Abstract :

Accurate measurement of muscle activity is essential for biomedical engineering, rehabilitation, and prosthetic development. This study investigates the use of High-Density Electromyography (HD-EMG) to validate in the future a novel THz-based epidermal electronic system. HD-EMG, known for its high resolution and detailed muscle activity analysis, was employed on the Musculus flexor carpi radialis to detect innervation zones. The experimental setup included isometric contractions at 30 % and 60 % maximum voluntary contraction (MVC), recorded using HD-EMG grids. Results showed consistent 180- degree phase shifts between specific channels, indicating the presence of innervation zones. These findings support HD-EMG as a reliable ground truth for validating advanced epidermal electronic systems. Future research should involve a larger and more diverse sample and explore additional features of muscle activity, including the observation of zero lines and various MVC levels.
