For a plate-type capacitor, C = εA/d, three parameters ε, d, and A can be used to tune the capacitance, C, of a capacitive sensor. For our iontronic sensors, ε represents the permittivity of the
Figure 7. A diagram showing a typical 45° crack. The red electrodes are where the crack has passed through the active stack. This represents a risk for a short circuit. Q5. What are some common ways that flex cracking occurs? Any activity that subjects the PCB to significant bending after the MLCCs have been soldered on the board risks cracking.
Interdigital capacitors are fundamental components in RF and microwave circuits, known for their ability to provide high capacitance values in a compact size.

typically extend parallel to the electrodes. 1.3. Delaminations and knit line defects were a rather common defects in early ceramic capacitors, but are rare in contemporary MLCCs, especially those manufactured to military specification. Formation of the electrode-ceramic delaminations during manufacturing can be attributed to variety of reasons. C.

In general, capacitive pressure sensors consist of two electrode layers with a dielectric layer sandwiched between them. 9,10 When pressure is applied to these electrode layers, this causes the sensor to deform, 14–16 changing the distance between the two and affecting the capacitance value. The composition of the dielectric will also greatly affect the …
