Design of Intelligent Monitoring System for Knee Joint

Abstract

Combined with physical modelling, motion capture and microprocessor technology, a human knee joint intelligent monitoring system based on nine-axis attitude angle sensor WT901 is developed. The overall design of the system and its hardware and software design are completed. The system adopts STM32 to improve the practicability of the system, use App to enhance the human-computer interaction capability. The results of the system tests indicate that the system realized accurate measurement of knee-bending angle and pressure. In addition, the system can also warn of sports posture errors and knee fatigue, and it is wearable and has low energy consumption.
