【instrumentOnline R&D News】The School of Microelectronics at the University of Science and Technology of China has proposed a surface based on valley topological metasurfacessensorNetwork, the first application of topological physics in the field of biomedical sciences. The related research, titled "Body sensor networks based on flexible topological clothing," was published online on January 5th in Nature Electronics.
This study designed and prepared a valley topology metamaterial surface based on flexible conductive fabric, integrated it into daily clothing, and constructed a wearable and reconfigurable surface sensor network. This network utilizes topological boundary states to achieve efficient and low loss wireless signal transmission, significantly improving the communication quality and physiological signal monitoring capability of wearable biosensors in motion.
The research team has achieved flexible configuration of multiple independent wireless channels by designing two-dimensional modules with different topological phases. Experiments have shown that this topology clothing can achieve signal transmission enhancement of over 30 dB on the surface of the human body, and maintain stable performance under complex conditions such as bending, stretching, and human body fitting. Compared with traditional radiative communication networks, this system has significant advantages in energy efficiency, anti-interference, and data security.
In the physiological monitoring experiment, the research team integrated the topology clothing with multiple accelerometers and Bluetooth modules, combined with adaptive filtering and artificial intelligence algorithms, and successfully achieved high-precision monitoring of key physiological parameters such as heart rate and respiratory rate during exercise. The experimental results show that the signal-to-noise ratio of the system is improved by more than two orders of magnitude during exercise, and the accuracy of heart rate detection is increased by about three times. This study is the first to deeply integrate topological photon structures with wearable biomedical sensing, providing new ideas for the next generation of intelligent health monitoring and opening up new paths for the application of topological physics in biomedical engineering.
