Integrated micro power frequency breath detector
Sensors and Actuators A: Physical（2016）
Abstract
•Breath sensor powered by the input bias current of an operational amplifier.•Amplifier saturation state compensated during exhalation.•Sensor attached to the integrated circuit (FBD).•High sensitivity of FBD to very weak breathing.•FBD works with digital systems without the need for signal conversion.
