6 FAQs about [Capacitor Current Detector Image]

How does a capacitance sensor work?

Capacitance sensors can nondestructively measure the capacitance between a sensor and a target. By measuring the capacitance, it is possible to detect the presence or absence of an object near the sensor and the distance between the object and the sensor.

Why do we use a capacitance image sensor?

Therefore, using a capacitance image sensor made it easier to visualize the electrical connections. In Figure 19, transparent electrodes with a pitch of 216 µm were lined up, and the electrode to which φC was applied appeared white.

What is a composite capacitance C sensor?

As shown in Figure 12 a, C S could be seen as a composite capacitance C sensor from the detection electrode to the chip surface, which was calculated from the passivation film thickness, and capacitance C ext. from the chip surface to the object.

What is a proximity capacitance image sensor?

It is used in noncontact switches, level sensors, continuous cell density measurement devices [ 4 ], and pressure sensors [ 5 ].
