Method and device for determining specific gas or ion concentrations |
| abstract |
Gas mixture component concentration determination comprises use of a gas or ion sensitive layer (4) whose mechanical, optical or electrical properties change with gas or ion concentration. The electrically conducting layer is between two electrodes (4.1, 4.2) through which an alternating electrical field is applied. The layer consists of piezoelectric material and a means is available for its mechanical deformation. In conjunction with the layer (4) is a surface or bulk acoustic wave sensor. The layer (4) is configured so that the gas sensitive layer (4) acts as the gate of a field effect transistor. The measurement process depends on the absorption or emission of gas or ions from the gas sensitive layer changing its properties. In order to determine n gas concentration at least n measurements of the sensor voltage must be made. One or more similar sensors can be used to determined multiple concentrations. |
