In this paper, we present electro-thermal analysis and design of a combined MEMS micro hotplate and interdigitated-capacitance impedance sensor for gas sensing application using nano-porous materials like metal organic framework (MOF). The effects of design parameters of interdigitated electrodes such as width(W) and gap(G) of the capacitor, metallization ratio, number of electrodes and area of the capacitor. The influence of height of the electrode material, thickness of the insulation layer between the capacitance electrodes and the micro hotplate electrodes are studied. These design parameters are optimized to obtain a high bare capacitance of the electrodes using analytical and electric and thermal domain simulations in COMSOL 5. The design and thermal analysis of the micro hotplate for a temperature range of (150-300°C) and low power consumption is modelled and results are discussed.
