This study evaluates the mapping accuracy between textile stretch sensor data and surface electromyography (sEMG) signals using Multilayer Perceptron (MLP), Convolutional Neural Network (CNN), Residual (ResNet) models. Data from forearm, biceps brachii, triceps brachii were analyzed Root Mean Square Error (RMSE) R2 as performance metrics. ResNet achieved lowest RMSE (e.g., 0.1285 for brachii) highest (0.8372), outperforming CNN (RMSE: 0.1455; R2: 0.7639) MLP 0.1789; 0.6722). The residual learning framework of effectively handles nonlinear patterns noise, enabling more accurate predictions even low-variability datasets like brachii. showed moderate improvement over by temporal features but struggled with datasets. MLP, baseline model, demonstrated R2, highlighting its limitations in capturing complex relationships. These results suggest potential reliability to sEMG signals, showing promising within scope this study.
