摘要

在发达国家，背痛是最常见的健康问题之一。压力和不良的习惯，比如不良的姿势，往往是背后的原因，所以强烈建议通过姿势卫生来预防它。基于压阻式或光学弯曲传感器或惯性传感器的背部姿势测量系统已被报道。本文提出了一种基于8个加速度计，通过I2C总线连接到一个提供无线通信的小板上。数据被收集并发送到PC进行分析和警告。脊柱被建模为一个运动链，其中每个部分都有一个相关的加速度计，并且脊柱的3D表示易于解释数据。

Accelerometer Array and Method to Obtain a 3D Representation of the Spine Posture

Back pain is one of the most common health problems in developed societies. Stress and bad habits like having bad postures are often behind, so postural hygiene is highly recommended to prevent it. Systems to measure back posture based on piezoresistive or optical bend sensors, or on inertial sensors have been reported. This paper presents one based on eight accelerometers connected through I2C bus to a small board that provides wireless communication. Data is collected and sent to a PC for analysis and warning. The spine is modelled as a kinematic chain where each segment has an associated accelerometer, and a 3D representation of the spine is obtained for easy interpretation of data.
