Regulated Ion‐Diffusion Hydrogels for Subtle and Multimodal Temperature‐Strain Sensing in Wound Monitoring

Advanced Functional Materials, EarlyView.
A soft, dual‐channel hydrogel patch enables simultaneous detection of wound temperature and strain by integrating ion‐diffusion‐mediated thermoelectric and resistive sensing. The conformal design maintains stable performance during motion, capturing subtle inflammatory and mechanical changes for continuous wound monitoring.

Effect of Heat Transfer on the Performance of Thermoelectric Heat Pumps

Journal of Non-Equilibrium Thermodynamics, 2001
AbstractThe performance analysis of thermoelectric (semiconductor) heat pumps is performedusing the combined method of finite time thermodynamics and non-equilibriumthermodynamics. The heating load and coefficient of performance (COP) expressionsfor the heat pump, which is composed of multi-elements, are derived with con-siderations of heat transfer ...

Augmenting the Condenser Heat-Transfer Performance of Rotating Heat Pipes

AIAA Journal, 1978
A rotating heat pipe assembly was tested at rotational speeds of 700, 1400, and 2800 rpm using distilled water as the working fluid. Tests were made during film condensation on several copper condensers, including smoothwalled cylinders, an internally finned cylinder, and a truncated cone.

The performance of a thermoelectric heat pump with surface heat transfer

Solid-State Electronics, 1963
Abstract The differential equations which describe the steady state temperature distribution in a thermoelement with constant properties and with convective heat transfer from its longitudinal surface are presented and solved analytically. The solutions are applied to a single-element thermoelectric heat pump to determine the effect of surface heat ...

Study on Heat Transfer Performance of Skin Heat Exchanger

Experimental Heat Transfer, 2014
Cooling technology is facing new challenges with the increase of electronic equipment power onboard aircraft. The traditional heat sink based on high-altitude bleed air does not satisfy this increase of cooling demands. In this article, an air/air-type skin heat exchanger is studied for cooling aircraft electronic equipment.

Heat Transfer Performance of Radiator Heating System with Alternative Heat Transfer Fluids

2020
Heat transfer fluids (HTFs) are an essential heat transport medium in many wet heating and cooling systems. They carry Heat from the generation source to the place where it is being used. Therefore, HTFs should have the capability of carrying Heat efficiently. The ability of HTFs to carry out the maximum amount of Heat with minimum loss is dependent on

Influence of Irreversible Heat Transfer on Heat Engine-Driven Heat Pump Performance

Thermodynamics and the Design, Analysis, and Improvement of Energy Systems, 1995
Abstract The coupling of a heat engine with a conventional compression heat pump is considered. Classical thermodynamics would provide, as upper performance limit of such a system, the one achieved in the case in which Prime Mover and Heat Pump both operate according to a Carnot cycle. Finite-time thermodynamics, utilizing
