“…In terms of the stream function, which is correlated to v by the expression 6 = (-Jay, --/ax), we determine that We can significantly simplify the consideration if we compare the typical values of two terms in the right part of (22). In accordance with the results of reference [9], if the convective flow of liquid takes place under the influence of the temperature difference of 50 K, the arising difference of concentrations is 0.08M. Introducing /?…”

“…The principal steps of generalisation of that solution for the case of different electrode temperatures and two electroactive ions, and also the final formulas for the current-voltage dependency, are given in Appendix A. The main principle of the solution [14] is that instead of seeking the direct dependence j(U), the parametrical dependencies j(w) and U(w) should be in detail in a number of papers [7][8][9], is given in Fig. 3 (Curve a).…”

“…The other simplification is connected with the fact that in the main bulk volume of liquid the thermal flow density from one electrode to another is constant, that provides for the temperature profile remaining linear [9]. Some deviations from linearity are observed in the upper and lower parts of the cell, where the convective thermal transport becomes significant.…”

“…This prevents the systematic research of all possible variants of TGC. Actually, only a few calculations for some variants of TGC, more or less related to those real systems that already exist, have been made [9,10]. This is why it is necessary to work out a reasonably simple theoretical model which can help in studies of the principal properties of TGC and also provide a theoretical estimation of the efficiency of present TGC constructions.…”

Abstract-The functioning of thermogalvanic cells has been studied theoretically. The analysis for the simplest case which accounts for only diffusion transport of the reacting substances from one electrode to another has been made. The simple relation for thermodynamic efficiency of such energy sources was obtained. The diffusion-migration transport for the horizontally arranged cell and the diffusionconvection transport for the vertically arranged cell were studied in detail. The original mathematical methods for solving transport equations were used. Analytical results for the concentration distribution and the current-voltage curves were calculated. The principal role of electrode kinetics (fast changing of the equilibrium electrode potential with the temperature) was shown. Finally, the general algorithm for improving thermogalvanic cells was proposed.

Energy harvesters based on ferroelectric materials, which are capable of converting mechanical and thermal energies into electric power, have drawn unprecedented attention in both academic and industrial fields because of their great potential in harvesting human‐activity‐induced and other energies of the human body to drive low‐power, personal, portable, and implantable electronics. Based on previous works that uncovered the features of advanced materials and the nanotechnologies for the fabrication of ferroelectric generators, we emphasize the potential of ferroelectric energy harvesters in biomedical applications, with not only traditional ferroelectrics but also newly developed ferroelectric biomaterials. In addition, the latest representative integration schemes of hybrid generators with ferroelectric materials are outlined, which could markedly extend the functions of energy harvesters, especially for implantable and biomedical applications.
