A Review on Applications of Capacitive Displacement Sensing for Capacitive …
Capacitive proximity sensors (CPSs) are ubiquitous because of their simple design, low cost and low consumption. Capacitive displacement sensing, as one of the three sensing modalities, works for long distance and can be unitized to measure more physical quantities compared with capacitive volume and deformation sensing. In this …

Displacement Current
So, the displacement current equation tells us that the displacement current is proportional to how quickly the electric field is changing in the capacitor. When the electric field changes rapidly, the displacement current is large; when it changes slowly or not at all, the displacement current is small or zero.
