional hardware deployment. After discovering the unique phenomenon of "four phase ambiguity" on WiFi 6E network cards, the research team revealed the causes and manifestations of this phenomenon through a series of benchmark experiments, proposed a phase correction algorithm for "four phase ambiguity", and achieved good results in scenarios such as human respiratory sensing required for remote monitoring of home-based elderly care. It provides an effective solution for further promoting the integrated application of new generation information technology, mobile terminals, wearable devices and other intelligent devices in elderly care scenarios such as home, community, and institutions. Part of the research results of this project have been accepted by the international conference IEEE Ucom 2024 and the flagship conference in the field of communication IEEE Globecom 2024.

When it comes to award winning, Liang Xuanhong shared with us, "This experience has deeply impressed us on the important role of technological innovation in promoting the Internet of Things (IoT) industry, especially in the new generation of information technology represented by the Internet of Things. Through this competition, we have envisioned a new smart service system for infrastructure in the future intelligent era and proposed a wireless sensing solution for smart elderly care scenarios. This not only enhances our team collaboration and practical innovation capabilities, but also deepens our understanding of collaborative innovation between communication technology and industrial applications and lays a solid foundation for our further exploration and innovation in the communication and IoT industries.” The research work on wireless breath detection originated from the Human Space X project organized by Professor Ouyang Hongwei. The team members conducted nearly a year of exploration on the characteristics of Wi-Fi 6E network cards, and subsequently developed a new high-efficiency and high-precision detection algorithm, sharing youth wisdom and solutions for the current integrated communication and perception technology in the wireless field.” The team’s instructor, ZJUI Assist Professor Yang Hao shared with us.
In order to guide university students across the country to actively carry out collaborative innovation between communication technology and industrial applications in the new quality productive forces of the Internet of Things, this competition requires students to discover, raise and solve problems in the field of IoT technology and applications, accelerate the transfer and transformation of scientific and technological achievements, optimize the innovation ecological environment of university students, and build a public and open innovation platform. The competition focuses on the application of IoT technology in the new infrastructure "Smart Service System (3S)" solution, enhancing university students' awareness innovation, technological innovation, and industrial innovation (three innovation) capabilities in the field of IoT, injecting strong momentum into promoting the sustainable development of the IoT industry.
In this competition, ZJUI's participating faculty and students demonstrated solid interdisciplinary professional skills, good teamwork spirit, and innovative thinking. They proposed practical and effective solutions to multiple difficulties and pain points in IoT technology and applications, contributing their youthful strength to promoting the empowerment of high-quality development and innovation upgrading by intelligent IoT.
