数十亿人以不良姿势使用智能手机和电脑。对脊柱姿势的粗心态度可能会对脊柱的长期健康造成危险，最终导致脊柱弯曲。忽视这一事实及其早期治疗将显着恶化脊柱健康并迫使进行手术干预。现有的研究主要集中在姿势监测系统上，而不是开发自动姿势校正系统，以通过人机界面（例如基于蓝牙的设备）通知用户。因此，本文提出了一种新的姿势矫正方法，通过促进正确的姿势习惯来自动预防脊柱疾病。具体来说，我们开发了一种流体驱动的可穿戴姿势矫正器，其骨架可以简单地使用3D打印机制造，利用传感器估计角度姿势偏差，并为纠正用户的姿势习惯提供适当的帮助。安装的传感器提供姿势弯曲的程度，控制器调节适当的信号，以提供友好的拉力，通过流体驱动执行器提醒用户。具有流体驱动工具的骨架旨在通过激活致动器来模拟脊柱姿势的运动，该致动器将流体注入（或释放）到骨架框架中并调节力以减少骨架的角度偏差。带有柔性橡胶管的 3D 打印骨架已经过实验评估，以确保通过调节气压来确保正确的驱动机制。结果发现，通过施加 0 至 101.4 kPa 范围内的气压，骨骼被拉回约 1 N 至 7 N 的力，相对于初始稳定阶段将角度最小化至 12.44∘，这导致不良姿势的最大姿势校正为 32.55% 的角度 (θ)。从上述实验中，我们确保了所提出的姿势校正器在产生向后力以自动校正姿势方面的功能。
Billions of people are using smartphones and computers with poor posture. A careless attitude towards spinal posture could be dangerous for long-term spinal health, leading eventually to curvature of the spine. Ignoring this fact and its treatment at the early stage will significantly deteriorate spinal health and force surgical intervention. Instead of developing an automated posture-correcting system, the existing research mostly focused on a posture-monitoring system to inform the users via a human interface, e.g., Bluetooth-based devices. Therefore, this paper proposes a novel posture-correction method to automatically prevent spinal disease by facilitating proper posture habits. Specifically, we develop a fluid-driven wearable posture corrector, whose skeleton can be fabricated simply using a 3D printer, to estimate angular posture deviation using sensors and provide appropriate assistance to correct the posture habit of the user. Mounted sensors provide the degree of postural bending, and a controller regulates the appropriate signals to provide a friendly pulling force as a reminder to the user through a fluid-driven actuator. The skeleton with a fluid-driven tool is designed to mimic the motion of the spinal posture by activating the actuator, which injects (or releases) the fluid into (or from) the skeleton frame and regulates forces to reduce the angular deviation of the skeleton. The 3D-printed skeleton with a flexible rubber tube has been experimentally evaluated to ensure proper actuating mechanism through the adjustment of air pressure. It is found that, by applying air pressure in the range of 0 to 101.4 kPa, the skeleton is pulled back approximately 1 N to 7 N forces, minimizing the angle up to 12.44∘ with respect to the initial steady stage, which leads to a maximum posture correction of 32.55% angle (θ) of poor posture. From the above experiments, we ensure the functionality of the proposed posture corrector in producing backward forces to correct the posture automatically.
