Abstract

Walking is an exercise that can be easily started by people with weak physical strength and the elderly, which can have many effects, such as smoothing blood circulation and preventing diabetes and obesity, but walking in the right posture is important for effective walking exercise. In this paper, we propose a 3D printed TPU (thermoplastic polyurethane) pressure sensor manufactured using an electrically conductive filament rather than pressure sensors sold commecially, and using the data obtained therefrom, we implemented a system that monitors the user's walking characteristics through a cloud system and attached it to the shoe to produce a smart shoes. Since the sensor is manufactured through 3D printing, it can be freely manufactured in the desired shape and size, and can be used not only as a shoe but also as a touch sensor that can act as the skin of a humanoid robot.
