本研究开发了一种传感器系统，该传感器系统利用位于伤口周围的周围电极阵列测量电阻抗，并使用断层扫描结合光谱学方法估计深度并对该区域小区域组织的差异进行分类。该系统旨在集成到敷料中，以减少不必要的敷料移除。在人体试验中，使用随机森林分类器（94.4%准确度）检测保湿剂施加面积，并且每10分钟之间的保湿剂施加面积差异显著（p<0.05）。该研究证实了概念证明，即该系统可以监测人体皮肤的变化，而无需将传感器连接到目标区域，并指示已发生变化的皮肤区域。
This study developed a sensor system that measures electrical impedance with a surrounding electrode array that is located around the wound and estimates the depth and classifies the difference in tissues of small regions in the area using tomography combined with spectroscopy method. The system is designed to integrate into the dressing to reduce unnecessary removal of dressings. In the human trial, moisturizer applied area was detected using Random Forest classifier (94.4% accuracy) and differences between every 10 minutes were significant in moisturizer applied area (p<0.05). The study confirmed the proof of concept that the system can monitor the change in human skin without attaching the sensor to the target area and indicate the skin area that had changed.
