Abstract. The paper presents an initial study and basic research of the state of the art systems and solutions for the simulation of the thermoregulatory sweating conditions. The simulation of the thermoregulatory sweating conditions has been treated by many researchers, and has become over the years a major area of interest for many industries (e.g. textile, protective garments, aeronautics, automotive industries and sports). The objective of this paper is to reflect and analyse the existing literature, for this purpose. Three existing systems and two thermoregulatory models will be characterized and critically discussed. The findings support the methodology for future applied scientific research (PhD thesis), which will use existing scientific knowledge to develop a practical application using suitable technology.

“…If 1 (clo) = 0.155 (m 2 KW −1 ) and if r cl /(ρ•c p ) = 1 (clo), then r cl = 1.2 (kgm −3 )•1004 (Jkg −1 K −1 )•0.155 (m 2 KW −1 ) = 186.74 (sm −1 ). The human body is represented as single segment using a onenode model (Katić et al 2016). According to Weyand et al (2010) M can be expressed as follows:…”

The Carpathian Basin climate in the time period 1971-2000 is analyzed in terms of the results obtained by the Köppen method and a clothing resistance scheme. A clothing resistance scheme is based on human body energy balance considerations taking into account human interperson variations as simply as possible. Interperson variations are considered by estimating human body somatotypes using the Heath-Carter somatotype classification method. Non-sweating, walking humans in outdoor conditions are treated. Environmental and human data are taken from the CarpatClim dataset and a Hungarian human dataset, respectively. Though the biophysical bases of the methods are completely different, the spatial structure of thermal climates expressed in terms of Köppen climate types and the clothing resistance parameter r cl are basically similar. A clothing resistance scheme creates more information than the Köppen method not only in mountain, plateau areas but also in lowlands. It is shown that more human thermal climate categories can refer to one Köppen climate formula irrespective of which Köppen formulae are considered. The magnitude and area heterogeneity of r cl is strongly sensitive to human somatotype changes. A clothing resistance scheme cannot be used in classroom applications; it needs to be drastically simplified while maintaining its sensitivity to somatotype changes in order to be competitive with the Köppen method.

“…The human body has an intricate built-in system to regulate its temperature to maintain a balance between metabolic heat production and heat loss to the environment. This balance between heat production and loss is important in maintaining a constant core temperature of the human body [78]. This thermoregulatory system is divided further into two parts consisting of active and passive systems [79,80].…”

“…This simplification allows for a quick analysis of the human thermal system. The multi-node model is more complicated as it represents the human body as cylinders subdivided into usually the core, muscle, fat, and skin layers [78].…”

Energy harvesting using thermoelectricity for IoT (Internet of Things) and E-skin sensors

et al. 2019

With the increasing demand for Internet of Things (IoT) with integrated wireless sensor networks (WSNs), sustainable power supply and management have become important issues to be addressed. Thermal energy in forms of waste heat or metabolic heat is a promising source for reliably supplying power to electronic devices; for instance, thermoelectric power generators are widely being researched as they are able to convert thermal energy into electricity. This paper specifically looks over the application of thermoelectricity as a sustainable power source for IoT including WSNs. Also, we discuss a few thermoelectric systems capable of operating electronic skin (e-skin) sensors despite their low output power from body heat. For a more accurate analysis on body heat harvesting, models of the human thermoregulatory system have been investigated. In addition, some clever designs of heat sinks that can be integrated with thermoelectric systems have also been introduced. For their power management, the integration with a DC-DC converter is addressed to boost its low output voltage to a more usable level.
