Abstract


The electrochemical impedance spectroscopy is a transient electrochemical technology , is a very important research method of electrochemical measurement techniques . In recent years , the impedance method has a growing number of applications in the electrode reaction mechanism , electrodeposition , corrosion and chemical power research . Meanwhile, with the continuous development of electronic technology , electrochemical workstation has increasingly become one of the commonly used equipment in chemical research , AC impedance spectroscopy measurements also increasingly become the electrochemical workstation necessary to provide one of the functions . The Western countries AC impedance spectroscopy measurement instrument research carried out earlier , the results are relatively abundant , has developed the highest sweep frequency up to 8MHz instrument . Domestic level is relatively backward , level sweep range of the highest frequency 115KHz look , therefore , the development of a sweep range to 1MHz impedance spectroscopy measurement instruments , for narrowing the gap with foreign countries , while providing a moderate sweep range , cheap the instrument used for domestic chemical research areas of great significance . This article briefly describes the theory and design of electrochemical impedance spectroscopy method of measuring the phase difference - digital correlation method . Hardware design , digital signal generator uses a combination of MCU and FPGA technology , using high - performance operational amplifier to build a potentiostat . Data acquisition , low bias current , high input impedance voltage follower used to reduce the negative impact of the test system , the hardware synchronous dual-channel sampling and automatically go to the DC bias amplifier technology greatly improves the signal-to-noise ratio , large used to make the system of the capacity of RAM can store more data collection , thereby increasing the integration time, and improve the measurement accuracy . Lower machine plays a master role MCU MCU is responsible for receiving and interpret instructions from the PC software . Software , lower machine FPGA and MCU programming ideas . PC application software is based on Windows XP development , it is easy to use , powerful, can graphically displayed in real time measurement results , of course, is not this article focuses . The article also describes some instrument commissioning and testing situation , and some of the problems currently exist to do some research into some outlook on its future development .
