Biosignals are all around us and inside us. They help researchers understand how the human body works in real time. But beyond their role in labs and clinics, biosignals also come with some fascinating facts. Here are seven that might surprise you:
1) Your Skin Can “Talk” Without You Saying a Word
Electrodermal Activity (EDA) measures changes in skin conductance, which often reflect emotional or stress responses. That’s why lie detectors use it, your skin reacts faster than your words.
2) Brainwaves Can Control Machines
Through EEG signals, it’s possible to control devices with your mind. This is how brain-computer interfaces work, helping people with motor disabilities use computers, wheelchairs, and more.
3) Your Heart Doesn't Beat at the Same Pace All the Time
Even at rest, your heart rate naturally changes from beat to beat. This variation, called HRV (Heart Rate Variability) is linked to stress, fitness, and even emotional regulation.
4) Muscle Signals Can Be Picked Up Without Touching the Skin
With the right equipment, EMG sensors may even detect muscle activity through clothing, useful in sports and prosthetics development, especially in real-life conditions.
5) Respiration Signals Can Reveal Sleep Patterns
Breathing rhythms are used in sleep research to track sleep stages, detect disorders like sleep apnea, or study the effects of relaxation techniques.
