Sensing Wear for Multi-channel sEMG Acquisition

초록

The paper proposes a sensing wear to measure surface electromyography(sEMG) signals from the human upper body. The sensing wear has several benefits such as it does not have any side-effects for skin, it has a merit of wearability, and it is lightweight. The developed sensing wear consists of two parts such as a conductive area using silver-coated yarn including electrodes and conductive paths, and a non-conductive area using synthetic yarn for the body part. Thus, users are easily able to wear the sensing wear, unlike wet and dry type electrodes. In order to verify the performance of the sensing wear, we conduct measurement experiments for sEMG signals acquisition. Experimental results showed significant differences in 16 channel sEMG signals (p<.001) according to three kinds of motions.
