One group calculated that a pyroelectric in an Ericsson cycle could reach 50% of Carnot efficiency, [24] [25] while a different study found a material that could, in theory, reach 84-92% of Carnot efficiency [26] (these efficiency values are for the pyroelectric itself, ignoring losses from heating and cooling the substrate, other heat-transfer ...
The Olsen cycle can generate electricity directly from heat when applied to a pyroelectric material, [6] and has been the most favorable method for the generation of electricity from heat using pyroelectric energy harvesting. [7] It consists of two isothermal and two isoelectric field processes in the displacement versus electric field diagram. [8]
The phenomenon of pyroelectric fusion has been demonstrated using a lithium tantalate crystal producing a large enough charge to generate and accelerate a beam of deuterium nuclei into a deuterated target resulting in the production of a small flux of helium-3 and neutrons through nuclear fusion without extreme heat or pressure.
Photopyroelectric As known that Photopyroelectric can be regarded as –Photo +Pyroelectric，which means any optical systems using a pyroelectric detector or imaging system, In addition, pyroelectricity could be depicted as the capability of the components formulating the transient voltage when heated or cooled.
Ferroelectric polymers, such as polyvinylidene fluoride and poly[(vinylidenefluoride-co-trifluoroethylene], are very attractive for many applications because they exhibit good piezoelectric and pyroelectric responses and low acoustic impedance, which matches water and human skin. More importantly, they can be tailored to meet various requirements.
The novel idea with the pyroelectric approach to fusion is in its application of the pyroelectric effect to generate accelerating electric fields. This is done by heating the crystal from −34 °C to +7 °C over a period of a few minutes. Nuclear D-D fusion driven by pyroelectric crystals was proposed by Naranjo and Putterman in 2002. [8]
This new class of ferroelectric materials exhibit "spontelectric" properties, and may have wide-ranging applications in device and nano-technology and also influence the electrical nature of dust in the interstellar medium. Other ferroelectric materials used include triglycine sulfate, polyvinylidene fluoride (PVDF) and lithium tantalate. [27]
Materials Today is a monthly peer-reviewed scientific journal, website, and journal family. The parent journal was established in 1998 and covers all aspects of materials science . It is published by Elsevier and the editors-in-chief are Jun Lou ( Rice University ) and Gleb Yushin ( Georgia Institute of Technology ). [ 1 ]
