The principle of hemispherical resonator excitation and detection is shown in Figure 4, where the change in capacitance is converted into a voltage (V) by a test circuit, which in turn yields an angular velocity ω. When the hemispherical resonator of the gyroscope vibrates, the detection mode is excited by the Coriolis force, and the amplitude ...
Capacitors Basics
What are capacitors? In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other. The area between the conductors can be filled with either a vacuum or an insulating material called a dielectric.
Separation of mass and gap errors of hemispherical resonator …
Since the capacitive gap is far smaller than the thickness and the radius of the resonator, the capacitor can be equivalent to a parallel plate capacitor. The schematic is illustrated in Fig. 3, where the up-plate represents the resonator rim, the bottom-plate corresponds to the flat electrodes, and the gap between them is defined as d .

The principle of hemispherical resonator excitation and detection is shown in Figure 4, where the change in capacitance is converted into a voltage (V) by a test …
Microphones
Capacitor (condensor) microphones work on a different principle: one plate of a capacitor is accessible to the air while the other plate is fixed. The capacitor is charged by an applied voltage or by a permanent charge on one of the plates. As air pressure changes, it causes the distance between the plates to change, thus changing the capacitance.

There is also an equal capacitance from the inside surface and infinity. Since these two capacitors are in parallel, hemisphere A has a total capacitance of (r/2k + r/2k = ) r/k. The same applies to hemisphere B, which is a capacitor in parallel with hemisphere A, so the total capacitance of both hemispheres is ( r/k + r/k = ) 2r/k).
