This paper reports the permanent frequency mismatch reduction of the primary wineglass modes in a planar axisymmetric resonator by strategic mass loading. The resonator consists of a set of concentric rings that are affixed to neighboring rings by a staggered system of spokes. The outer layers of spokes are targets for mass deposition. This paper develops modified ring equations that guide the mass perturbation process, and despite the fact that the deposited mass and deposition locations are quantized, it is possible to systematically reduce the frequency difference of the wineglass modes to effective degeneracy such that two modes cannot be distinguished in a frequency response plot. Results on five resonators are reported with nominal wineglass modes near 14 kHz, quality factors of 50k, and frequency mismatches exceeding 30 Hz in some cases, but with postperturbation mismatches smaller than 80 mHz. Furthermore, it is also shown that the quality factors remain unchanged.
This letter presents a micromachined silicon Lorentz force magnetometer, which consists of a flexural beam resonator coupled to current-carrying silicon beams via a microleverage mechanism. The flexural beam resonator is a force sensor, which measures the magnetic field through resonant frequency shift induced by the Lorentz force, which acts as an axial load. Previous frequency- modulated Lorentz force magnetometers suffer from low sensitivity, limited by both fabrication restrictions and lack of a force amplification mechanism. In this letter, the microleverage mechanism amplifies the Lorentz force, thereby enhancing the sensitivity of the magnetometer by a factor of 42. The device has a measured sensitivity of 6687 ppm/(mA · T), which is two orders of magnitude larger than the prior state-of-the-art. The measured results agree with an analytical model and finite-element analysis. The frequency stability of the sensor is limited by the quality factor (Q) of 540, which can be increased through improved vacuum packaging.
Tapered fibers are used in multitude of applications due to its great versatility and functionality. In particular, this type of fibers is especially useful for sensing applications. For this purpose, tapered fibers must be adequately manipulated to avoid disturbances in the sensor's response. In this paper, a guideline for the correct handling of biconical tapered fibers during refractive index and strain measurements is presented and analyzed considering several manipulation scenarios and its corresponding influence in the performance of the system.
Many changes are occurring in the physical, chemistry and biology processes of the ocean. Understanding how these changes are driven is an element of the key environmental descriptors identified by the European Marine Strategy Framework Directive (MSFD) with the ultimate goal being to protect the resource base upon which marine-related economic and social activities depend. The Directive furthers the ecosystem approach to the management of human activities having an impact on the marine environment, integrating the concepts of environmental protection and sustainable use. To meet these goals, in-situ data are necessary for comprehensive modeling and forecasting of ocean dynamics. Yet, collection of in-situ observations is inherently challenging from the perspective of both time and resources. This paper addresses a new generation of acoustic, optical and fishery in-situ sensors that address these challenges. These sensor systems are multifunctional (single sensor systems addressing several phenomena), can be deployed on a large majority of ocean monitoring systems from surface to the seafloor, and operate for long periods with less maintenance. In addition, at the system and user interface level, the publication of data uses processes and formats conforming to OGC SWE standards and consistent with global ocean observing initiatives and ocean modeling portals such as Copernicus marine environment monitoring services. During the last three years, NeXOS has achieved a number of milestones, providing ten new sensors along with important transverse capabilities for anti-fouling and data management. The optical sensors include monitoring of marine contaminants such as hydrocarbons and components of the carbon cycle. New sensor systems for passive acoustic measurements with extended dynamic range include internal post-processing of acoustic information to reduce communication loads. Two additional sensors (chlorophyll-a and oxygen) have been added to the RECOPESCA system to support an Ecosystem Approach to Fisheries (EAF) for improving measurement of stock-relevant parameters, such as fluorescence (proxy of chlorophyll-a) as well as physical parameters (T, S, Depth) and fish species. Interface with the sensors is through a miniaturized smart sensor interface common to all new NeXOS sensor systems and a PUCK implementation facilitates streamlined platform interfaces. A common toolset for web-enabled and reconfigurable downstream services supports marine databases and data facilitators, from SeaDataNet to GOOS and the Global Earth Observation System of Systems (GEOSS). This paper provides description of sensors and their capabilities along with validation testing.
