Design of Plantar Pressure Measurement to diagnose the flat feet patients Plantar Pressure

Abstract

This research presented the design of plantar pressure measurement tool. The objective of this study were the plantar pressure data for assist decision doctor investigate foot disease type, that establish a measurement with high resolution and relatively accurate measurements. The development uses Force Sensing Resistor (FSR) to scanning the plantar pressure Measurement, about 15 points on feet of patients in the foot type verification analysis. The signal conditions circuit changes the resistor of FSR sensor into voltage and send to Arduino microcontroller, its processed to send out the data via Nrf24l01 wireless module for display on the monitor of the micro-computer. On the micro-computer have an algorithm for predicting the risk of patients was flat foot (fallen arches) or Hollow foot (high arches). From experiments on laboratory, the calibration method for the plantar pressure measure system was established with the use of a Foot Imprinter Harris Mat. The device from our design have feasibility for predicting the flat foot risk of patients.
