In this thesis, I present techniques to image temperature fields in two important engineering systems - 3D integrated circuits (3D ICs) and electrochemical energy storage devices – and in fluids which are of importance in both engineering and biology. In 3D ICs, I demonstrate how x-ray diffraction intensities can be used to simultaneously map temperature in different device layers. In electrochemical energy storage devices, namely proton exchange membrane (PEM) fuel cells and solid-state Li ion batteries, I discuss how magnetic resonance imaging (MRI) can be used for thermometry of the electrolyte layer and demonstrate the mapping of temperature and hydration in PEMs. In fluids, I demonstrate how the sensitivity of MR thermometry can be enhanced with the immersion of nanoparticles. For all these systems, I discuss the spatial, temporal and temperature resolution achieved with the demonstrated techniques and the potential ways to improve them. Finally, I discuss the applicability of electron paramagnetic resonance (EPR) imaging of n-type semiconductors for possible 3D thermometry in engineering and biology.
