This book is a translation from a Russian book. In 2007, the authors created a new generation of layered composite-based sensors, whose advantages are high technology and thermal stability. The use of gradient heat flux sensors in laboratory and industrial conditions confirmed their reliability, showed high information, and allowed a number of priority results to be obtained. All of this is summarized in this book.

Heat Flux Measurement and Heat Flux Sensors.- Gradient Heat Flux Sensors.- Transient Heat Flux Measurement.- Multifunctional Performance of Gradient Heat Flux Sensors.- Testing of Gradient Heat Flux Sensors.- Gradient Heat Flux Measurement on Technical Objects.
