“…The second most commonly used sensors are IMUs and sEMG sensors. IMUs are often found in exoskeleton designs and commercialized armbands, such as the Myo armband ( Ren et al, 2018 ; Cote-Allard et al, 2019 ; Su et al, 2019 ; Gardner et al, 2020 ; Viekash et al, 2021 ; Wang, 2021 ), while sEMG sensors are mainly used to measure upper-limb movements with armbands ( Cote-Allard et al, 2019 ; Young et al, 2019 ; Chen et al, 2020a ; Chen et al, 2020b ) and lower-limb movements with sEMG electrodes ( Kilic and Dogan, 2017 ; Kopke et al, 2020 ; Coker et al, 2021 ; Feleke et al, 2021 ; Viekash et al, 2021 ; Wen and Wang, 2021 ). IMUs, which measure body acceleration and angular rate, offer the advantage of being unobtrusive, portable, and relatively easy to use, making them ideal for real-time, dynamic motion tracking.…”
