This discomfort can be reduced by integrating tiny super-capacitors as an energy source for the device. The external wireless telemetry unit used to activate and interrogate the implantable device charges the super capacitors integrated on it. When the wireless telemetry unit is removed, the super capacitor powers the implantable device. This paper shows the benefits of integrating super capacitors onto an existing pressure sensing medical implant that utilises an inductive telemetry link. Test results show that the implant can be powered for a full day using an 88 mF super capacitor. This super capacitor can be fully charged using the inductive telemetry link at a wireless distance of 20 cm in 81 seconds.","PeriodicalId":384458,"journal":{"name":"2018 14th Conference on Ph.D. Research in Microelectronics and Electronics (PRIME)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122913072","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}

They need to be controlled by some battery management system (BMS) to maintain the batteries working in a safety range, estimate the state of charge, the state of health and to maximize the energy stored. Software simulation allows to improve the BMS algorithms but they need to be validated on real BMS and cells. This paper presents an HW platform composed by a custom open-source BMS with a standard Arduino Uno compatible pinout, a battery charger, six lithium cells, and the software that manages the test. The platform is validated by using a passive cells balancing algorithm and a charging algorithm that interacts between them. The test shows as during the passive balancing the algorithm must take into account also the temperature of the board.","PeriodicalId":384458,"journal":{"name":"2018 14th Conference on Ph.D. Research in Microelectronics and Electronics (PRIME)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132846198","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}

A negative feedback is used to automatically produce short anodic pulses according to the remaining voltage. The period of the short anodic pulses varies according to the remaining voltage. Thanks to the structure of the static comparator, the system produces pulses with high duty-cycle at the beginning of the anodic phase and low duty-cycle at the end of the anodic phase. Hence, the system can accurately balance the charge. In contrast with previous methods based on the chopped anodic phase, this method employs a new structure that reduces the area of charge balancer for integration and increases the accuracy for a safe electrical stimulation. Lowering the power consumption of the charge balancing circuit is another outcome of the proposed method. An integrated circuit implementing the proposed method is designed using a $0.18 mu mathrm {m}$ technology. The simulation results prove the accuracy and proper performance of the proposed method in both current and voltage mode stimulation.","PeriodicalId":384458,"journal":{"name":"2018 14th Conference on Ph.D. Research in Microelectronics and Electronics (PRIME)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134110430","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}
