康复锻炼用姿态监测智能T恤的研究

Study on Posture Monitoring Smart T-shirt for Rehabilitation Exercises

针对脊柱疾病的患者康复锻炼期间需要监测生理参数,采用无线可穿戴T恤进行姿态监控。患者姿态通过直接缝制在织物上的Z字型感应式传感器进行采集,然后通过信号调理电路放大和滤波,最后经微控制器处理并通过蓝牙低功耗模块发送至PC终端或Android手机终端的康复监控管理系统。与在医师指导下的光学系统所获得的标准姿态数据进行对比,通过微电机发出的震动强弱不同的信号,提醒患者矫正自己的体位。通过4位实验者进行的实验证明:智能T恤能够与光学系统所获得的数据进行比较,产生可靠的数据,能够帮助患者形成正确的锻炼姿势,恢复正常的生理状态。

Physiological parameters of patients with spinal diseases need to be monitored during rehabilitation exercise,so a wireless wearable T-shirt is adopted for posture monitoring. Patient posture data are collected by Zshaped inductive sensor which is directly sewn onto the fabric. Then,the data are amplified and filtered by signal conditioning circuit. Finally,those data are sent to rehabilitation monitoring and management system at the PC or Android mobile phone terminal via Bluetooth low energy module after micro-controller processing. The system compares with the standard posture data obtained by optical system under the guidance of the physician and reminds patients of correcting their position through the signals with different vibration strength sent by micro-motors. The experiment involving 4 patients shows that the smart T-shirt can generate reliable data through comparing with the data gained by optical system and can help patients form correct postures and recover normal physiological status.
