This paper is concerned with a physical model of an interdigitated sensor working in a frequency range from 100 Hz to 10 MHz. A theoretical approach is proposed to optimize the use of the sensor for bioimpedance spectroscopy. The correlation between design parameters and frequency behavior in coplanar impedance sensors are described. CoventorWare  software was used to model the biological medium loaded interdigital sensor in three dimensions to measure its electrical impedance. Complete system simulation by a finite element method (FEM) was used for sensor sensitivity optimization. The influence of geometrical parameters (number of fingers, width of the electrodes) on the impedance spectroscopy of the biological medium was studied. The simulation results are in agreement with the theoretical equations of optimization. Thus, it is possible to design a priori such sensor by taking into account the biological medium of interest that will load the sensor.

“…We want to measure the elongation of a specific protrusion on the scatterer. Our numerical experiment does not use actual field measurements; rather, the amplitude of the scattered electric far field is calculated using the COMSOL software [3,9]. The library entries are samples of the magnitude of the scattered electric far field, taken over the angle of 30 • symmetrically with respect to the x-axis.…”

The main idea of this article is taking advantage of heat energy accumulation in building walls in order to design more effective heating system. Essential article goal is to simulate thermal construction responses in dependence on changing boundary conditions. Model geometry has been developed in virtual design studio CATIA and implemented in numerical simulation software COMSOL Multiphysics, with the intention to predict environmental temperature precisely. A threedimensional finite element model of laboratory was developed with the aim of achieving detail energy transfer in the real buildings during the transient process in the walls and internal air. On the contrary, many articles utilizing water or wax energy storage to decrease heating/cooling costs this work is focused on future optimization of control strategy based on heat accumulation in walls without requirement of any additional material. In this paper simulated temperature development is analyzed in the building which is consequently verified by experimentally measured temperature data.
