What it does
A smart patch that predicts heat stroke risk 15-30 minutes in advance through comprehensive monitoring of environmental temperature, humidity, and physiological state, triggering LED and vibration alerts
Your inspiration
Global extreme temperatures have severely impacted frontline workers, causing numerous deaths. We witnessed the urgent need for scientific protective measures after seeing high-temperature working groups exposed to dangerous environments without effective early warning systems. The inspiration came from the critical gap between rising heat-related mortality rates and lack of intelligent preventive solutions for vulnerable workers
How it works
The device uses advanced WBGT model algorithms to analyze environmental data and physiological sensors. It features innovative collarbone wearing method for ergonomic comfort, exclusive algorithm advantages for accurate heat stroke risk assessment, and industry-leading 89%+ early warning accuracy. The multi-layered structure includes photovoltaic coating, LED light strip, vibration motor, MCU module with sensor cluster, shape-memory alloy mesh, kinetic piezoelectric crystals, and medical silicone base
Design process
Our design process began with extensive research on heat-related mortality data from PLOS Medicine studies (1990-2019). We conducted simulation experiments using the Wet Bulb Globe Temperature model, comparing high-quality sensors versus traditional methods. Through iterative prototyping, we developed the unique collarbone attachment mechanism for hands-free operation and long-term comfort. We integrated dual power systems with intelligent energy switching capabilities, combining kinetic energy harvesting with solar charging. The comprehensive early warning algorithm was refined through multiple testing phases, achieving industry-leading accuracy. Each component was carefully selected for reliability and real-world application scenarios
How it is different
Three unique innovations distinguish our design: 1) More reliable product design with innovative collarbone wearing method that frees hands and provides ergonomic long-term comfort; 2) Pioneering comprehensive early warning method with 15-30 minute advance prediction and 89%+ accuracy exceeding traditional approaches; 3) First switchable dual power system with intelligent energy switching and zero-maintenance battery that stores excess energy for continuous operation without replacement needs
Future plans
We aim to support government labor protection policies focusing on high-temperature worker protection mechanisms. Plans include expanding hardware capabilities through surface-mount installation of low-power Bluetooth modules for remote monitoring and coordinated dispatching. We will develop city government oversight platforms and integrate with ERP/MES systems for comprehensive workforce management. Future iterations will enhance the dual power system efficiency and explore applications in mining, construction, and outdoor industries
