Semi-numeric Boundary Element Method for Piezoelectric Fluid Sensors Using a Fourier Spectral Approach
Sprache des Vortragstitels:
Abstract?A semi-numeric boundary element-based
method for fluidic piezoelectric disc sensors excited
by lateral and transversal electric fields is presented.
Besides AT-cut quartz, the method is also applied
to alternative materials like lithium niobate, lithium
tantalate and langatate which show much stronger
coupling factors for lateral field excitation. Additionally
to viscosity and density, the electrical conductivity and
permittivity and the thickness of the fluid layer are
considered. Their significant influence on the type of
excited mode is discussed.
