EMG Measurement Device for Human-Robot Interfaces Using Metal-Rubber Electrode Arrays and Shielded Amplifiers

This technology is an interface system for human-robot interaction that acquires electromyography (EMG) signals using a metal-rubber electrode array—composed of elastic material and metal particles—integrated into a body-hugging wearable device. It utilizes ultra-short amplifiers within metal shielding to eliminate noise and controls robotic devices based on measured waveforms and signal propagation path information.

Limitations in human neural potential measurement technology have made it difficult to implement accurate bidirectional human-robot interfaces, particularly resulting in low data precision in environments requiring high-sensitivity measurement, such as rehabilitation therapy and virtual reality.

This technology enhances body contact through elastic metal-rubber electrodes infused with metal particles, suppresses noise with metal shielding, and determines the temporal and spatial propagation paths of EMG waveforms in real time. It can be applied to rehabilitation therapy, prosthetic control, and virtual reality interaction, significantly improving the reliability of human-robot interaction through precise biosignal acquisition.
