Easily add EKG signal recording to your physiological measurements with the Trigno™ EKG biofeedback sensor. This biofeedback sensor is ideal for research involving physical activity, such as studies for childhood obesity, home monitoring and performance athletics. The Trigno™ EKG biofeedback sensor will connect to industry standard snap lead electrodes and can be easily and reliably fixed to the skin with Trigno™ Skin Interfaces.

Using Trigno™ Smart Sensor Technology, EMGworks software will automatically identify EKG biofeedback sensors and configure the interface for easy processing of heart rate, heart rate variability and similar functions. The onboard accelerometer can be used to gauge body movements or to identify subtle chest movements corresponding with breathing rate. Trigno™ Wireless EKG biofeedback sensors will function seamlessly with Trigno™ Lab and Trigno™ Mobile systems

The Trigno™ Wireless EMG Systems are battery-powered biofeedback devices that enable researchers and clinicians to acquire EMG and related signals from subjects for biofeedback purposes. They are intended for relaxation training and muscle reeducation. Interpretation of the EMG and supporting signals by a qualified individual is required.
