Zinc oxide sulfur sensor |
| 摘要 |
A sulfur concentration detection system for detecting a sulfur concentration in a liquid includes a sensor having a conductive metal substrate and zinc oxide microstructures deposited on and protruding from the conductive metal substrate, a current source, and a voltage detector. An electrical resistivity of the zinc oxide microstructures is configured to change as a function of an amount of sulfur in the liquid available to react with zinc in the zinc oxide microstructures. The current source and the voltage detector are connected to the conductive metal substrate and configured to detect a change in the electrical resistivity of the zinc oxide microstructures. |

1. A sulfur concentration detection system for detecting a sulfur concentration in a liquid, the detection system comprising:
a sensor having a conductive metal substrate made of stainless steel or copper, and zinc oxide microstructures deposited on and protruding from the conductive metal substrate, an electrical resistivity of the zinc oxide microstructures being configured to change as a function of an amount of sulfur in the liquid available to react with zinc in the zinc oxide microstructures; a current source; and a voltage detector, wherein the current source and the voltage detector are connected to the conductive metal substrate and configured to detect a change in the electrical resistivity of the zinc oxide microstructures.
