The resonant frequency of ultrathin MoS2 resonators is extremely sensitive to the intrinsic strain of the membrane. We utilize the resonant frequency shift caused due to change in strain to demonstrate the potential of these devices for ultrasensitive temperature sensing. The temperature coefficient of frequency (TCf) of the MoS2 drum resonator is estimated to be −283 ppm/K. We also report the first study on the frequency stability of MoS2 resonators at room temperature. The Allan deviation of these resonators is ~5 × 10−5 at an integration time of 1 second. This study estimates the ultimate temperature detection limit of MoS2 membrane-based device.","PeriodicalId":6775,"journal":{"name":"2021 IEEE Sensors","volume":"117 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":"80996637","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}

PZT and all conventional piezoelectric materials are weak, and prone to fracture. In addition, PZT is not able to withstand high temperatures. High temperature materials are available, but these are also extremely fragile and have low piezoelectric coefficients, in particular, the shear mode sensitivity. We report here on a new class of piezoelectric materials, the Ionix HPZ family, far stronger than PZT, which allows engineers to use them in a high shock environment, at significantly higher temperatures, in both thickness and shear mode. These materials have excellent compatibility with other engineering materials in sensor manufacture, such as steel and titanium.","PeriodicalId":6775,"journal":{"name":"2021 IEEE Sensors","volume":"4 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":"82996290","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}

These printed sensors can allow for data acquisition within industries transitioning to data-informed decision-making. One such industry is agriculture, where soil data can inform decisions to increase crop yield while protecting the environment. In this work, we demonstrate a novel, dual-printed multi-functional soil sensor that can detect nitrate levels in saturated soil while also quantifying the moisture level. The nitrate sensor utilizes an electrochemical approach and can detect nitrate values from 5 to 400 mg/L within a saturated silt loam soil. The moisture sensor uses capacitance proximity sensing to measure the moisture of the soil based on changes in the dielectric permittivity and was able to measure moisture in sandy soil ranging from 0.1 to 0.25 m3/m3. The dual-printed sensor is expected to allow for quantifiable nitrate leaching when placed in a distributed manner through multiple direct nitrate and moisture measurements.","PeriodicalId":6775,"journal":{"name":"2021 IEEE Sensors","volume":"48 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":"78192567","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}

To meet the requirement of simultaneously tracking of multiple surgical instruments in clinical application scenarios, we propose a probabilistic filtering approach to realize multi-magnet positioning. The tracking system includes a magnetic sensor array and magnetic targets. Random walk model has been used to formulate the system equation, and the measurement equation is established with the magnetic dipole model. Based on the Extended Kalman Filter (EKF) algorithm, the nonlinear problem can be solved by estimating the positions and orientations of multiple magnets. The feasibility of the proposed method is verified by both static and dynamic experiments. The results show that the filtering-based multi-target magnetic tracking algorithm enables low-latency tracking with reasonable accuracy.","PeriodicalId":6775,"journal":{"name":"2021 IEEE Sensors","volume":"99 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":"77210632","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 paper we compared two magnetic wires, one with slightly negative and one with slightly positive magnetostriction in their as cast state and we anneal them measuring then how the magnetostriction and the noise evolves as we increase the annealing time.","PeriodicalId":6775,"journal":{"name":"2021 IEEE Sensors","volume":"30 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":"87103650","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}
