FBG Sensing Glove for Monitoring Hand Posture

Abstract: A wearable sensing glove for monitoring hand gestures and posture has been developed. The glove sensing capability is based on optical fiber Bragg gratings (FBGs) sensors. These sensors, due to their inherent self-referencing and multiplexing capability, are a value-added choice for this application. A single optical fiber would cross all the hand with Bragg structures in specific spots, as the finger joints. The functionality and performance of the glove was fully evaluated. The sensor response was linear to … Show more

“…Many solutions employ only flex sensors, which are used mainly for hand movement or hand posture acquisition. One of such solutions for hand posture acquisition is presented in [11], where the sensing glove was equipped with fiber Bragg gratings sensors, which allowed for the measurement of finger bending. Another solution used an accelerometer sensor wristband to capture arm movements [12], [13].…”

“…This device was equipped with an analogue sensor to measure the flexion of the joint, similar to a goniometer. In former studies, different sensor sets for motion analysis are described, but in most cases, the aim is different; for example, Liu et al developed a device for gait analysis [14], da Silva et al studied hand postures, which are on a larger scale compared to finger articulations [19], Ju et al [10] measured the tactile force and EMG signals in addition to finger angles to gain complex information on hand motion, but did not deal with the limits of angles, while Nicol [18] described an electrogoniometer, but the device is not suitable for the current study. In this device, the rotational axis of the potentiometer was aligned with the rotational axis of the finger joint to ensure accuracy of the measurement data.…”

“…It is already possible to find some wearable solutions capable of monitoring the hand posture and retrieving the required data, few based on electrically conductive elastomer (Lorussi F. et However, the available solutions are quite complex (Silva A. F. et al, 2011b), namely because of non-linear responses from the sensor, fragility issues or complex methods for signal processing. Still, from the existing technologies and solutions, the ones based on optical fiber sensors offer the biggest potential, when looking for performance and wearability (Lee B., 2003).…”

“…Therefore, these features make the FBGs suitable sensing elements for doing physical measurements, where a kind of displacement is available. Examples of such applications found in the literature include the measurements of strain (Grattan S. K. T. et al, 2009;Ling H. Y. et al, 2006), pressure (Peng B. J. et al, 2005;Zhang W. et al, 2009), force (Rajan G. et al, 2010;Zhao Y. et al, 2005), tilt rotation by an angle (Peng B. J. et al, 2006;Xie F. et al, 2009), acceleration (Antunes P. et al, 2011;Fender A. et al, 2008), temperature (Bao H. et al, 2010;Gu X. et al, 2006), humidity (Arregui F. J. et al, 2002;Yeo T. L. et al, 2005), magnetic fields (Orr P. et al, 2010), cardiorespiratory function (Silva A. F. et al, 2011a), hand posture analysis (Silva A. F. et al, 2011b), gait function analysis (Rocha R. P. et al, 2011) and integration on wearable garments (Carmo J. P. et al, 2012).…”
