| Detailed Description | The MEMS alcohol gas sensor utilizes MEMS technology to fabricate a micro-hotplate on a Si substrate. The gas-sensitive material used is a metal-oxide-semiconductor (MODS) material with low conductivity in clean air. When the sensor is in a gaseous environment, its conductivity changes with the concentration of the detected gas in the air. The higher the concentration of the gas, the higher the sensor's conductivity. A simple circuit can be used to convert the change in conductivity into an output signal corresponding to the gas concentration. |
| Main Applications | It is suitable for detecting ethanol vapor in locations where consumer electronics products such as mobile phones and computers are used; it is also suitable for monitoring alcohol consumption by motor vehicle drivers and other personnel engaged in high-risk operations. |
