myon EMG systems
| The myon RFTDs deliver high data rate transmission quality even with weak input signals. New proprietary technologies eliminate signal overlap, false signals and other potential artifacts. The transmission algorithms acquire the signals in real time - synchronized and without offset. Latency is the same for all channels and constant at 16ms - less than half that of similar Wi-Fi systems. Zero wires - the myon system eliminates wires on the subject and speeds the examination preparation. Just connect the EMG snap leads and attach to the subject. No setup procedures, no synchronizing between transmitters and receivers, no initialization. |
Motion Lab Systems is pleased to offer myon Radio Telemetry Devices as an alternative to our traditional EMG systems for situations that require a zero wire EMG environment within a small laboratory space. A typical myon system consists on one or more myon transmitters (RFTDs) and a myon receiver. Each myon receiver can handle up to 16 transmitters - up to 32 transmitters can be supported using dual receivers.
myon RFTDs - Radio Frequency Transmitting Devices
The myon RFTDs are lithium polymer powered devices for wireless transmission of different sensor signals such as goniometers, ECG and EMG. myon RFTDs allow sensor data to be seamlessly integrated into biomechanics and sports contexts. These devices are slim and lightweight, with a minimal application surface and secure adhesive plane. They are constructed to allow precise positioning on the body. Each myon system is capable of acquiring up to 32 EMG or accelerometer channels within the laboratory environment. The myon system does not support foot switches or electrogoniometers.

Quality based on international scientific standards
The myon system utilizes advanced and well-engineered technology that guarantees high grade signal quality without artifacts at both the signal processing and transmission stages. Processing of the sensor signals with the myon RFTDs implements ISEK and other internationally accepted scientific standards, superior 5Hz to 1kHz signal bandwidth, 12-bit resolution, 4kHz sampling rate comply with the extensive recommendations of renowned scientific institutions and work groups. The full 5Hz-1kHz signal bandwidth is double that offered by other modular Wi-Fi EMG systems, while the group delay (from the subject to recording device) at 16ms is less than half the delays of similar Wi-Fi EMG devices from other manufacturers.
Small, lightweight yet long battery life
The myon RFTDs are completely wireless. Additionally no reference electrodes or additional wires are necessary. The small, slim and lightweight myon RFTDs are simply attached at the place of measurement. The proprietary radio technology of the myon RFTDs guarantees transmission distances of up to 30 metres (100 feet) - without any repeating units applied to the patient or in the vicinity. The integrated batteries in the myon RFTD's permit up to 8 hours of continuous measurement. Recharging of the batteries is very quick, after only 30 to 60 minutes, RFTDs are completely recharged and ready to be used again.
System compatibility
All myon systems produce clean analog signals suitable for most ADC (Analog Data Collection) devices and can be directly attached to any motion capture system that supports analog data collection over a range of +/-2.5V to +/-5V. All myon systems include proEMG lite software to view, capture and export EMG signals via ADC devices from National Instruments and Data Translation. The following ADC devices are supported by the myon ProEMG software.
| Supported ADC device | ADC specification |
| NI USB-6210 | 16 channels, 16-bit |
| NI USB-6215 | 16 channels, 16-bit |
| NI USB-6218 | 32 channels, 16-bit |
| NI USB-6225 | 80 channels, 16-bit |
| DT 9812 | 8 channels, 12-bit |
| DT 9813 | 15 channels, 12-bit |
| DT 9813 | 24 channels, 12-bit |
| DT 9803 | 16 channels, 16-bit |
Two versions of the ProEMG software support data capture and export from the myon system, while a third version integrates with the Vicon Nexus software to provide EMG signal processing within the Vicon data collection environment:
- ProEMG Lite. Included with the purchase of a myon system, this application lets you capture data to the hard disk, view existing data, and export data either to an ASCII file or directly to Microsoft Excel.
- ProEMG Stand-Alone. A separate application from the ProEMG Lite, this version has all the functionality of the Lite version plus all signal processing, automatic calculation, report generation and automatic processing functions.
- ProEMG Nexus. This version provides all signal processing, automatic calculation, report generation and automatic processing functions of the ProEMG version while using Vicon to sample the EMG data.
The myon system is compatible with other data collection devices and EMG analysis software applications.
