While low back pain (LBP) is the leading cause of disability worldwide, its clinical objective assessment currently limited. Part this syndrome arises from abnormal sensorimotor control muscles, involving increased muscle fatigability (i.e., assessed with Biering-Sorensen test) and activation patterns flexion-extension test). Surface electromyography (sEMG) provides measures fatigue development (median frequency drop, MDF) (RMS amplitude change). This study therefore sensitivity validity a...
A new multi-material polymer fiber electrode has been developed for smart clothing applications. The conductive is optimized bipotential measurements such as surface electromyogram (sEMG) and electrocardiogram (ECG). main benefit of this its flexibility being a dry non-obtrusive electrode. It can be directly integrated into garment to make textile real time biopotential monitoring. customized wireless electronic system acquire electrophysiological signal from the fiber. receiver base station...
This work presents a system for measuring and analyzing motion, by portable electronic device flexible fiber sensor. The is composed of multi-walled carbon nanotubes (MWCNTs) its conductivity polydimethylsiloxane elastomer (PDMS) elasticity. A new sensor interface circuit was designed in this study to with the measure impedance. measured impedance data are sampled transmitted via Bluetooth laptop. characteristics wireless measurement allow an easy integration into smart garment monitor...
We present the design of a motion analysis wearable sensor based on flexible and stretchable fiber coupled to miniaturized wireless electronic circuit. The is made carbon nanotubes polydimethylsiloxane elastomer (PDMS) and, when integrated into smart garment, it enables measure multiple vital signs. performance thoroughly characterized benchmarked for detection (i.e. flexion/extension angular amplitude). measurements were performed by mean developed circuit designed interface with digitize...
Work-related upper extremity musculoskeletal disorders (WRUED) are a major problem in modern societies as they affect the quality of life workers and lead to absenteeism productivity loss. According studies performed North America Western Europe, their prevalence has increased last few decades. This challenge calls for improvements prevention methods. One avenue is through development wearable sensor systems analyze worker's movements provide feedback and/or clinicians. Such could decrease...
