1-channel electromyograph

2-channel12-channel3-channel

Description
Portable wireless surface electromyograph (sEMG) for simultaneous acquisition and stimulation across 1–16 channels, designed for clinical assessment and dynamic monitoring.

Main features

• Simultaneous multi-channel EMG: Acquire and record bioelectric signals on 1–16 channels.
• Neuromuscular stimulation: Stimulate up to 16 sites with adjustable current and pulse-width parameters.
• Wireless connectivity: Wi‑Fi transmission for flexible clinical and field use.
• Portable power: Long-life lithium battery for extended mobile operation.
• Intuitive operation: Real-time voice and text prompts for guided use and monitoring.

Overview
Combining Wi‑Fi wireless transmission with synchronous multi-channel acquisition, the device captures precise sEMG signals and offers robust anti-interference performance. It supports quantitative evaluation of muscle strength, tone and injury, and enables gait analysis and multimedia game-based rehabilitation training. The system supports multiple acquisition combinations (e.g. 16+16, 14+2, 12+4, 8+8, 8+2, 8+4) to adapt to varied clinical and sports-medicine scenarios.

Applications
Suitable for rehabilitation therapy, sports medicine, gait analysis, neuromuscular assessment and home/dynamic monitoring where portable, multi-site EMG acquisition and stimulation are required.

Advantages

• Improved patient engagement: Integrates biofeedback with multimedia game training to increase compliance.
• Simplified setup: Integrated electrode cables reduce donning time compared with split-cable systems.
• User-friendly workflow: Modular software layout and built-in standardized evaluation schemes reduce training time for clinicians.
