Thanks to embroidery, which has been recognized as one of the most promising manufacturing techniques for integrating antennas into clothing, the antennas are more robust, more flexible, fully washable and comfortable for...
source: RICE, FEE, University of West Bohemia in Pilsen, EPCI e-Symposium Abstract: Wearable electronics and smart textiles is rapidly developing area currently. An integration of electronic components and systems directly on/into textile substrates leads to the development of promising new technologies among which it is possible to include printing of passive electronic components and/or embroidering of passive electronic components directly onto textile substrates using...
source: Heraeus, EPCI e-Symposium Abstract: The major use of polymer aluminum and tantalum capacitors is for low voltage consumer electronics. The development of conductive polymer dispersions has extended the voltage range of polymer capacitors up to 125 V in the last years and opened the door for high reliability applications like automotive. We present the next generation of polymer aluminum capacitors reaching rated voltage...
source: RICE, FEE University of West Bohemia, EPCI e-Symposium Abstract: Aerosol Jet is a selective direct writing deposition technology. It generates aerosol from an inserted ink and aerodynamically focuses this aerosol in a print head. This allows the aerosol beam to be focused to the distance (between the tip of the deposition nozzle and a substrate) up to 15 mm. Thanks to that, the...
source: Brno University of Technology CEITEC, EPCI e-Symposium Abstract: Degradation of supercapacitor (SC) is analyzed by accelerated aging test. Evolution of SC parameters is determined before the aging test, and during up to 8 x 105 cycles of both 75% and 100% energy cycling. Capacitance fading, equivalent series resistance (ESR) increase, and leakage current trend are analyzed for off-the-shelf CapXX SC. Presented model...
