The development and verification of a piezoresistive foot pressure recording device

This study has developed a plantar pressure sensing device by utilizing the piezoresistive sensor array that has adopted Nano-technology and Screen Printing Technology. This sensor array has high linearity (>0.95), high repeatability (<;5%), large range of pressure (2.54Mpa) and the high bending fatigue tolerance. Comparing the specification of this piezoresistive sensor array with other similar device, it can be considered as the thinnest sensor array, highest range of pressure and greatest number of sensors among the commercialized products.
