One very important parameter of a supercapacitor is the Equivalent Series Resistance (ESR). The energy that can be stored in a supercapacitor depends on ESR, so we intend to measure that parameter. Our tests were made on a 350F supercapacitor, 14V, produced by Econd Ltd. We have two methods: the first consist in evaluating ESR by constant current discharge, and the second method consists in a dynamic discharge cycle at a constant current. After measurements and some mathematical evaluations a real value of ESR is proposed.","PeriodicalId":337429,"journal":{"name":"2009 32nd International Spring Seminar on Electronics Technology","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115011492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Heat pipe is an equipment which allows a very effective heat transport. They are commonly used in electronic devices and in many other types of equipment as well. Some applications require heat flow controllability. For that purpose heat pipes are modified to many different constructions with variable heat conductance. Magnetic field control of heat transport is a new solution researched in a few laboratories in the world and still not practically applicated. According to the results of some experiments, implemented in our laboratory and several another laboratories, it seems to be possible to control heat transport in chosen types of heat pipes by a static magnetic field. The cryogenic heat pipe filled with pure oxygen has been made for that purpose and a testing device has been arranged as well. We have found out that the heat transport efficiency of the heat pipe has rapidly decreased by a magnetic field exposure. Some interesting results of our experiments will be presented in this paper.","PeriodicalId":337429,"journal":{"name":"2009 32nd International Spring Seminar on Electronics Technology","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129471095","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To get results of the experiment the test boards were stresses using the thermal cyclic method in range from 0 °C to +100 °C, with the dwell time of 15 minutes at the maximum temperature. Before the test itself the boards were aged at increased temperature according to the standard of IPC-SM-785.

The results of modeling were tested for model structures of RTDs with barrier layers formed of AlxGa1−xAs and AlxGa1−xN. The model is free of numerical instabilities and adequately expresses the main tendencies in the dependencies of I–V characteristics' parameters on the topology.

These properties were utilized by the authors in new type of polymer thick film composition. Polymer compositions filled with carbon nanotubes are topic of interest in fabrication of new type printed electronics circuits, dedicated for production of elastic displays, transparent electrodes, EM shields, and various types of sensors such as pressure, temperature or biochemical sensors. Investigated materials were poly(methyl methacrylate) filled with multiwalled carbon nanotubes. Several polymer compositions were prepared with different concentration of polymer in solvent. Different amount of carbon nanotubes were added to each resin. Compositions were homogenized, screen printed on polyester substrate and cured. Resistance changes in function of polymer concentration were elaborated. Different concentration of polymer in solvent has significant influence on film thickness. As the result, fabricated thick film electrodes have less polymer concentration. In such composites more nanotube interconnections are present and more conductive paths are created.","PeriodicalId":337429,"journal":{"name":"2009 32nd International Spring Seminar on Electronics Technology","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133145307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
