Description

Unique Oxide-semiconductor Sensor

>> Detection mechanism

When the oxide having the property of n-type conductivity is open to the atmosphere, it decreases the number of electron affecting on electrical property by the adsorbed oxygen and results in increasing the resistance. And, afterwards, if the specific gas (reducing gas) exists in the atmosphere, it reacts with the adsorbed oxygen and increase the electron in the oxide, resulting in decreasing the resistance.

So to speak, the electrical property of the oxide is getting changed when a specific gas is exposed from the outside and our sensor can analyze the gas concentration from the variation of quantity.
