A water capacitor is a device that uses water as its dielectric insulating medium. A capacitor is a device in which electrical energy is introduced and can be stored for a later time. A capacitor consists of two conductors separated by a non-conductive region. The non-conductive region is called the dielectric or electrical insulator.
The conductivity of water can change very quickly and is unpredictable if left open to atmosphere. Many variables such as temperature, pH levels, and salinity have been shown to alter conductivity in water. As a result, there are better alternatives to the water capacitor in the majority of applications.
The quality factor Q of an LC tank circuit describes the resonance behavior and represents the loss of the resonator. A higher Q-factor leading to a sharper resonance and longer detection distances is generally desirable for the sensor tag.
A capacitor is a device in which electrical energy is introduced and can be stored for a later time. A capacitor consists of two conductors separated by a non-conductive region. The non-conductive region is called the dielectric or electrical insulator. Examples of traditional dielectric media are air, paper, and certain semiconductors.
