Flexible EMG Detection – Multi-purpose Sensor for Numerous Research Applications

Quote Request

The Trigno™ Flex sensor is an EMG biofeedback sensor designed to be used exclusively as a component of the Trigno™ EMG System. The sensor is designed to accommodate research needs requiring an expanded bandwidth range (10-850 Hz) or an expanded amplitude input range (22mV rti). The original recommended parameters of the standard sensor (20-450Hz, 11mV rti range) are still available as well. The specifications below identify the choices available.

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.
