To reduce the cost and complexity of these instruments, in this letter, we developed a simple circuit for rapid LED pulsing and accurate timing synchronization and implemented it in a compact TRL imager with a ultraviolet light emitting diode (UV LED) as a light source and a chopper-coupled smartphone camera as a time-gated optical detector. The TRL measurement of this imager using this circuit was successfully validated through an anticounterfeiting application. We believe that this simple circuit can be adopted in the development of low-cost and compact TRL measurement instruments for broad point-of-care or in-field applications.","PeriodicalId":13014,"journal":{"name":"IEEE Sensors Letters","volume":"9 3","pages":"1-4"},"PeriodicalIF":2.2,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143446329","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 system was able to record the change in <inline-formula><tex-math>$f_{0},(Delta f)$</tex-math></inline-formula> caused by mass loading to the NFC's electrically erasable programmable read-only memory. The <inline-formula><tex-math>$f_{0}$</tex-math></inline-formula> measured using the proposed system was then validated against impedance analyzer measurement, and the maximum error was measured to be 0.0004%. An Android application was then developed to read log <inline-formula><tex-math>$f_{0}$</tex-math></inline-formula> using a smartphone. Further, we demonstrated wireless measurement of the mass loading rate of a dc sputtering system, a well-known vacuum deposition technique adopted in semiconductor process industries.

This research introduces two key innovations: the wearable low-cost PPG acquisition device (WeLOVE) and the RespTrack-Net model. The WeLOVE device is designed to provide high-quality PPG signal acquisition at low cost, addressing the accessibility challenges of current systems. The RespTrack-Net model introduces a novel architecture tailored for extracting respiration rate (RR) and cardiovascular parameters with enhanced robustness to noise and motion artifacts. The proposed approach was validated using two datasets: an experimental database (eight subjects) collected in this study and the publicly available CapnoBase database (42 subjects). RespTrack-Net achieved mean absolute errors of 1.58 <inline-formula><tex-math>$pm$</tex-math></inline-formula> 1.30 and 3.16 <inline-formula><tex-math>$pm$</tex-math></inline-formula> 3.36 for RR estimation on these datasets, respectively, outperforming State-of-the-Art methods. These contributions demonstrate the system's novelty and potential for reliable, real-time health monitoring in diverse settings.
