Implementation of Piezoelectric Sensor in Gait Measurement System

Gait measurement system may expose related fields for applications in sports, activity tracking, and in the treatment of specific diseases. Available technology such as image processing, force plate, and insole shoe device are showing that gait analysis is famous research study in a recent year. But the available method is more expensive with the used of wide area for experimental. Moreover, the used of image processing technique and force plate required a fix location as it need to be installed for subject recruitment. A wearable technology such as insole can help in this scenario by develop the measurement gait systems to a wide set of patients or healthy people. In this proposed project, the measurement for gait using low cost sensor is designed for gait pattern detection during walking. This present a force sensor that will designed using foot insole technique for real-time monitoring during walking. This device is made up of flexible insole with three piezo sensing elements using integrated electronic board of data acquisition, and monitoring system for data analysis. Design and development of the system is tested and the signal presented show a different force applied at different part of feet. System tested directly by performing some activity from 15 subjects who differed in body mass (range: 35–80 kg). Activity that is performs show a different signal pattern such as heel strike, midstance, stance, toe-off and walking activities. This project results have a possibility to increase the use of wearable device to capture the data with a relevant parameter as well as improve data analysis for a better system performance.