Semiconducting metal oxide gas chemical sensors show promise for applications in handheld and personalized air quality monitoring systems. One limitation of these sensors is their cross-response to outdoor factors, such as temperature and humidity fluctuations. Previously, airflow (e.g., wind) was known to modify sensor output, but the cause of this response was not greatly characterized. In this paper, we investigate the effect of airflow on the output of a commercial metal oxide sensor in dry and humid air. Upon exposure to a step in airflow, the output of these sensors increases by more than 6% over 1 h. We also control the temperature of the sensor's embedded heater resistor using an external proportional-integral controller. With this control, the sensor output after exposure to airflow increases by <;1% over 1 h, demonstrating a stabilization scheme for air quality measurements that does not require additional temperature sensing equipment.
With a growing number of electric-field sensors becoming commercially available, there is an increasing need for high-quality test and evaluation processes. The electric-field sensing team at US Army Research Laboratory (ARL) possesses a low-frequency electric field “cage,” which provides a ~1-m3 volume with electric-field accuracy >99%. A state-of-the-art LABVIEW code has been developed to control laboratory equipment capable of generating uniform electric fields at frequencies of less than 20 kHz and magnitudes of less than 5 V/m. This paper characterizes the performance of three small electric-field sensors of two different types. Pairs of Plessey EPIC and QUASAR RVS electric potential sensors are tested in a fixture with a 60-mm separation distance. An integrated ARL “D-dot” sensor with an electrode area of ~15 mm by ~24 mm is also tested; this sensor responds to the time-derivative of the sensed electric field. These sensors are characterized in terms of frequency response, noise power spectral density, dynamic range, linearity, and total harmonic distortion. Characterization tests are performed over frequencies between 10 Hz and 10k Hz, and magnitudes between 4 mV/m and 4 V/m. We determined the RVS sensors give the flattest frequency response throughout our entire testing bandwidth, while the EPIC sensors have the lowest harmonic distortion at 0.65%.
This paper presents the optimal design of a rotating eddy-current probe using the inverse problem method.

In this study we present a concept of real-time and very inexpensive sensor for detection and recognition of micro poisons in aqueous solutions. The method is based on combination of advanced millimeter Wavelength (MMW) spectroscopy system and perfect absorber metamaterial (MM). The designed absorption line of the perfect absorber MM moves slightly due to substance presents in vicinity to the perfect absorber. This change is measured by a high-resolution and sensitive MMW spectroscopy system.
This paper presents a novel application of RF Compact Microstrip Resonant Cells (CMRC) coated with polyethylenimine (PEI) to form a high performance RF relative humidity (%RH) sensor. The single-port, short-circuit terminated CMRC sensor cell is coated with 5 uL of 10 w.t.% PEI diluted in methanol, and is coupled to the ultra-micro coaxial connector (UMCC) through a direction transmission line. The PEI coating coming in contact with humid air undergoes changes in both physical volume and dielectric constant, thereby shifting the resonant frequency of the CMRC sensor. The return loss (S11) measured near the resonant frequency of the sensor has seen an average humidity sensitivity of -16.2 mdB / %RH, with great linearity across the full range of relative humidity levels. All measurements are done at atmospheric temperature and pressure (ATM).
This paper presents a novel application of RF-filter parameter extraction techniques with coupling matrix model to obtain decoupled capacitive sensor readings from the S11 of a single-port, multi-resonator passive RF resonant sensor array. As an example application, two dual-resonator sensor arrays loaded with four selected functional polymers are implemented to allow ethanol and acetone identification. Through the parameter extraction techniques, the changes in capacitances of the sensor pair are obtained as chemical signatures to differentiate the presence of ethanol from acetone.
