Wireless shoe in-sole system implementation for biomedical applications

Abstract

WIRELESS SHOE IN-SOLE is a system to measure the orientation and pressure field that acts between the foot and the support surface during everyday activities. Information derived from such pressure measures is important in posture and gait research to analyze the biometric identification, footwear design, lower limb problems, rehabilitation, health diagnostic and others. This research focuses on the development of a portable shoe integrated with wireless and recent electronic based system. It goes with the custom design package includes pressure sensor, Arduino Uno microprocessor, XBee wireless signal transmission, ultrasonic, Inertia Measurement Unit (IMU) and power supply unit. The shoe system was tested and prove to satisfy the human movement analysis based on gait parameters which include. foot mapping pressure behavior. The system focuses on the biometric application and diabetic foot pressure point. From this research, it is found that the system was able to measure the movement parameter wirelessly with ease and efficient.
