Quantifying the Contributing Factors toward Signal Fatigue in Nanocomposite Strain Sensors

“…3 These advances in research and their processability are quickly leading to the realization of these materials even facilitating future robotic technologies. 4 In order to enable these lofty yet very realistic aspirations, nanocomposite strain sensors must display a large sustainable electromechanical response over a wide working range (i.e., large working factor). 3 Ideally, these sensing materials will have a signal that changes linearly with strain to accommodate performance metric extrapolation and signal processing.…”

Application of Unconditioned Nanostructured Thermoplastic-Based Strain Gauge Sensor in Wearable Electronics

“…These results are particularly relevant when compared to similar works in literature considering that we used only 3 sensors without a dedicated study to the optimization of the size, the number and the position of the sensor themselves. In fact, even if F-Score and accuracies can be on comparable levels, these results often come at the cost adopting invasive solutions [45][46][47], a large number of sensors [45] or recognizing a very limited set of gestures [48][49][50]. These considerations let us estimate that the obtained results just scratch the real potential of an appealing technology for studies and applications related to human body movement analysis such as gesture recognition, gait analysis, motion tracking, etc.…”
