摘要：

Attempts have been made to enhance the gas sensitivity of semiconductor metal oxides to trimethylamine (TMA), which is a typical offensive odor. The resistance level in air, catalytic activity and thickness of the sensor material are found to be important sensitivity-determining factors. Further investigations have revealed potential advantages of TMA gas sensors in detecting fish freshness.
