A network of immobile wireless sensors equipped with acoustic transceivers, storage capacitors and with known cartesian coordinates in a 2D plane is considered. A power delivery vehicle (PDV) with finite energy storage capacity is used to recharge a sensor node’s supercapacitor which then transmits power to neighboring sensors acoustically within range. This work aims to find an optimal charging route for the PDV. The proposed algorithm is a combination of cluster analysis and breadth-first search. A theoretical study was performed, and the simulation results obtained were studied for the long-term failure probability for the proposed energy scheme.","PeriodicalId":6648,"journal":{"name":"2019 19th International Conference on Micro and Nanotechnology for Power Generation and Energy Conversion Applications (PowerMEMS)","volume":"80 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74812877","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}

The developed FEM is able to precisely predict (1) the maximum power output at each frequency without the tedious load-resistance sweeping approach traditionally used; (2) the dual-power-peaks phenomenon of highly-coupled PEHs, which cannot be observed when using the traditional approach of $R_{opt}=1/omega C_{P}$.

The flapping airflow energy harvester consists of a cantilever beam structure with a wing at its free end. A bluff body is placed in front of the wing to induce aerodynamic instability that leads to up and down oscillation of the wing. By coupling transducers to the oscillating wing, electromagnetic in this case, electrical energy can be generated. In this research, instead of using a commonly used rigid wing, the proposed airflow energy harvester has flexible wing sections that are able to bend, thus reduce the aerodynamic resistance during the wing oscillation. Therefore, the overall mechanical damping can be reduced and output power of the proposed energy harvester is increased. It is found experimentally that the proposed method is able to improve energy harvester performance of flapping airflow energy harvesters under high airflow speeds.","PeriodicalId":6648,"journal":{"name":"2019 19th International Conference on Micro and Nanotechnology for Power Generation and Energy Conversion Applications (PowerMEMS)","volume":"6 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90771246","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}

However, there are few studies for energy harvesting from rotational motion when the rotational speed is less than 120 rpm (2 Hz). In this paper, an inverse nonlinear piezoelectric energy harvester (PEH) is proposed for enhancing performance in low-frequency rotational motion via the centrifugal softening effect. In addition, according to Lagrange equation, the related theoretical model is derived. Furthermore, the experiments between the forward and inverse configurations in rotational motion are conducted under the rotational speeds ranging from 60 rpm to 160 rpm. The experimental results demonstrate that in low-frequency rotational motion the inverse PEH exhibits outstanding performance with the RMS voltage as high as 5 V, which is enough for powering some wireless sensors. Overall, the centrifugal softening effect is verified to be an effect method for energy harvesting in low-frequency rotational motion.","PeriodicalId":6648,"journal":{"name":"2019 19th International Conference on Micro and Nanotechnology for Power Generation and Energy Conversion Applications (PowerMEMS)","volume":"18 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87426930","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}

It was described that the holding force of the EPM significantly depended on the activation process, and it was important to realize the full activation to exploit the potential performance of the EPM. Then, it was shown that the resonance frequency of the cantilever oscillator can be changed from 26Hz to 42 Hz when the EPM placed in the middle of the beam was fully activated, while the partially activated EPM could not maintain the resonance because of its weak holding force.","PeriodicalId":6648,"journal":{"name":"2019 19th International Conference on Micro and Nanotechnology for Power Generation and Energy Conversion Applications (PowerMEMS)","volume":"6 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85378378","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}
