Development of Printed Sensors for Shoe Sensing Applications

The paper presents the design and implementation of a low-cost shoe sensing system using laser-induced graphene sensors. Commercial polymer films were laser-induced to photo-thermally form graphene, which was then used as electrodes on Kapton tapes to form sensor patches. Experiments were then conducted with these sensor prototypes to validate its functionality as pressure sensors to be used in shoe sensing system. Different weights were tested with the developed system to ensure the capability of these sensor patches to be used as pressure sensing. The results look promising to be a system for monitoring the movement of a person wearing a shoe containing these low-cost pressure sensors.
