An MFC is a bioreactor that converts energy stored in chemical bonds of organic matter into electrical energy, through a series of reactions catalysed by microorganisms. An MFC can operate as bioreactor, as bioremediator and as biosensor. In the past decade, the evolution of low power electronics has made MFCs technology more attractive, because it has become suitable for low-power devices forming complete systems, such as the nodes of a WSN. Moreover, MFCs gained more interest because they can generate electric power while treating wastes. Unlike other fuel cells, MFCs can continuously generate clean energy at normal temperature and atmospheric pressure without any supplementary maintenance. Additionally, MFC may be used directly as a biosensor to analyse parameters like pH and temperature or arranged in the form of a cluster of devices to be use as a small power plant. A series of test was performed for the electrical valorisation of reactors as well as biosensor issues.","PeriodicalId":330672,"journal":{"name":"2019 IEEE 8th International Workshop on Advances in Sensors and Interfaces (IWASI)","volume":"356 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125641341","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 interface consists of a cascaded diode-connected load preamplifier followed by a reset integrator, which is used to convert the voltage signal to a pulse-width modulated (PWM) representation. The output is thus provided as a binary PWM waveform, which can be conveniently sent to a reader device using wireless communication and can be further converted to a digital representation using a simple counter. The flicker noise and the offset are eliminated using an approach similar to correlated double sampling. An input chopper is exploited to alternate the connection between the inputs of the preamplifier for each sample. The output signal is then extracted by subtracting two consecutive samples after conversion to the digital domain. In this way offset and low-frequency noise, which are correlated between the two samples, are effectively cancelled.","PeriodicalId":330672,"journal":{"name":"2019 IEEE 8th International Workshop on Advances in Sensors and Interfaces (IWASI)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134399446","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}

One function most of these interfaces have in common is signal rectification. Seeing how these interfaces are always on, their parts should have low power consumption. This leads us to the idea of an electromechanical rectifier for weak signal rectification that could increase the rectified voltage levels with no additional power consumption, as it would get the energy needed for its operation from the very phenomenon that is observed. Motivated by this application scenario, an electrical analysis of the weak signal detection utilizing a mechanically switched inductor was done, considering a low-impedance weak signal source. After the theoretical analysis, simulations of the proposed electromechanical topology were presented. Finally, an experimental demonstration was done utilizing an RMSHI circuit corroborating the applicability of this concept in weak signal detector for an always-on interface. The experimental results show that it is possible to detect a minimal input voltage between 40 mV and 50 mV peak-to-peak for the macroscopic RMSHI device.","PeriodicalId":330672,"journal":{"name":"2019 IEEE 8th International Workshop on Advances in Sensors and Interfaces (IWASI)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125405360","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}
