Design and Manufacturing of Gloves for Intelligent Quantification of Hand Vibration

This research paper aimed to design and manufacture a sample of motion recording gloves to measure angles and quantify the amount of vibration of the finger joints to obtain a suitable criterion for measuring the amount of hand vibration. This glove can record the intensity of vibration, and by connecting to a computer, it can provide motion and vibration signals in the form of diagrams. The device's hardware includes an ATmega32 microcontroller, an LCD, and six bending sensors used in gloves. The present research used LabVIEW software to show online charts. After repeated tests and optimization of the device, samples were taken from 13 people with hand tremors (patients) and 9 people without hand tremors (healthy). In this sampling method, patients were evaluated in three states of displacement, concentration, and position. After recording the samples, processes were performed to extract the hand movement signal diagrams and variables to differentiate between people in the best way. The classification performed in this study between the two groups of healthy and patients showed that experimentally this system had a difference of 2.5 to 3 times between patients and healthy people in 22 people using the average speed feature. This device will help physicians in clinical diagnoses. It was also found that the best diagnostic examination by this device occurs in the parameter of average speed and position.
