A study on the human grip force distribution on the cylindrical handle by intelligent force glove(I-force glove)

Abstract

This study tested grip force on cylindrical handles to evaluate the relationships between handle diameter (50-75 mm diameter handles), perceived comfort, finger and phalange force distribution. The force glove system was used for development and estimation of various products. It is system for measurement occurred forces when subject grip the objects. It is consists of sensor assembly with 46 cells and 2 wireless storage devices. The maximum grip force was highly correlated to the weight and diameter of the subject. Maximum grip forces applied to the type 1, 2, 3 and 4 were about 12 N, 9 N, 6.1 N and 1.4 N, respectively. It was tend to increase the maximum force at the large diameter than small diameter in the same weight.

Design of grip strength measuring system using FSR and flex sensors using SVM algorithm

“…Lee et al [6] proposed an approach to determine the tip force applied by fingers called grip force glove measurement system. It was designed to measure the force applied on muscles and joints.…”

Dataglove-based interface for impedance control of manipulators in cooperative human–robot environments

“…Most of the pressure sensors used in hand-centered applications are of piezoresistive type [36][37][38][39][40]. The main advantages of these sensors are the good relation between cost and precision as well as the small thickness, which allows the sensors to fit in a dataglove with minimal interference during the hand motion.…”

“…The main advantages of these sensors are the good relation between cost and precision as well as the small thickness, which allows the sensors to fit in a dataglove with minimal interference during the hand motion. Integrating pressure sensors into dataglovebased systems is a proven approach for studying manipulation [36,37] and contact tasks in humans [39]. Additionally, pressure sensors can be integrated into robotic hands [41] to detect contact forces.…”

“…Most of the commercially-available FSR have sensing areas smaller than an average fingertip [42,43]. Consequently, previous hand-grip studies by Sato [44,45], Castro [36] and Lee [37] have used two different approaches to overcome this limitation. The simplest approach comprises a straightforward conversion from voltage to force, regardless of the dimensions of each finger segment; this procedure was proposed by Castro [36] and Lee [37].…”

The simplest approach comprises a straightforward conversion from voltage to force, regardless of the dimensions of each finger segment; this procedure was proposed by Castro [36] and Lee [37]. The output voltage of a given FSR is measured and then converted to a force contribution using the prior calibration data that relate voltage to force.…”
