However, demonstrations have so far been restricted to laboratory-based experiments using relatively bulky apparatus and requiring manual handling of the diamond sensing element, hampering broader adoption of the technique. Here a simple, compact device that can be deployed outside a laboratory environment and enables robust, simplified operation is presented. It relies on a specially designed sensor head that directly integrates the diamond sensor while incorporating a microwave antenna and all necessary optical components. This integrated sensor head is complemented by a small control unit and a laptop computer that displays the resulting magnetic image. The device is tested by imaging a magnetic sample, demonstrating a spatial resolution of 4 µm over a field of view exceeding 1 mm, and a best sensitivity of 45 µT <math></math> per (5 µm)2 pixel. The portable magnetic imaging instrument may find use in situations where taking the sample to be measured to a specialist lab is impractical or undesirable.","PeriodicalId":100037,"journal":{"name":"Advanced Sensor Research","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adsr.202400108","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143112169","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}

Incorporating functionalized carbon nanotubes (f-CNTs) into PEI developed in recent years has remarkably enhanced sensor performance. However, the active characteristic of imine groups makes the sensor susceptible to aging. In this research, the aging of PEIs with different molecular weights is systematically studied and compared along with their thermal stability and structure migration under various conditions, explored using thermogravimetric analysis and Fourier-transform infrared spectroscopy. Furthermore, an ink composed of high-molecular-weight PEI and f-CNTs is successfully developed, which shows outstanding printability according to its rheology results. The stability of the ink is assessed by a Turbiscan analyzer and compared with the ink composed of low-molecular-weight PEI. The ink with high-molecular-weight PEI is utilized to prepare CO2 sensors via screen printing, which are then tested by in-house-built electronics. The sensors achieve a detection range of 300–2000 ppm CO2, which could indicate robust sensing performance even after 40 continuous testing cycles. It should be noted that the resultant sensors have realized a wider measurement range and superior stability than other reported PEI/CNT-based CO2 sensors, further facilitating their practical applications.","PeriodicalId":100037,"journal":{"name":"Advanced Sensor Research","volume":"4 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adsr.202400062","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143379919","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}

Rapid and precise detection of these arrhythmias is crucial for their termination by closed-looped therapeutic interventions to counteract detrimental effects. However, there is a current lack of such systems tailored for experimental cardiovascular applications. This hampers not only in-depth mechanistic studies but also translational testing of new therapeutic strategies, especially in an untethered manner in awake animal models. To break new ground, recent advances to develop a non-invasive AI-supported heart rhythm monitoring system for untethered automated arrhythmia detection in a continuous manner is combined. This system is housed in a lightweight jacket for mobile use and includes an on-skin ECG sensor, a low-power microprocessor unit, a massive data storage unit, and a power-management system. By implementing a novel hybrid algorithm based on so-called heart rate (R-R) variability and a case-specific AI model, 100% sensitivity and 95% specificity is achieved in detecting atrial arrhythmias within 2 s upon initiation in adult rats. Thereby, the novel system sets the stage for advanced mechanistic studies and therapeutic testing, including closed-loop applications aiming for the termination of a broad range of atrial arrhythmias.","PeriodicalId":100037,"journal":{"name":"Advanced Sensor Research","volume":"3 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adsr.202400057","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142642534","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}

In this work, aluminum ferrite (AlFeO3)/PVDF hybrid perovskite electrospun nanofiber-based tribo-enhanced piezoelectric nanogenerators (TPENGs) are developed for energy harvesting. The as-fabricated TPENG achieves an average voltage output of 52.3 V and an average current output of 1.23 µA. Additionally, the power density of the TPENG is calculated to be 0.085 W.m−2 at an 80 MΩ external resistance load. A 3D-printed device is fabricated, containing nylon fabric (tribo-positive) as a rotor attached to printed fins, while six (AlFeO3)/PVDF hybrid perovskite electrospun nanofiber piezoelectric nanogenerators (PENGs) wrapped with Kapton tape (tribo-negative) serve as the stator. The three printed fins of the device are moved by a string-based pulley, generating an open circuit voltage of 200 V and a short circuit current of 4.5 µA. The as-fabricated 3D-printed device with TPENGs is used to power small electronics (e.g., LEDs and watch) and an exercise setup, allowing patients to generate power by pulling the attached string, thereby estimating the level of impairment. Integrating energy harvesting into rehabilitation motivates patients to move impaired body parts, enhancing TPENG's application in healthcare as a practical and engaging tool for patient rehabilitation.","PeriodicalId":100037,"journal":{"name":"Advanced Sensor Research","volume":"3 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adsr.202400023","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142170272","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}

Here passive wireless, multimineral comonitoring arrays are studied that may potentially be utilized for emerging applications in precision nutrition. RF biosensors targeting select minerals (calcium or magnesium demonstrated herein) are built from integrating ion-selective membranes within a broadside-coupled split ring resonator architecture. RF sensors are typically monitored one at a time and such platforms often are incapable of comeasuring multiple confounding components. To address this challenge, this sensor arrays are further directly integrated alongside a conformal, custom readout coil that optimizes multi-RF sensor readout. Such optimized networks exhibit enhanced signal clarity, further facilitating coextraction of multiple ion components. A simple method of extracting multimineral concentrations from food even despite the imperfect selectivity of divalent ion-selective membranes is introduced. This passive wireless, zero-electronic ion-monitoring platform integrates seamlessly on foodware or packaging, possessing many applications in food measurement.","PeriodicalId":100037,"journal":{"name":"Advanced Sensor Research","volume":"3 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adsr.202400054","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142642435","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}

UTIs can significantly reduce the quality of life and, in severe cases, result in sepsis and mortality. According to Public Health Ontario, over 80% of long-term care home (LTCH) residents with asymptomatic bacteriuria are treated with antibiotics, however, less than 50% of the antibiotic treatments for UTIs show clinical benefit. Current confirmatory processes for UTIs are primarily dependent on the completion of urine cultures which can result in a delay of more than 24 h. Therefore, there is a need to develop new efficient diagnostic methods to provide timely test results and prevent multidrug resistance. Emerging nanomaterials with special physical and chemical properties have demonstrated great potential in rapid detection of UTI-associated bacteria. This review paper provides a thorough analysis of current diagnostic tools for UTIs. Emerging nanostructured biosensors are reviewed to elucidate the most recent progress in the detection of uropathogens. It is believed that advanced biosensors integrated with nanotechnology will contribute to the timely diagnosis of UTIs and improve the accuracy of the results, which will lead to better treatment of this prevalent clinical condition.","PeriodicalId":100037,"journal":{"name":"Advanced Sensor Research","volume":"3 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adsr.202400051","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141828808","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}
