ABSTRACT
In the third edition of the Biomedical Engineering Handbook (Physiology of Thermal Signals), also republished in this edition, we introduced the reader to skin thermal properties in response to stress, regulation of skin blood flow for heat transfers, modeling equations, and objective thermography [1]. The objective thermography explored the efficiency of heat transport in the hand-reduced blood flow, nerve block and laser Doppler mapping, and sports medicine injury applications. Most of the work in this current publication on thermal signals builds on that foundation of information. However, before we go into further detail on the use of IR thermography, it is important to review some basic principles in thermal physiology.
