Biosuit Sensors

The FETRI biosuit represents a revolution in the way sports training is approached, thanks to its sophisticated series of sensors that capture precise data in real time, providing an objective view of the athlete’s movement and physiological variables. Below, we detail some of the advanced sensors incorporated in this innovative biosuit:

Internal exercise load sensors

They measure key biomarkers of the athlete in various situations, whether during exercise or in everyday life.

They include heart rate (HR), heart rate variability (HRV), electrocardiogram (ECG), body temperature, electromyography (EMG), lactate levels, muscle oxygen (SMO2), and glucose levels.

External load sensors

They use accelerometers and gyroscopes to provide quantitative and qualitative information about the athlete’s movement and the integration of a global positioning system (GPS) to record the location and route during training or competition.

Training and physical activity enhancers

It incorporates the best electrical muscle stimulation (EMS) system to meet specific strength and cardiorespiratory capacity objectives, a technology that contributes significantly to improving sports performance.

Body composition sensors

They allow measuring and controlling the evolution of the athlete’s body composition at an acute and chronic level.

It also stands out for the use of bioimpedance to obtain data on muscle mass, fat mass, and their relationship with sports performance.

Online communication

It has direct communication through a SIM card and allows data transmission in real time, facilitating a constant connection with the coach or technical team.

The combination of these advanced sensors not only provides a detailed understanding of the athlete’s performance but also enables personalized adaptation of training loads. Additionally, the online communication capability allows for constant monitoring, facilitating immediate feedback and informed decision-making to optimize training and improve athletic performance.

Altogether, the FETRI biosuit represents an advanced technological tool for the athlete and marks a milestone in the convergence of innovation and excellence in the field of triathlon.
