Abstract |
Spinal disease rate has been recently rising since people more likely are in sitting posture. If the spine is bent for a long time in an unstable position, the risk of getting spinal disorders can be increased by kyphoscoliosisc, scoliosis, lordosis and kyphosis. To diagnose your spinal conditions, you must visit specialized medical institutions, which force you to spend extra time and money. Therefore, it is necessary to prevent diseases through posture screening in daily life. In this study, the amount of impedance variation formed during sitting is measured with a conductive fiber sensor. The conductive fiber sensor consists of a matrix structure consisting of 36 nodes of 6x6 using conductive fiber, Copper tape and OHP-Film. In order to know the impedance characteristics of the sensor, check the change in the figure for a given pressure at each node and conduct pressure distribution research when sitting down. Pressure distribution plots are illustrated with intuitive interpretation through color changes. These systems determine the degree of waist distortion during user’s sitting, and research is conducted to prevent postural instability, which is the cause of spinal cord disease. |
