A kind of experimental platform for silicon MEMS (Micro-electromechanical Systems) acceleration sensor is constructed in order to solve the problem hard to be understood for MEMS acceleration sensor during teaching in classroom .This phenomenon happens because this kind of sensor has the character of little bulk (in micro meter) ,which results in the hardness to understand its working principle .It is mainly composed of an acceleration generating system ,a quartz beam accelerometer ,an MEMS accelerometer chip ,A/D converter circuit ,a single-chip microcomputer data collection unit and the LED display unit .Acceleration generating system is used to generate a series of acceleration signals .High precision quartz beam accelerometer acts as the standard evaluating device to the MEMS accelerometer chip .Experimental result indicates this system has excellent performance and fits the requirement of the experiment .Through the personal operation ,students’ practical abilities are greatly increased .Combination of experimental teaching and class teaching is greatly strengthened at the same time . This experimental system will offer great help to the courses of sensor technology and application ,and error theory and data processing .
