The device was tested by using GSK-166 vibration table and compared with standard sensor AC43 through the metrological verification, and the?results showed that the performance parameters of the device?meet the requirements of earthquake early warning system basically.Key Words: MEMS technology, earthquake early warning, vibration picking device1 Introduction Physics of the earth is a science based on observation and measurement, seismology has a rapid development since the instrument have emerged and the method based on the instrument observation was established. After the development of several generations, seismometer have developed from the record by magnifying smoke using initial mechanical lever to measurement Integrated electronic technology and computer technology, improved the frequency band range and detecting precision substantially, and it make the seismological research and development enter a new stage. With the research and development to seismology science and requirement of space detection to the moon and the mars, combining with development of the modern electronic and computer technology, modern seismic sensors need to develop towards low power consumption, miniaturization, chip, low cost and high reliability, and be able to get full band observation and measurement. Modern measurement instrument based on mechanical hammer have some advantages such as high low resolution, large dynamic range, but show the deficiencies in the application. Micro
