Intelligent Human Body Detection System Based on Mechanoluminescence Materials for Flexible Sensors

The phenomenon of materials emitting light under stress is crucial for the development of a new generation of intelligent sensors. However, many sensor detection systems based on mechanoluminescence (ML) materials are complex and feature high luminescence thresholds. To overcome these challenges, we have developed and demonstrated a novel intelligent human body detection system leveraging mechanoluminescence sensors. Engineered for real-time monitoring of human joint movements and dental occlusion states, the system utilizes ZnS:Cu nanomaterials to fabricate flexible thin-film sensors characterized by low luminescence thresholds, heightened pressure sensitivity, and better elasticity. By integrating image processing algorithms, the system enables non-invasive and highly sensitive detection of forces exerted on teeth and joints. This research offers novel insights for the assessment of dental occlusion and joint health, thus providing a new application for mechanoluminescence sensors in the realm of intelligent medical diagnostics.
