A Preliminary Design of New Kyphosis Backpack With the Ability To Show Pressure and Maintain the Curvature of the Spine

The aim of this study was to design a kyphosis backpack with the ability to show the pressure and maintain the curvature of the spine for people who use backpacks for a long time. this backpack is designed with tracholambosacral brace. it is designed to distribute good pressure on the shoulder, which is suitable for all ages and has two metals to maintain the natural alignment of the spine and adjustable straps on the front of the trunk and front of the abdomen. the backpack consists of three fabric bands, an electrical circuit consisting of three bending sensors and a pressure sensor, as well as two stabilizing metals. designed to communicate between sensors in a mobile backpack (mobile app) that displays information about its degree of curvature through bending sensors. in order to display the amount of pressure, the pressure sensor also shows this information on the mobile phone. the design of this circuit and application is such that if the amount of curvature and pressure is more than the allowable limit, it informs the person through vibration so that it can maintain the normal level of the spine and also adjust the bag load. to use this feature, the application must turn on the electronic circuit, then connect to the circuit via bluetooth to establish a connection between the circuit and the mobile application. the kyphosis backpack with the ability to measure pressure and maintain the curvature of the spine designed in the present study can be used in correctional training programs, carrying classroom equipment as well as sports equipment. the warning system and display of the pressure on the spine, makes this backpack a comfortable and user-friendly backpack.
