“…According to thermodynamic theory, the Se is given by:

where n is the number of electrons transferred, F is Faraday’s constant,

and

are the partial molar entropies of species A and B ,

and

are their Eastman entropies, and

is the transported entropy of the electrons in the external circuit [ 48 , 49 , 50 , 51 ]. Eastman transport entropy is explained by the interaction of the ion and its solvated shell layer with the solution.…”

Thermoelectric cells (TEC) directly convert heat into electricity via the Seebeck effect. Known as one TEC, thermogalvanic hydrogels are promising for harvesting low-grade thermal energy for sustainable energy production. In recent years, research on thermogalvanic hydrogels has increased dramatically due to their capacity to continuously convert heat into electricity with or without consuming the material. Until recently, the commercial viability of thermogalvanic hydrogels was limited by their low power output and the difficulty of packaging. In this review, we summarize the advances in electrode materials, redox pairs, polymer network integration approaches, and applications of thermogalvanic hydrogels. Then, we highlight the key challenges, that is, low-cost preparation, high thermoelectric power, long-time stable operation of thermogalvanic hydrogels, and broader applications in heat harvesting and thermoelectric sensing.
