Further, we utilized the curved micro beams as the suspension springs to design a MEMS accelerometer with differential capacitive sensing mechanism in MEMS+ software. The dominant in-plane mode of oscillation with natural frequency of 7.98 kHz has been considered for the modal, and electromechanical analysis. The obtained results have shown that the accelerometer has maxium mechanical, and capacitive sensitivity of 0.0308 μm/g, and 27.211 fF/g respectively., for the radius of curvature of 2000 μm.","PeriodicalId":518961,"journal":{"name":"2024 IEEE Applied Sensing Conference (APSCON)","volume":"9 10","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2024-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140530661","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, the conventional fabrication methods of PVDF film requires complex methods, expensive equipments and several post treatments such as corona poling, stretching, annealing, quenching, etc. In this work, a simple, affordable, cost effective and less time-consuming procedures are used to fabricate a PVDF piezoelectric sensor. PVDF thin film was synthesized using simple solution casting method and aluminum foils were used as electrodes. With a load of 45 g, the proposed sensor generated 27 mV output piezoelectric voltage.

Since the heart is the body’s most important organ, it is crucial to spot anomalies in its functioning. Many researchers have examined various automated categorization techniques for heart sounds, which has been a topic of interest for decades. Thanks to machine learning techniques, large datasets of heart sounds may now be automatically evaluated. Recent studies have used support vector machines, and neural networks to categorize heart sounds more accurately. The highest reported accuracy of 0.99 was attained by a Convolutional Neural Network-based model that utilized the short-time Fourier transform and Mel-frequency Cepstral coefficients as features. However, the worth of the input signal and the variation in heart sounds between people can have an impact on how accurate these algorithms are. This paper exhibits the potential of machine learning models and deep learning models in classifying heart sounds.

Street lights are an elemental part of any city because they facilitate better night visibility, secured roads, and luminescence in public areas. Also, because street lights are present homogeneously on city roads, if they are used for wireless communication, other smart nodes can make use of their backhaul. In this paper, we present a smart street lighting system based on Wi-SUN (Wireless Smart Ubiquitous Network), which offers excellent redundancy owing to its use of a mesh topology. Wi-SUN is based on the IEEE 802.15.4g standard and uses license-free sub-GHz bands. We have used oneM2M as the middleware platform to enable possible interoperability with other smart city data verticals such as weather stations, environmental monitoring, crowd monitoring and so on. The proposed system provides a robust and low-cost method for controlling street lighting in any area, providing IP-addressable lighting. The proposed system additionally aims to provide consistent Wi-SUN coverage for future nodes in the area of deployment.","PeriodicalId":518961,"journal":{"name":"2024 IEEE Applied Sensing Conference (APSCON)","volume":"250 7","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2024-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140531158","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}
