The Fusion Arm Sleeve enhances the Motion Arm Sleeve by integrating EMG (electromyography) sensors with a force sensor to unlock unprecedented insights into arm performance and muscle fatigue.
Equipped with two EMG sensors on the biceps and triceps, it measures muscle recruitment, activation, and intensity, alongside force metrics like torque and strain around the elbow.
This advanced sleeve provides a comprehensive real-time profile of biomechanics and biopotentials, offering improved technique awareness, injury prevention, and performance optimization.
Force Sensor + EMG Sensors Validation
Analyzing the integration of EMG signals from the biceps and triceps alongside ADC values from the force sensor provides a holistic view of muscle activity, force application, and arm biomechanics, enabling deeper insights into performance, technique, and fatigue.
The plots add another layer of understanding to muscle recruitment on top of arm movements, delivering a detailed analysis of arm bending dynamics and muscle exertion.
