Qualitative comparison of MEMS vibration sensors
 Hasík, Stanislav ; Havránek, Zdeněk (referee) ; Klusáček, Stanislav (advisor)
The aim of this bachelor thesis is a qualitative parameter validation of MEMS vibration sensors using calibration devices from the companies SPECTRA a Brüel & Kjr. First part of study deals with different types of MEMS vibration sensors on the piezoresistive, capacitive and thermal principle of operation. The study also deals with primary and secondary methods of calibration of vibration sensors and devices used for these calibration methods. The second part of the thesis is to use the calibration chains and secondary calibration methods to verify the sensitivity and temperature dependences of three particular MEMS accelerometers from the companies STMicroelectronic, MEMSIC and Panasonic. The measured characteristics are compared with catalog datasheets. In the end of the thesis are also discussed the possibility of the suppression these temperature effects.
