Fully Integrated Photoacoustic NO<sub>2</sub> Sensor for Sub-ppb Level Measurement
A fully integrated photoacoustic nitrogen dioxide (NO<sub>2</sub>) sensor is developed and demonstrated. In this sensor, an embedded photoacoustic cell was manufactured by using an up-to-date 3D printing technique. A blue laser diode was used as a light source for excitation of photoacou...
