The pyroelectric phenomena expressed in formulas

W. Thomson tried to establish formulas of the pyroelectric phenomena after he predicted a reverse pyroelectric effect phenomenon in "On the thermal effects of fluids in motion" (8) but his theory was not complete because the amount of electric charge was not included as a parameter in related formulas.

Riecke introduced electronic charge related formulas and successfully expressed the pyroelectric phenomena in formulas (9) in 1885.

(8) Thomson,W.,Math.Phys.Papers l ,p.316
(9) Riecke,E.,1885,Nachr.Ges.d.Wiss.Gott.,ss405-440

[Please note]
There is sparse information about research history of the pyroelectricity/piezoelectricity effects caused by tourmaline. We refer to and quote from this literature as the events are presented in chronological order.
