Sensor evaluation for hand grip strength

Abstract

<p>This paper discusses the evaluation of the sensors used in the hand grip strength glove. The glove comprises of flex and force resisting sensors. Force resisting sensor determines the force applied by various parts of the palm, while the flex sensor determines the flexion of the fingers. These sensors are placed in a specific position on the glove to obtain correct data when the glove is used. The glove has two modes, which are pencil grip mode and object grip mode. The sensors determine which mode the glove is in depending on the gesture made. The glove is examined using a pencil and a cylindrical object to evaluate the strength of the grip. After gripping the object or pencil, the system evaluates the force applied using the sensors. This data is transferred to a computer for further analysis using a trained model. The model was able to achieve an accuracy of 90.8%.</p>

“…The literature reviewed here is divided by the types of sensors, communication, algorithms that is used and how the gestures are outputted. In [2]- [6], the authors use a glove consisting of flex sensors. The gestures recorded by these sensors were displayed on the LCD.…”
