In the device combining sensing, energy harvesting, data processing, edge computing, and wireless connectivity functionalities, the electromagnetic harvester's output is used for the vibration intensity sensing. The electromechanical core of the device is realized as an assembly of three free-standing polyethylene terephthalate membranes with an array of micromagnets attached to them. The vibration of the magnets in proximity to the microcoils induces an electric current in the circuit and enables the EEPROM bit writing operation. The number of the \u0000<sc>on\u0000/\u0000<sc>off\u0000 voltage switching and memory writing events in unit time, each corresponding to the stored energy threshold level crossing, is used as a condition monitoring indicator.

However, their use has largely been confined to uniaxial ferroelectrics, with multiaxial ferroelectrics remaining underexplored. In this letter, we introduce a newly constructed TENG based on a multiaxial ferroelectric material, 3,3-difluorocyclobutanammonium hydrochloride [(3,3-DFCBA)Cl], which showcases distinctive traits of multiaxial ferroelectricity, a strong piezoelectric coefficient (\u0000<italic>d\u000033\u0000) of 33 pC/N, and a remarkable piezoelectric voltage coefficient of (\u0000<italic>g\u000033\u0000) of 437.2 x 10\u0000-3\u0000 Vm/N, about twice than that of polyvinylidene difluoride, making it highly suitable for the emerging field of wearable sensors. Herein, the multiaxial ferroelectric material (3,3-DFCBA)Cl was incorporated into a polydimethylsiloxane (PDMS) composite, with electrospun polyvinyl alcohol fibers serving as the positive triboelectric layer. The resulting TENG device achieved the highest output voltage of 233 V and a maximum power density of 361 mW/m\u00002\u0000 under an optimal load of 20 MΩ for the optimized 10 wt% PDMS/(3,3-DFCBA)Cl composite device. In addition, the harvested energy proved effective for capacitor charging applications.","PeriodicalId":13014,"journal":{"name":"IEEE Sensors Letters","volume":"9 1","pages":"1-4"},"PeriodicalIF":2.2,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142912408","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}

Traditionally, firefighters rely on subjective visual descriptions transmitted via radios, leading to time-consuming and error-prone communication about their locations. This article presents an approach for far target detection (FTD) provided in terms of longitude, latitude, and altitude (LLA) coordinates in environments where GPS signals may not be available. Using LLA coordinates ensures concise communication among team members on their locations and provides a common coordinate reference system between outdoors/indoors. This article discusses the integration of three devices as a foundation for the FTD system. First, it uses zero-velocity-update (ZUPT)-aided inertial navigation systems (INS) via a foot-mounted inertial measurement unit (IMU) for personnel localization. Second, an augmented reality (AR) headset is employed to localize a handheld platform (HP) relative to the foot. Third, HP is used to determine the direction the firefighter is pointing at and to measure the distance to the objects. The system's performance was assessed through five experiments where a subject mapped a static point while walking a straight path demonstrating that the system is capable of achieving mapping precision within 2 [m] for distances on the order of 20 [m] from the target.","PeriodicalId":13014,"journal":{"name":"IEEE Sensors Letters","volume":"9 1","pages":"1-4"},"PeriodicalIF":2.2,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142905845","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}

Previously, it has been assumed that these scalar magnetometers have a flat response across their bandwidth and flat noise floor. Here, we show that standard fitting routines, used to extract the magnetic field, result in a nonlinear frequency dependent response across the sensor bandwidth, due to the time-averaged nature of such free precession measurements. We present an analytic correction dependent on dead-time, and show how this equation can also correct the sensor spectral density. The maximum in-band amplitude loss approaches 29% as the frequency of interest becomes the Nyquist frequency, making a significant correction for applications such as source localization in magnetoencephalography (MEG). These pump and probe atomic magnetometers are also known to have large aliasing of out-of-band signals, and we propose a scheme where the frequency of out-of-band signals can be identified by performing fits with varying dead-time on the raw free-precession sensor data.","PeriodicalId":13014,"journal":{"name":"IEEE Sensors Letters","volume":"9 1","pages":"1-4"},"PeriodicalIF":2.2,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142912435","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 accelerometer incorporates a high-temperature, up to 815 °C, piezoelectric (HTPE) transducer connected to a patented remote charge converter (RCC) via a high-temperature shielded hardline cable. The HTPE transducer contains a Parker Meggitt MC2 high-temperature crystal in shear mode as a sensing element. The RCC suppresses the transducer natural resonance resulting in extending its frequency bandwidth from 3 to 7 kHz at the level of ±5% and from 6 to 12 kHz at the level of ±3 dB. The accelerometer including RCC has a sensitivity of 3 mV/G and a frequency range from 3.5 Hz to 12 kHz at the level of ±3 dB. RCC's gain is fixed and equals 1 mV/pC. It can operate over a constant current range of 8 to 20 mA and at temperatures from −10 °C to +100 °C. RCC features small size and weight, two-wire output, and allows a transducer to have a resistance as low as 10 kΩ that typically takes place at extreme high temperatures. The small size (about 24 × 14 mm) and lightweight (30 g) of the HTPE transducer allows installation in narrow locations with minimal structural support.","PeriodicalId":13014,"journal":{"name":"IEEE Sensors Letters","volume":"9 2","pages":"1-4"},"PeriodicalIF":2.2,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142940807","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}

Alterations in the fornix region are significant biomarkers of AD. In this letter, an approach is proposed to distinguish mild cognitive impairment (MCI) from normal cognition (NC) and AD subjects using structural magnetic resonance (sMR) images and rotational invariant moments (RIMs). Initially, the sMR images are preprocessed using a standard pipeline, and the fornix structure is segmented using the reaction-diffusion level set (RDLS) algorithm. Then, a total of 11 RIMs are computed from the fornix region. Further, the significant features are identified using statistical tests: Shapiro–Wilk, Wilcoxon's rank-sum, and one-way analysis of variance. The results indicate that RDLS effectively segments the fornix structure. The RIM features demonstrate high statistical significance (\u0000<italic>p\u0000 < 0.01) in differentiating MCI from NC and AD, highlighting their ability to capture shape variations in the fornix. The proposed approach effectively differentiates MCI from NC and AD subjects, suggesting its clinical relevance in Alzheimer's condition analysis.","PeriodicalId":13014,"journal":{"name":"IEEE Sensors Letters","volume":"9 1","pages":"1-4"},"PeriodicalIF":2.2,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142905846","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}
