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...
source: University “Politehnica” of Bucharest, EPCI e-Symposium Abstract: Current trends in supercapacitor technology (principially in lowering series discharge resistance) have promoted the devices into roles parallel to, or replacing traditional batteries. In cases where power consumption is low, supercapacitors are an attractive alternative, completely eliminating batteries and further offering higher surge currents. This opens the path towards powering mobile switching circuits, or with high-consumption...
source: Gdańsk University of Technology, EPCI e-Symposium Abstract: Low frequency noise is a well-known tool for quality and reliability assessment of electronic devices. This phenomenon is observed in different electrochemical devices as well (e.g., smart windows, electrochemical corrosion processes). Thus, we can assume that the same tool can be used to asses quality of supercapacitors. Their quality is usually determined only by capacitance and/or...
source: FEEC Brno University of Technology, EPCI e-Symposium Abstract: A new project with a budget of 262 thousands Euro was motivated by the lack of micromachined energy storage solutions that can be integrated with a MEMS harvester on a chip with a specific circuitry. These key components of the system are highly needed for autonomous microsystems and have to be integrated to enable an...
