1. Capacitive displacement sensor 1

2. Capacitice displacement sensor 2

3. Capacitive displacement sensing 3

4. Electric dipoles 2
(3.10,3.11)

5. Near- and far field from dipole
Far field (dipole field) depend on:
Dipole moment (charge*separation)
Distance from dipole (->amplitude)
Angle with dipole (->direction)
Near field depend on:
Charge
Exact location of charges
Hyperphysics
Alonso/Finn: Fundamental univeristy physics

6. Dipoles in an electric field
Due to thermal agitation the alignment of the dipoles is proportional
to the applied field!!
Fraden p.47

7. Displaced charge
Total dielectric constant

8. Capacitive level measurement

9. Humiditiy sensor

10. Occupancy

11. Monopolar capacitive probe

12. Driven shield proximity sensor
