Application of 3D printing materials is increasing in the recent bio-medical engineering applications. Neglectful attitude toward body posture could bring the formation of spinal diseases. Improver posture during the working process induces the pain at the lower back and pectoral kyphosis. Disregard of treatment at the initial stage will further deteriorate the spinal disorder and force surgical intervention. The paper discussed several important factors together with the 3D printed spine. Thereby, this paper purpose corrector device, which intended to adjust the posture of the spine in daily life and form proper posture habits for the user. The device is equipped with a flex sensor, which detects forward spinal bending, whereas the IMU sensor measures the side motion of the body. The novel fluid-driven mechanism carries out the motion of the spinal skeleton. The origami-inspired skeleton is capable of imitating the movement of the real backbone. Under negative pressure, the skeleton constructs correct spine curvature. The algorithm inside the microcontroller processes data from the sensor and controls the actuator. A simple manufacturing process makes the design suitable for customized production.
