Nano supercapacitors and the effect of pyroelectricity or the effect of electric pressure
Researcher and author: Dr. ( Afshin Rashid)
Note: In nano-supercapacitors, pyroelectricity is a phenomenon that produces electricity when heat is applied to a material. This phenomenon is different from the thermoelectric phenomenon in ( nano-supercapacitors). The temperature change changes the atomic position in the structure. The crystal changes slightly, in a way that the polar state of the dielectric material ( nano supercapacitors) changes. This polarity change increases the voltage in( nano supercapacitors) .
In nano supercapacitors, pyroelectricity provides one of the best performance principles for detecting temperature changes. This occurs in the polar material and leads to the appearance of surface charges proportional to the temperature change in nanosupercapacitors . The main structure of a nano supercapacitor is a planar one,on whichof pyroelectricity In nano-supercapacitors, the following electricity from a permanent electric dipole moment of the unit cell of the crystalline structure or, in macroscopic terms, from an intrinsic ("spontaneous") electric polarization. This polarization in nano-supercapacitors changes with heating and cooling, resulting in electric charges on the surfaces. Nano capacitors are created in a special way.
In a nanosupercapacitor , spontaneous polarization can exist only along a polar direction that has no equivalent symmetric direction. ( In nano supercapacitors, the condition for the occurrence of the effect of electromagnetism or the effect of electric pressure) is expressed uniquely.
In its internal structure, the nano supercapacitor has a polarization effect of pyroelectricity or the effect of electric pressure. If the direction of spontaneous polarization can be reversed by an electric field ("switch") and lead to the reverse behavior of the current in the nanosupercapacitors will be Nano-supercapacitors need to use nano-electrolyte packages to insulate the internal elements of the nano-supercapacitor from thermal disturbances and electromagnetic noise and make it difficult to miniaturize them.
In modern pyroelectric detectors, nano-supercapacitors are widely used for various applications because they are simple, robust and offer good performance. In nano-supercapacitors,pyroelectric detectors are formed as thin-plate capacitor bipolar elements that change the charge density in the electrodes when exposed to heat. The microphonic effect (vibrations) that cause the piezoelectric response in nano-supercapacitors should be minimized.

This phenomenon is different from the thermoelectric phenomenon in ( nano-supercapacitors). The temperature change changes the atomic position in the crystal structure. changes, in such a way that the polarity of the dielectric material ( nano supercapacitors) changes.
