Due to the features of wireless power and data transfer and non-line-of-sight interrogation of radio frequency identification (RFID), its innovative integration with different sensing elements has become a promising solution. Since the heartbeat and respiration signals are weak and their measurement is time-consuming, a lightweight and flexible solution for their unobtrusive wearable sensing remains a challenge. This investigation presents a novel capacitive pressure sensor (CPS)-augmented RFID solution for simultaneous and wearable sensing of heartbeat and respiration. The main contributions include: first, proposal of an innovative RFID-based vital sign monitoring scheme, which integrates a CPS for heartbeat sensing and employs RFID phase signals for respiration sensing; second, design and fabrication of a polydimethylsiloxane (PDMS)-based flexible and porous slotted CPS for continuous heartbeat sensing; and third, development of respiration signal reconstruction algorithm using the weak and noisy RFID phase integrating phase disambiguation, denoising, baseline removal, and peak detection. Experimental studies are conducted to verify the feasibility and effectiveness of the presented techniques.","PeriodicalId":13014,"journal":{"name":"IEEE Sensors Letters","volume":"9 4","pages":"1-4"},"PeriodicalIF":2.2,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143667611","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}

Single pot electrodeposition has been engaged in fabricating PANI/PTA/Cu composite on FSS via cyclic voltammetry (CV). The successful composite fabrication has been authenticated through physicochemical characterization, including its structural geometry, surface morphology, and molecular vibrational properties, which were analyzed through X-ray crystallography, field emission scanning electron microscopy, infrared spectroscopy and UV-Vis spectrophotometers. The electrochemical sensing performances were examined using CV and chronoamperometric analysis. The flexible sensor measured a sensitivity of 3.79 mA/mM with a detection limit of 7.9 µM for AA. This performance results from the combined synergetic action of PANI, PTA, and Cu, which enabled efficient ionic diffusion and seamless electron transfer through a high density of accessible electroactive sites. In addition, the flexible sensor electrode exhibited remarkable selectivity for AA, with negligible interference from coexisting species, highlighting its potential for healthcare diagnostic applications in near future.","PeriodicalId":13014,"journal":{"name":"IEEE Sensors Letters","volume":"9 7","pages":"1-4"},"PeriodicalIF":2.2,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144255740","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, these sensors are vulnerable to environmental contamination, particularly from muddy water, which can significantly degrade their optical performance. This letter presents a standardized method for evaluating the impact of muddy water contamination on recognition sensor cover with a focus on assessing transmittance reduction. An automated injection system was employed to apply varying levels of contamination to polycarbonate windows, and transmittance was estimated based on a pulsed laser module. The proposed method demonstrated that practical applicability was achieved by comparison with real-world contamination during test driving and laboratory findings. This research will provide a reliable, standardized approach to quantify the effects of various contaminations on sensor performance, also contributing to the development of more robust autonomous driving technologies capable of operating in harsh environmental conditions.","PeriodicalId":13014,"journal":{"name":"IEEE Sensors Letters","volume":"9 4","pages":"1-4"},"PeriodicalIF":2.2,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143769410","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}

Here, highly oriented DPPT-TT floating films were prepared on a liquid substrate using the unidirectional floating-film transfer method (UFTM) and then utilized as the active layer. This innovative approach exhibits a dual-orientation advantage: They align polymer chains unidirectionally, enhancing charge transport along the backbone while simultaneously promoting an edge-on molecular arrangement relative to the substrate. This combination, coupled with highly uniform thin films, facilitates efficient charge transport pathways, contributing significantly to the fabrication of high-performance OPTs. Our DPPT-TT-based OPT exhibited a high field-effect mobility of 1.5 cm2·V−1·s−1 and photoresponsivity (R) > 105 A·W−1 at an intensity of 45 <italic>μW·cm−2 under 810 nm light illumination.

Traditional chemiresistive CO<inline-formula><tex-math>$_{2}$</tex-math></inline-formula> sensors have high operating temperatures that require external heating elements limiting their applicability in low-power portable electronics. This work demonstrates a miniaturized printed CO<inline-formula><tex-math>$_{2}$</tex-math></inline-formula> gas sensor, based on aluminum-doped zinc oxide (AZO) and silver nanowire (Ag NW) nanocomposite ink, which operates efficiently at room temperature. The AZO-Ag NW nanocomposite ink is optimized for direct ink writing (DIW) to obtain a uniform printed pattern. The composite ink helps overcome the inherent high resistance of AZO nanostructures by taking advantage of Ag NW's high conductivity and surface reactivity. The sensor shows a quick response time of 19 s and a recovery time of 36 s for 400 ppm CO<inline-formula><tex-math>$_{2}$</tex-math></inline-formula>. The sensor exhibits a response (R) of 32.5% with a limit of detection of 24.04 ppm, while operating at a low bias of 1 V.
