Capacitive sensing. In electrical engineering, capacitive sensing (sometimes capacitance sensing) is a technology, based on capacitive coupling, that can detect and measure anything that is conductive or has a dielectric constant different from air. Many types of sensors use capacitive sensing, including sensors to detect and measure proximity ...
Evolutionary biology. Evolutionary capacitance is the storage and release of variation, just as electric capacitors store and release charge. Living systems are robust to mutations. This means that living systems accumulate genetic variation without the variation having a phenotypic effect. But when the system is disturbed (perhaps by stress ...
Quantum capacitance, [1] also known as chemical capacitance[2] and electrochemical capacitance , [3] was first theoretically introduced by Serge Luryi (1988), [1] and is defined as the variation of electrical charge with respect to the variation of electrochemical potential , i.e., . [3] In the simplest example, if you make a parallel-plate ...
Capacitance is the capacity of a material object or device to store electric charge. It is measured by the charge in response to a difference in electric potential, expressed as the ratio of those quantities. Commonly recognized are two closely related notions of capacitance: self capacitance and mutual capacitance.
Capacitive displacement sensors are "non-contact devices capable of high-resolution measurement of the position and/or change of position of any conductive target". [1] They are also able to measure the thickness or density of non-conductive materials. [2] Capacitive displacement sensors are used in a wide variety of applications including ...
Capacitance sensors (or Dielectric sensors) use capacitance to measure the dielectric permittivity of a surrounding medium. The configuration is like the neutron probe where an access tube made of PVC is installed in the soil; probes can also be modular (comb-like) and connected to a logger. The sensing head consists of an oscillator circuit ...
Quantum biology. Quantum biology is the study of applications of quantum mechanics and theoretical chemistry to aspects of biology that cannot be accurately described by the classical laws of physics. [1] An understanding of fundamental quantum interactions is important because they determine the properties of the next level of organization in ...
Chronoamperometry. Double-pulsed chronoamperometry waveform showing integrated region for charge determination. In electrochemistry, chronoamperometry is an analytical technique in which the electric potential of the working electrode is stepped and the resulting current from faradaic processes occurring at the electrode (caused by the ...
