This paper provides an overview of Acoustic Energy Harvesting using the technology of Piezo-Electricity as well as the components of an acoustic energy harvester. It also demonstrates work done to study acoustic energy harvesting using a cylindrical Piezo-element made of Penta-Zirconate Titanate, PZT-5A. The work presented here aims at defining the electrical properties of the cylinder by measuring its impedance properties using a Precision Impedance Analyzer. The cylinder was found to have a capacitive effect over the audible frequency range. The obtained impedance values shall help match the impedance of the cylinder, the electric energy source, to the impedance of the load circuit that will make use of the harvested energy.","PeriodicalId":142369,"journal":{"name":"2020 International Youth Conference on Radio Electronics, Electrical and Power Engineering (REEPE)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126056774","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}

Analytical relations are given for the analysis and design of the original rotor with and without edge effects, in the presence of longitudinal slits with a bevel in the hollow rotor, depending on the low resonance frequencies (LRF). Electromagnetic processes in electromagnetic accelerometers are described by Maxwell's equations for slowly moving isotropic and conductive media. The peculiarity of the accelerometer operation is that when the rotor rotates at a certain constant speed, the resulting variable magnetic flux (due to the transverse reaction of the rotor), coupled to the measuring winding, induces an EMF proportional to the angular velocity of the rotor. This allows the accelerometer to work as a tachogenerator-unlike a standard accelerometer with a smooth hollow rotor that only measures angular acceleration. Due to its multi-functionality and improved metrological characteristics, this TA can be used in instrumentation and power engineering.","PeriodicalId":142369,"journal":{"name":"2020 International Youth Conference on Radio Electronics, Electrical and Power Engineering (REEPE)","volume":"486 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120897493","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}
