In this paper an idea of wireless energy transfer using resonant inductors is presented. Comsol Multiphysics is used in order to simulate the energy transfer depending of the geometry of the resonant coil, parasitic components and position of the coils. Using different positions of the emitter coil and more than 1 resonant coil we can analyze the best case for transferring energy to the receptor.
This paper deals with the usage of the computer simulation for the mechanical testing of the PCB's to obtain optimal configuration for mechanical reliability. The main target is to determine factors that are the most important role for this kind of analysis. For this purpose sensitive analysis were made and following critical data were defined. The critical step is to determinate correct material...
Radio Frequency Identification (RFID) is the technology that is used in the daily life. A RFID system consists of RFID tags and readers including many electronic passive and active components. This article deals with design of chipless RFID tags that are screen printed on flexible substrates and do not need any electronic components for their function. There are also presented chipless RFID tag fundamentals...
This paper offers new results of material characterization of ferrite LTCC (Low Temperature Co-fired Ceramic) tape and deals with determination of its magnetic properties. Affects of processing parameters variation (firing profile) on properties of ferrite LTCC tape are determined for the commercially available ESL40011 tape. Obtained results provide information for complex permeability values for...
The objective of this research is to study various coil designs and to propose the pattern that can improve the performance of the pressure sensor. Wireless pressure sensor, based on polyimide foil, is designed, fabricated and tested. The proposed sensor is realised in heterogonous integration process and consists of PCB (Printed Circuit Board) coil, spacer and polyimide membrane with attached LTCC...
