Sistema de plantillas instrumentadas "PIEZOMED" destinadas a la valoración del calzado

Abstract

In Colombia, there haveńt been reports about the development of an Insole Instrumented system for the footwear industry that contributes in biomechanical design of their models, improving comfort and productivity during design and production of footwear. This article describes the development of the first phase of the instrumented insole system "PIEZOMED", which has a pair of insoles size 41, evaluated in a male footwear model casual of the Company VÉLEZ® the insoles were instrumented with piezoresistive sensors, which had a good linear answer. This first prototype was built wired, looking for a functional design and adaptable for future valuations in footwear. The Software was developed in two parts, the acquisition module, in Labview platform, and the processing and visualization module, in C#.Net. In this phase, the system was built and its performance was tested in casual footwear and visualizing as results: 2D view dynamic, 3D view dynamicm, numeric map, P Vs. t graph, and F Vs. t graph. In a future phase, the system will be developed wireless, with an increased resolution (number of sensors) and tested in a considerable quantity of subjects to evaluate the reliability and validity of the system in contrast with a commercial system. The main aim is to use these insoles for footwear valuation, to support the industry, looking for biomechanical, comfortable, and fashion footwear. © Springer-Verlag Berlin Heidelberg 2007.
