Sorption heat storage is expected to play an important role in future thermal energy systems, particularly in buildings and industrial processes. For optimal operation, it is important to control the parameters of heat storage systems, such as the state-of-charge. In this study, we show the possibility to use compact and cost-effective micro-opto-electro-mechanical spectroscopic sensors for state-of-charge control of diverse sorption heat storage materials.
