The Pre-Study of Development of Smart Shoe with Musculoskeletal Injury Prevention and Monitoring System: Selection of Plantar Pressure Sensor Location and Development of Prototype

Objective: The purpose is to develop smart shoes with sensors that help prevent musculoskeletal disorder of individual workers using ICT convergent technology. Background: This study intended to develop an intelligent shoe platform for analysis of musculoskeletal disorder prevention by analyzing working conditions and postures of musculoskeletal disorder, securing biomechanical database on characteristics of consumers demanding prevention of musculoskeletal disorder, and developing hardware module and platform. Method: The positions of the pressure sensors in the smart shoe were cells 3, 5, 28, 29, and 30 on the fore-foot, cells 70 and 71 on the mid-foot, and cells 83, 84, 90, and 92 on the rear-foot; the module was inserted in the rear-foot area. For the sake of weight reduction and impact absorption, injection phylon was used. Rubber materials were used for the outside of the outsole to prevent slippage. For easy insertion of the module, the vera and the eyelids on the upper were designed to be long and deep. After the shoemaking process was finished, a translucent mesh material was used for easy removal of the midsole. Results: By doing so, inserting the module became easier; the module's accuracy and pressure dispersion improved as well. Conclusion: Working postures that induce musculoskeletal disorder can be analyzed easily by adding smart function to work shoes through existing smart devices. Application: The system can be utilized as a solution to prevent and manage musculoskeletal disorder more efficiently.
