“…In the past few years, thermogalvanic hydrogels have made significant advances in both thermoelectric conversion and thermoelectric sensing [ 138 , 139 , 140 , 141 ]. Compared with other energy devices, such as chemical batteries, supercapacitors, and solar cells, first of all, thermogalvanic hydrogels can directly convert heat into electricity, enabling the recovery and utilization of applied waste heat, thus contributing to the development of green energy.…”

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.

“…Readers accustomed to TET in the form of the Gibbs Fundamental Form which is applicable to the thermodynamics of simple fluids (i.e., dE = TdS -pdV [35,49]), will have noticed that our EQH, which we have abbreviated by C, is the entropy of Clausius's and Gibbs's thermodynamics. In actuality, however, it is much more than that: using our EQH as entropy, we can formulate models and theories that go beyond TET, such as a full-fledged thermodynamics of Uniform Dynamical Systems [2], Continuum Thermodynamics [26][27][28], and applications to irreversible thermodynamics such as those found in thermoelectricity [52,[159][160][161] (see also Section 5).…”

We discuss how to construct a direct and experientially natural path to entropy as a extensive quantity of a macroscopic theory of thermal systems and processes. The scientific aspects of this approach are based upon continuum thermodynamics. We ask what the roots of an experientially natural approach might be—to this end we investigate and describe in some detail (a) how humans experience and conceptualize an extensive thermal quantity (i.e., an amount of heat), and (b) how this concept evolved during the early development of the science of thermal phenomena (beginning with the Experimenters of the Accademia del Cimento and ending with Sadi Carnot). We show that a direct approach to entropy, as the extensive quantity of models of thermal systems and processes, is possible and how it can be applied to the teaching of thermodynamics for various audiences.

“…84 It was found in one of the studies 85 that TEM with a height of 1.1 mm provides maximal output power as compared with some commercial devices with a height of 1.5 mm. A recent study by Wolf et al 86 also conducted cross-sectional area optimization of three types of TEM for maximum power efficiency using the Finite Element Method (FEM). Using circulating fluid, 87 heat pipe, 88 passive techniques, 89 or application of PCM 90,91 to maintain temperature gradient between the two sides of TEM is also used for enhancement of efficiency of operation.…”

Thermoelectric module (TEM) is a scalable, reliable, and noise-free solid-state device that converts thermal energy into electrical energy and vice-versa. TEM has been explored for cogeneration, electronics cooling, power production, waste heat harnessing, and air-conditioning. The potential applications of TEM-based systems are in the building, for heating, ventilation, and airconditioning (HVAC), which represents its significant share in the energy consumption in the building sector. A photovoltaic powered thermoelectric system has even a stronger techno-economical potential. The main objective of the study is to explore the potential of PV-powered thermoelectric technology as a distributed air-conditioning system in buildings. In this study, a comprehensive review on PV-powered thermoelectric technology is presented in addition to several new design concepts for application in future development of sustainable zero energy building technologies in view of sustainability and global climate change concerns. A novel "STEM-Wall" concept is also discussed concerning future thermoelectric system designs for buildings. Additionally, the thermal comfort aspect of HVAC systems is critically analyzed by reviewing the standard predicted mean vote and predicted percentage of dissatisfied indices. The research outcome, analysis, and potential of TEM applications for future sustainability and thermal comfort in buildings are presented. Further follow-up research areas are also identified.
