biosignals
Biological electrical readings
Biosignals are electrical, chemical, or mechanical signals produced by living organisms that can be measured and analyzed.
The term encompasses a wide range of physiological data: brain waves (EEG), heart rhythms (ECG), muscle activity (EMG), skin conductance, and more.
Biosignals are central to medical monitoring, wearable fitness devices, and brain-computer interfaces: The headset reads biosignals to detect when you're losing focus.
