| Title: Bulk Acoustic Wave Metal Oxide Gas Sensors | |
| Abstract: We have proposed and reported the bulk acoustic wave metal oxide gas sensor, which is capable of enhancing the metal oxide gas sensor’s sensitivity by at least one order of magnitude by utilizing the ultrasonic molecular manipulation technology. In the sensor system, a bulk acoustic wave is employed to drive the target gas molecules to the sensing layer to promote the oxidation-reduction reaction between target gas molecules and reactive oxygen species on the sensing layer surface. It provides a new way to effectively enhance the sensing resposne of a conventional metal oxide gas sensor. In this report, we give the detailed sensing characteristics and working mechanism of this type of gas sensor, as well as its potential applications. | |
