Congratulation to Arjarn Nimit and his colleague!
It is a first step of MEMs in Thailand.
Please keep go on.

Help me regarding question 3,4 and 5
(Question)
The mechanical transfer function of an accelerometer relates the displacement of the mass (the output) to the applied acceleration (the input).
(i)Draw schematically the spring-mass-frame model of an accelerometer and illustrate the forces that act in this system when an external acceleration is applied.
(ii)Write the equation for the displacement of the mass under the applied forces.
(iii)What is the cross axis sensitivity of an accelerometer?
(iv)Consider that the applied acceleration is a sinusoidal function of time, producing vibrations of the mass. Illustrate schematically the amplitude of these vibrations as a function of the frequency (from zero to a frequency higher than the resonance frequency of the system).
(v)Illustrate the effect of the damping on this amplitude.
(vi)Illustrate schematically a capacitive surface micromachined accelerometer and explain its principle.
(vii)Name a few critical steps in the fabrication process of such an accelerometer
