OVERVIEW
EMG sensor EMGsens - one-channel extremal lightweight wireless sensor for surface electromyography and moving control.
Sensor is intended use for acquisition of EMG and 3D
acceleration events and transfer it to PC or mobile device.
EMGsens can be used for education, research and development in EMG, brain-computer interface, rehabilitation, biofeedback, neuromarketing, neurogaming.
АDVANTAGES
- 6 grams,
- fixations directly to skin by disposable double sided strap tape with different adhesives,
- native EMG up to 5 kHz sampling rate or envelope EMG,
- 3D accelerometer and smart event,
- in-build electrodes or external disposable standard electrodes,
- BLE wireless for PC and mobile application.
SOFTWARE
SDK for software development for PC and mobile applications is provided by the manufacturer upon request.
Up to 18 sensors EMGsens can be integrated in the system of simultaneous registration of EMG.
