Biosignal sensors and converters

Biosignal sensors is an analytical device for detection of a substance that combines the biological component and detector element physicist.

A sensor (detector) measures a physical quantity and converts it into a signal.

Biosignal is a summarizing term for all kinds of signals that can be (continually) measured and monitored from biological beings. The term biosignal is often used to mean bio-electrical signal but in fact, biosignal refers to both electrical and non-electrical signals.
 * Sensor only detects the presence of physical and biological signals. But we need the converter which can turn signals to be readable by an observer or by an electronic instrument.
