A dynamic monitoring and identifying system of Fe2O3 series gas sensors for the research of electronic nose is introduced. The system has 6 channels to input 0~2.5V voltage signals, measures system temperature, makes thermoregulation for sensor with hardware and has LCD screen and voice function. The heating circuit using TL494 chip and PWM mode is realized. Offline and online identification is realized. The hardware design is based on 16 bits MSP430F149 microcontroller. The software design for digital acquisition and identification based on Windows operating system is compiled by Visual Basic 6.0. The test results show that friendly interface, simple operation, accurate data, reliability and stability are obtained. The real-time monitoring for all of the sensors in aerometry or identification can be realized by BP ANN.

There are no sufficient holes to follow the negative AC bias stress when high frequency is chosen. Due to the operation of the flat panel displays is under AC signal, therefore we discuss the degradation under DC and AC bias stress which include positive and negative bias stress on gate and drain of TFTs. What's more, we discuss asynchronous gate and drain bias stress on TFTs, and study the degradation mechanisms.
