Thermal modeling of planar and cylindrical biomedical multilayers structures in frequency domain

Strąkowska Maria, Więcek Bogusław

Measurement Automation Monitoring

2019

Vol. 65, No. 2

32--36

Planar and cylindrical thermal models of biomedical multilayer structures with perfusion are presented in this paper. For each layer the models are solved analytically in frequency domain using the Laplace transform. Modeling the multilayer structure allows formulating the set of linear equations with unknown integral constants. As a result, the thermal impedance Zth(jω) is calculated. Next, the poles of thermal impedance are estimated using Vector Fitting (VF) method. Finally, distribution of thermal time constants allows evaluating the temperature response T(t) of the modeled structure.

Low-cost IR system for thermal characterization of electronic devices

Kopeć M., Więcek B.

Measurement Automation Monitoring

2018

Vol. 64, No. 4

103--107

In this article, a Low-cost measurement Infra-Red (IR) system for dynamic thermal testing of electronic devices is described. The element is powered by a step-function current and simultaneously temperature is measured by a fast single-detector IR head. The thermal impedance Zth(jω) is calculated using the Laplace transform and the Foster network is to get thermal time constants distribution.
