Instead, they rely on retaining their state, i.e. a snapshot, in non-volatile memory (NVM) in the event of a power outage and restoring it when the power recovers. In this paper, we first discuss the limitations of state-of-the-art techniques that attempt to minimize the amount of system state saved to NVM. Therefore, we propose a novel energy-efficient system-level approach for state retention through memory tracing based on a custom hardware module named MeTra that traces changes in the main (volatile) memory between power outages. MeTra allows the voltage threshold that activates the state retention process to be dynamically adjusted according to the energy requirement of each snapshot. Thus, a great proportion of the energy harvested can be spent on useful operations. Experimental results show that the system’s active time can be extended up to 17x for Flash-based systems and 92.2% for FRAM-based systems, compared to saving the entire system state, with an area overhead of as little as 2.48%.","PeriodicalId":261827,"journal":{"name":"2023 9th International Workshop on Advances in Sensors and Interfaces (IWASI)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129330651","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}

Over the years, health research has included different areas, ranging from specific therapies to patients’ lifestyle and social information: “patient-oriented” approaches have increasingly emerged as a crucial tool for health care systems, as clearly shown during the recent SARS-CoV-2 pandemic. In this context, the synergy between different scientific and technological fields, such as biology, chemistry, physics, and engineering, is increasingly considered an essential requirement. This work presents a low cost and easy-to-use sensor of volatile organic compounds (VOCs) in exhaled breath, with the purpose of serving as a rapid, non-invasive and versatile diagnostic tool in smart medicine applications. A “lock-and-key” system relying on gold nanoparticles deposited on cotton fabric enables the detection of target molecules, whose adsorption produces variations in terms of electrical impedance. The system has been exposed to ethanol-based solutions in an experimental campaign to investigate the sensing capabilities at 1 Hz - 1 MHz frequency range. The results achieved demonstrate the feasibility in obtaining health-relevant VOCs detection based on impedance analysis.","PeriodicalId":261827,"journal":{"name":"2023 9th International Workshop on Advances in Sensors and Interfaces (IWASI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130634566","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 MS is comprised of different pixels, each designed to monitor a specific region of the electromagnetic spectrum. These pixels are engineered with plasmonic resonances that match the Amide I and Amide II vibrational bands in the range of 1500-2000 cm-1. The proposed MS allowed a label-free spectroscopic characterization of a solution of biofibers isolated from cultured fibroblasts treated with an oligothiophene based oligomer. The reflection spectra acquired on areas containing a biofiber show the presence of the typical Amide I and Amide II vibrational bands, while reflection spectra acquired outside the fibers show no signal. Additionally, the evaluated enhancement factor (up to 1.4·103) enables the detection of very small amounts of material bound on the proposed platform, as in the case of a biofiber placed on the nanoantennas composing the MS pixels.","PeriodicalId":261827,"journal":{"name":"2023 9th International Workshop on Advances in Sensors and Interfaces (IWASI)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126581901","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}

Early detection of seizures is crucial for preventing these outcomes by enabling timely intervention. However, clinical detection of neonatal seizures is challenging due to the lack of physical symptoms and limited access to experts in EEG analysis. Artificial Intelligence (AI) has emerged as a popular tool to assist medical professionals in interpreting EEG signals and detecting seizures. A novel method of AI assisted EEG sonification was introduced to compensate for the lack of explainability in AI’s decisions. This method uses sound to detect seizures intuitively while exploiting AI’s effectiveness as an attention mechanism. Besides low power consumption, the real-time operating capability is also essential for adapting this algorithm in clinical settings, which is unattainable with the offline processing approach used in previous studies. This study presents a scalable and real-time adaptation of this algorithm with an ultra-low power implementation. This application provides continuous audio output for medical workers, allowing for immediate access to audio analysis of the EEG signals. An on-chip ultra-low power neural network accelerator enables the implementation to scale up the number of monitored EEG channels. The real-time algorithm has an average power consumption of 13 milliwatts, allowing it to operate for more than eleven days on a mobile phone battery with a capacity of 3500 mAh.","PeriodicalId":261827,"journal":{"name":"2023 9th International Workshop on Advances in Sensors and Interfaces (IWASI)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133412678","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}
