The measurement is based on an evaluation of the magnetic field outside the cable. A sensor-device based on this approach can be installed without removing any part of the isolation, separating the conductors inside the cable or even turning of connected electrical consumers. It is therefore considered noninvasive. Based on this approach a sensor-device is developed and tested. A maximum measurement deviation of 4 percent is achieved.","PeriodicalId":6775,"journal":{"name":"2021 IEEE Sensors","volume":"26 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79662901","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}

Among water contaminants are heavy metal ions such as Fe3+, which is commonly used in industries such as mining, chemical processing, and battery manufacturing. Fe3+ is the principal contaminant of concern in acid mine drainage from coal mines, causing siderosis and organ damage. The current study prepared highly photoluminescent nitrogen-doped functionalized carbon spheres (N-CSs) from corncob residue using a facile, green, and low-cost microwave synthesis. The as-prepared N-CSs exhibited an excitation-dependent fluorescence with a maximum emission and excitation at 420 and 340 nm, respectively and showed good selectivity and sensitivity towards the detection of Fe3+ with a 70 nM limit of detection.","PeriodicalId":6775,"journal":{"name":"2021 IEEE Sensors","volume":"70 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77081706","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}

In this study, we present an automated color detection system to perform qualitative analysis of liquid reagents. Many of the available techniques for colorimetric applications make use of expensive, high-resolution digital cameras. We have developed a simple low-cost system based on a light emitting diode (LED) and light-dependent resistor (LDR) pair to obtain information about the color of a liquid reagent. This system has been compared with a camera-based system for color detection. The LED-LDR system provides information about the color of an object by obtaining relative intensities of red, green, and blue (RGB) light reflected by the object in a sequential process. The system was tested by obtaining color information for different concentrations of potassium permanganate solution and by determining the endpoint of a titration experiment. This versatile system can be used for many other colorimetric measurements, for example, the amount of dissolved ammonia in water using Nesslers reagent (potassium tetraiodomercurate).","PeriodicalId":6775,"journal":{"name":"2021 IEEE Sensors","volume":"73 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76923930","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}

A piezoelectric resonating membrane with frequency of about 100kHz is used as high precision microbalance operated in flexural mode. The natural frequency shift is proportional to the extra mass added on its surface and can be related to the particle concentration in the sampled air-volume. The vibrational spectrum is recorded by means of a vibrometer and the mass sensitivity is then evaluated by measuring the frequency shift adding extra mass of calibrated PM5 particles (Silica beads) on the membrane surface. The feasibility study has experimentally showed real-time detection performance to standard silica micro-spheres. The sensor is promising in applications of personal portable air pollution monitoring and analysis.","PeriodicalId":6775,"journal":{"name":"2021 IEEE Sensors","volume":"3 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76988082","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}

It contains a main thread and six sub-threads, and a combination of signal and slot mechanisms to accomplish the online recognition task. Data reception, data packetization and feature extraction are designed to be fulfilled in the main thread. Real-time data presentation, data storage, feature storage and real-time images are performed in four sub-threads. Aiming for the online mode, a sub-thread to update the data is designed. The CUSUM-MLP algorithm is packed as a sub-thread for event detection and load identification.

To provide reliable sensors that can withstand industrial applications, we have developed a soft and thin-film tactile sensor capable of detecting tri-axis force components including normal and shear forces. The thickness of the sensor is 5.5 mm, and the sensor can be easily attached on an end-effector. Two layers of capacitive-sensing-electrode arrays sandwiching an elastomer layer of 2-mm spatial resolution are embedded in soft material, and output signals are distributed. To measure the external force vector, center-of-distributed-signal calculation was conducted. Our sensor exhibited linear behavior within 0.1 to 10 N for normal force and 0.1 to 4 N for shear force. With high reliability, sensor sensitivity did not change over ±10.0% even after one million repetitive keystroke cycles and one million repetitive shear-movement cycles. To determine the sensor’s effectiveness for manipulation tasks, a grasping-force control experiment was conducted using sensor signal feedback, and multiple local-shear-force vectors were successfully calculated using area-divided methods.","PeriodicalId":6775,"journal":{"name":"2021 IEEE Sensors","volume":"22 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73415794","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}
