## Additional information
|
|
|
|
|
|
This is a 3D, multiphysics
|
|
|
model of a MEMS magnetometer, coupling electromagnetic (electrokinetic),
|
|
|
mechanichal (elastic) and thermal models. To run the model, open
|
|
|
`magnetometer.pro` with Gmsh.
|
|
|
|
|
|
When an alternating current flows through it, the magnetometer starts to vibrate
|
|
|
if it is placed in a magnetic field. The amplitude of the vibration can be used
|
|
|
to measure the magnetic field. To increase sensitivity, the frequency of the
|
|
|
current is tuned to excite a resonant mode of the xylophone-type
|
|
|
structure. Several analyses are predefined: uncoupled modal analysis of the
|
|
|
structure (`Eigenmodes`) and calculation of the current flow
|
|
|
(`Electrokinetics`), static and dynamic electro-mechanical analysis
|
|
|
(`Electro-mechanical`), and coupled electro-thermal analysis
|
|
|
(`Electro-thermal`).
