Kinetics of Moisture Sorption and Reverse Bias Degradation in Chip Tantalum Capacitors

source: ASRC Federal Space and Defense (NASA), EPCI e-Symposium Abstract: Exposure of chip MnO2 tantalum capacitors to humid environments might result in increased ESR, leakage currents, and first turn-on failures.  However, there is a lack of literature data on the effect of moisture on reverse bias behavior of the parts. The presence of moisture can also result in pop-corning when a high water vapor...

Energy Harvesting is not Fiction Anymore

source: Würth Elektronik eiSos GmbH, EPCI e-Symposium Abstract: Our environment is changing and everything is becoming “electronified”. Our glasses, our hand gloves, shirts, shoes etc., can be connected already today with our smartphones and can send commands to the machinery surrounding us. We want this comfort, and we are all looking forward to having Smart Homes.   Chip manufacturers have introduced a new generation...

Capacitors and Resistors with Extended Operating Temperature Range for GaN Applications– Development and Space Evaluation

source: Alter Technology, ESA ESTEC, EPCI e-Symposium Abstract: During the last decade, a growing number of applications demanding higher power electrical consumption have emerged in some industrial sectors such as in the military, automotive or space ones. Consequently, electrical components with higher temperature range and rating voltage operation are needed. In addition, the good thermal characteristics of Silicon Carbide (SiC) and Gallium Nitride (GaN)...

Carbon Nanotubes Ammonia Sensor Printed by Aerosol Jet System

source: RICE, FEE, University of West Bohemia in Pilsen, EPCI e-Symposium Abstract: This article deals with ammonia gas sensor based on carbon nanotubes. Active layer is deposited on a flexible substrate by new deposition technique called Aerosol Jet. The deposition technique remove deficiency of today’s common used deposition technique, where it is very difficult to deposit a thin homogeneous layer of carbon nanotubes. The...

Embroidered textile antennas based on hybrid sewing thread

source: RICE, FEE, University of West Bohemia in Pilsen, EPCI e-Symposium Abstract: This paper presents a research focused on textile antennas which are made embroidered from a novel hybrid conductive sewing thread. 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...
