GSR-Based Non-Invasive Monitoring
The core innovation lies in leveraging sympathetic nervous system-mediated sweat gland activity for assessing neural injury, independent of neural pathway integrity. This approach provides a non-invasive, real-time method for dynamic monitoring of physiological signals, overcoming limitations of traditional methods.
It integrates a 500 Hz high-frequency sensor, specialized conductive gel, and an Arduino UNO platform. Adaptive filtering and dynamic threshold models ensure accurate data processing and anomaly detection with minimal false alarms. The ergonomic, biodegradable PLA design enhances practicality and patient comfort.
Layered Modular Design for Robustness
The system adopts a layered modular architecture comprising three main layers:
- Perception Layer: Captures physiological signals using a high-sensitivity GSR sensor module applying a safe microcurrent.
- Processing Layer: Centered on the Arduino UNO, this layer handles data preprocessing, adaptive filtering, dynamic threshold analysis, and intelligent decision-making, also controlling alarm triggers.
- Application Layer: Manages user interaction, providing real-time display of skin conductance curves, dynamic thresholds, and abnormal event markers on computers or mobile devices, with data export functionality.
This design ensures system stability, scalability, and real-time performance across various environments, including clinical settings, home care, and rehabilitation centers.
High Accuracy and Rapid Response
Experimental results confirm the system's high efficacy:
- Accuracy: 95.20% overall correctness in state judgment.
- Precision: 93.80% proportion of correct alerts among all alarms.
- Recall (Sensitivity): 96.50% of true anomalies successfully detected.
- False Positive Rate: A low 4.30% of normal states incorrectly flagged.
- Response Time: Average 520 ± 85 milliseconds from signal exceedance to alarm activation, critical for emergency monitoring.
The system's adaptive filtering algorithm suppresses environmental noise, yielding a Signal-to-Noise Ratio (SNR) of 25.5 dB, ensuring subtle physiological changes are clearly distinguishable.
Enhancing Patient Care and Monitoring
The system offers a new technological direction for rehabilitation assessment and long-term monitoring of neural injuries. It helps overcome the limitations of traditional monitoring methods—inefficiency, subjectivity, and reliance on manual observation—by capturing stress responses to hazards like abnormal pressure, temperature, or infection for early warning.
Suitable for various environments, including clinical settings, home care, and rehabilitation centers. Its non-invasive, comfortable (biodegradable PLA finger cot), and user-friendly design makes it broadly applicable to diverse populations, including patients with spinal cord injuries, enhancing their safety and quality of life.

Simulated Abnormal Event Response
During simulated abnormal events, the system consistently detected anomalies. When external stimulation caused a significant change in skin conductance, the system promptly identified the anomaly. The system status changed, triggering both visual (LED) and auditory (buzzer) alarms within 520 milliseconds. Upon cessation of stimulation, conductance returned to normal, and the system reset, demonstrating its real-time responsiveness and reliable anomaly detection capabilities for physiological crises. This validates its effectiveness in dynamic monitoring and early warning for neural injury patients.
