The Investigation of a Tin OxideBased MEMS Sensor for ...

In this thesis, the MEMS device is described together with its supporting equipment. Tests, and calibrations were performed and evaluations made on the MEMS sensor, and are discussed in three parts: laboratory calibration and evaluation, offengine installation and perfonnance, and onengine installation and performance. The MEMS device was first tested in a laboratory environment where the ...


MEMSbased electrochemical gas sensors and waferlevel methods

sensor [4], resonator [5] etc. MEMS based actuators such as micromirrors emerged some years later [6]. Recently, functional microstructures have gained importance with devices such as microneedles for painless drug delivery [7] and as microchannels for LabonChip applications [8]. The success of MEMS technology has given rise to several new

Sensing and control of MEMES Accelerometers

This thesis will focus on MEMS capacitive accelerometer which has two fundamental problems: sensing and control. MEMS technology gives possibility to integrate complex systems into a small single chip with low cost and multiple functions. However, the miniaturized devices also reduce the signal to noise ratio (SNR) and the dynamic range (DR), and also increase the system uncertainties during ...


MEMS graphene strain sensor

In this thesis, a Graphenebased MEMS pressure and strain sensor fabricated and patterned using a standard lithography process will be first presented as background information. The graphene strain sensor was transferred onto a thin, flexible plastic substrate after patterning.
