Capacitive Sensor Operation and Optimization | Lion Precision

Capacitive sensors are most often used to measure the change in position of a conductive target. But capacitive sensors can be effective in measuring presence, density, thickness, and location of non-conductors as well. Non-conductive materials like plastic have a different dielectric constant than air. The dielectric constant determines how a ...

Proximity sensors: Types and applications

The capacitive proximity sensors have circuits same as that of inductive sensors, but the electromagnetic coil is replaced by a metal electrodes. The electrode in the sensor acts as one plate of the capacitor while the target acts as the other plate of the capacitor. The air gap between the two functions as the dielectric. When the target enters the sensing range and the target changes the ...

Capacitive sensing - Wikipedia

Capacitive sensors are constructed from many different media, such as copper, indium tin oxide (ITO) and printed ink. Copper capacitive sensors can be implemented on standard FR4 PCBs as well as on flexible material. ITO allows the capacitive sensor to be up to 90% transparent (for one layer solutions, such as touch phone screens). Size and spacing of the capacitive sensor are both very ...
