Wireless EMG with Internal IMU
Electromyography (EMG) measures the muscle response or electrical activity by way of a nerve’s stimulation of the muscle. In particular, Surface EMG signals are recorded by non-invasive electrodes on the surface of the skin above the muscle to assess muscle function and understand how well the brain and musculoskeletal system are coordinated. Surface EMG is an important part of physiology and biomechanics research and has also been developed as a useful evaluation tool for rehabilitation, sports performance, and ergonomics.
Noraxon's Ultium EMG sensor system is a multi-modal device that delivers high-fidelity data and flexible measurement options. Ultium EMG sensors sample up to 4,000 times per second, synchronize in real-time, and demonstrate low baseline noise (<1 μV RMS) with minimal native artifacts. The implementation of IMU enables you to record both EMG and movement data.
The system features a variety of patented SmartLeads, which transform the EMG device into a versatile sensor for virtually any type of kinesiological data, and supports complete data recovery with Lossless technology. Each Ultium sensor includes lifetime battery replacement.
