Traditionally, disease identification relied solely on the expertise of medical professionals. However, limitations in physician availability, particularly in resource-constrained regions, can hinder timely diagnosis. Fortunately, data analysis techniques are now widely employed to address a multitude of medical disease detection. This paper presents a novel Pneumonia disease detection model by analyzing the chest X-ray data. The development of robust diagnostic tools faces a critical challenge: the lack of access to large, labeled training datasets. This challenge arises because of privacy concerns about medical data. This research proposes a solution that tackles both data scarcity and privacy concerns. It leverages an unsupervised learning model trained on decentralized datasets. The unsupervised learning approach used is an Autoencoder neural network, and the decentralized learning technique used for model training is Federated Learning. The proposed approach trains the model on data residing at multiple locations, such as healthcare institutions, without compromising patient privacy. The datasets used to train the proposed model consist of chest X-ray images of pneumonia patients and healthy individuals. It offers satisfactory performance when compared to other existing Pneumonia detection models. In similar studies, medical institutions can collaborate and develop efficient medical tools without breaching patients’ data privacy.</div></div>","PeriodicalId":34311,"journal":{"name":"Measurement Sensors","volume":"37 ","pages":"Article 101410"},"PeriodicalIF":0.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143143856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through multidimensional experiments such as static testing, dynamic testing, and temperature testing, comprehensively evaluate the performance of gallium nitride barrier based microelectromechanical systems in intelligent agricultural sensor networks. The static test results indicate that with the increase of external force, the electrical response of the system shows a significant improvement, and there is a high linear correlation between external force and electrical response (R<sup>2</sup> = 0.987). In dynamic testing, as the vibration frequency increased from 1Hz to 1000Hz, the electrical response gradually strengthened, demonstrating the system's good adaptability under high-frequency vibration. However, power consumption also increases with the increase of vibration frequency. The temperature test results show that there is a positive correlation between electrical response and power consumption in the temperature range of −20 °C to 60 °C, indicating that gallium nitride technology can effectively improve the sensitivity, stability, and adaptability of micro nano scale electromechanical systems under different environmental conditions.
