This article proposes a non-conventional calorimeter for the power losses quantification of microelectronic devices during their operation. The system is based on the constant-volume calorimetry principle, mainly employed in bio-chemical applications. Additionally, this document presents a primary numerical study for proposed device. Several experiments were conducted to observe the heat transfer performance inside the system. Results were found useful for the eventual practical implementation.
