Fabric Glove for Measuring the Strength of Fingers And Hand Muscle

Abstract

This project aims to design a wearable, flexible physiotherapy hand glove. Because the hardness facing the physiotherapist to diagnosis the problems in hand muscle, evaluating the treatment process. So the needed to make the device that wearable, portable to measure the force of fingers increase. This device consist of five force sensors (FSR 402) that is resistive sensor the resistor decrease with the force to measure the press force of finger, microcontroller (atmrga8) to process signal from sensor and calculate the force for every finger, LCD display to display the result from microcontroller and power supply unit to supply all components in circuit, all components sewed and connected in glove using conductive thread to fabricated the circuit to make the circuit flexible and wearable. Determine the normal ranges and abnormal ranges to any individual finger by measuring the force of fingers to thirty normal people, to measure the grip force (pinch grip, support grip, crush grip) calculate the average of force for five fingers, after complete the design experiment in physiotherapy clink for ten abnormal people during four sections the result obtain from device approximately the result obtain from physiotherapist . The design is comfortable for long term wear, portable, low power consumption, easy to use, low cost
