Modeling heat transfer in humans for body heat harvesting and personal thermal management

Exploring Thermal Dynamics in Wound Healing: The Impact of Temperature and Microenvironment

“…14 The spectrum of biothermal transfer within the human organism is delineated through a confluence of conductive, convective, and radiative modalities, rendering the narrative of thermal energy conveyance notably complex. 15 Scholarly endeavors have been directed towards the elucidation of these complexities, yielding theoretical constructs and algebraic expressions that encapsulate the quintessential principles of biothermal transfer in biological matrices. This intellectual journey has led to the creation of analytical models that allow for a detailed examination of thermal phenomena.…”

A Hierarchically Nanofibrous Self-Cleaning Textile for Efficient Personal Thermal Management in Severe Hot and Cold Environments

“…Effective synergy of improved fabric thermal insulation and energy-free thermoregulation strategy is the key to tackle the above issues. , It is worth mentioning that an aerogel membrane with low thermal conductivity could reduce heat loss in low-temperature environments and block out heat input in high-temperature environments, making it an ideal candidate for thermal insulation in severe temperatures. − Cui et al reported an aligned porous structure fiber textile with low thermal conductivity inspired by the microstructure of polar bear hairs, which shows a good thermal insulation property in severely cold temperatures. Notably, the main way for the human body to dissipate heat is no longer radiative cooling but evaporative cooling in severely hot temperatures. , In our previous work, an asymmetrically wetting bilayer aerogel membrane textile with integrated - thermal insulation, evaporative heat dissipation, and radiative cooling have been proposed to increase heat dissipation in high temperatures . But it cannot achieve personal thermoregulation in severely hot and cold environments.…”

Noninvasive and Continuous Monitoring of the Core Body Temperature through the Quantitative Measurement of Blood Perfusion Rate

“…When CBT deviates from the normothermic temperature range (36.5−37.5 °C), a patient is considered to be in a state of hypo-or hyperthermia, which may endanger the health status of the patient. 6,7 Further progress may be prevented if such states are detected early. 8,9 Taylor et al 10 extensively discussed the relationship between CBT and illness and compared CBTs observed with the traditional invasive methods (esophageal, sublingual, tympanic, rectal, etc.…”

“…CBT of humans is defined as the temperature of the major internal organs, including the brain, liver, heart, and lungs, and the pulmonary arterial blood (blood that flows away from the heart to the lungs). − The measurement of CBT is crucial because it quantitatively indicates the degree of homeostasis. When CBT deviates from the normothermic temperature range (36.5–37.5 °C), a patient is considered to be in a state of hypo- or hyperthermia, which may endanger the health status of the patient. , Further progress may be prevented if such states are detected early. , Taylor et al extensively discussed the relationship between CBT and illness and compared CBTs observed with the traditional invasive methods (esophageal, sublingual, tympanic, rectal, etc. ), as illustrated in Figure b.…”
