BTS-FreeEMG Portable Electromyography - Wireless Electromyography Signal Measurement

BTS FREEEMG 300

 

Completely wireless and portable electromyography device

　　

 

The birth of BTS FREEEMG 300 represents the arrival of a new generation of wireless technology electromyography devices!

 

BTS FREEEMG 300 showcases innovative breakthroughs in dynamic electromyography analysis technology

　　

 

Through innovative completely wireless technology, the BTS FREEEMG 300 uses 16 sets of wireless electrodes weighing only 9 grams (including battery) to transmit signals via wireless network to a lightweight receiver (only 360 grams), allowing patients to carry it with them, place it on a table, or have it stored by doctors.

With extremely lightweight completely wireless electrodes, not only does it allow subjects to wear it comfortably without obstruction, but it also performs closer to real conditions. Additionally, due to the miniaturized and shape-variable surface electrodes, it is suitable for any part of the body and all forms of movement (walking, running, jumping, etc.), without needing to change the subject's habitual movement patterns. It uses environmentally friendly long-lasting rechargeable batteries and can continuously record data for several hours.

BTS FREEEMG 300 can be paired with the specially developed smart and user-friendly analysis software - BTS Myolab, to capture and visualize electromyography signals and automatically process them into reports. The flexibility of using BTS Myolab allows researchers to conduct further analysis, such as local muscle fatigue measurement and muscle contraction calculations. If you require more in-depth analysis, you can also choose to pair it with EMG-Analyzer or EMGenius analysis software.

 

Operation diagram:

 

Functional features	Advanced software	Optional
The surface electrodes are extremely delicate, weighing only 9 grams. Completely wireless, quick to wear, and does not obstruct movement. Electrodes are self-adhesive with gel, no tape required. It has a 24-hour continuous monitoring mode. Can use 16 electromyography measurement points, two sets of eight-point foot pressure measurement groups, and eight limb angle or accelerometer sensors. 4kHz signal, 16Bit resolution, clear signals without interference. Built-in memory, unaffected even if the WiFi signal suddenly drops during the experiment. Intuitive touch screen operation. The wireless electrodes and receiver can transmit signals up to 50 meters away, and the distance between the receiver and workstation can reach 350 meters.

Portable completely wireless surface electromyography device

BTS EMG-Analyzer is a complete analysis software for electromyography analysis, including built-in modules developed for various research purposes: clinical assessment, sports and scientific research work: plyometric training, gait analysis, fatigue analysis, isokinetic strength analysis, etc.

In addition to built-in modules, EMG-Analyzer also has a fast and user-friendly graphical interface, allowing users to develop new modules without needing to understand complicated programming languages.

BTS EMGenius is an application analysis software for evaluating cyclical motion functions, such as gait cycle assessment, or actions like 'grasping', 'sitting down and standing up', 'hand flexion and extension', 'reaching for objects', etc. BTS EMGenius also features a simple and intuitive operating interface, allowing users to quickly get started and achieve maximum work efficiency immediately.

Application areas

BTS FREEEMG 300 can be used in scientific research, sports training, occupational injury medical treatment, masticatory studies, neurology, orthopedics, such as: assessment of neurological and surgical conditions, evaluation of drug therapy, assessment of movement deficiencies, corrective medicine, rehabilitation tracking, optimization of sports training methods.
