To enhance the sensitivity of the piezoelectric accelerometer, we report a novel series-connected multicapacitor pickup MEMS design. Using well-calibrated COMSOL simulations, we show that the number of series-connected integrated capacitors in the construction directly correlates with the differential sensitivity of the multicapacitor piezoelectric accelerometer. In this technique, the voltage across all the series capacitors in the structure is equal to that across the single-capacitor structure. A multicapacitor pickup structure can be designed using two, four, six, or more capacitors. The design is demonstrated using aluminum nitride (AlN) as a piezoelectric material, but it can be extended to other materials such as lead zirconate titanate (PZT) and zinc oxide (ZnO). Furthermore, we have developed a mathematical model for the multicapacitor structure of the piezoelectric accelerometer, and the results are compared with the simulated data, showing excellent accuracy with an error of less than 4%. The proposed method demonstrates significant potential for improving the efficiency of various vibration-sensing/energy-harvesting MEMS structures. The device proposed in this work has a wide range of applications, including autonomous systems, machine/structure health monitoring, and navigation systems.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 18","pages":"35418-35425"},"PeriodicalIF":4.3,"publicationDate":"2025-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145073215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the ground reaction force (GRF) of each leg has not been well characterized due to its difficulty in measurement. In this report, a micro force plate array is presented that uses the sampling Moiré (SM) method, a prism, and a single camera to simultaneously measure the triaxial GRFs of multiple legs of an ant during its locomotion. The SM method is a high-resolution measurement method that measures the amount of displacement based on the shift of a captured grid pattern. The proposed micro force plate array consists of a <inline-formula> <tex-math>$3 times 3$ </tex-math></inline-formula> array of <inline-formula> <tex-math>$2900 times 2900 times 70 ; mu $ </tex-math></inline-formula>m plate bases with a gap of <inline-formula> <tex-math>$100 ; mu $ </tex-math></inline-formula>m as the contact surface of the ant legs. The plate base is supported by a spring structure with a grid pattern. By capturing this grid pattern from the backside via a prism, a camera can capture images from two different directions, allowing the triaxial displacement to be measured. By dividing the plate surface into nine sections and evaluating the error based on the position of the force application in the z-direction force, a maximum measurement error of 6% was found. The average force resolution in the x-, y-, and z-directions for the nine plates was 3.34, 2.47, and <inline-formula> <tex-math>$1.20 ; mu $ </tex-math></inline-formula>N, respectively.

For the prediction accuracy of the model, this article analyses the influence mechanism of the gas temperature change of the MEMS thermal mass flow sensor. The functional relationship between the fitting flow rate, gas temperature and actual flow rate is constructed using a binary regression equation, which eliminates the measurement error caused by gas temperature change.

It also has potential to be produced as array configurations at low cost. However, while OMUS sensitivity has been reported in terms of noise equivalent pressure density (NEPD), there has been no comparison to conventional piezoelectric transducers under identical conditions. We differentially compared a highly sensitive ring-resonator-based OMUS and a single element focused piezoelectric ultrasound transducer (FPUT), under the same experimental conditions. The comparison considered the detectors’ signal-to-noise ratio (SNR), impulse response, axial point-spread-function and their spatial sensitivity. Our results show that OMUS attained lower SNR to FPUT, when operating at the same working distance, but similar performance when placed close to the sample interrogated, for example, as it relates to OptA microscopy. Advantageously, OMUS uniquely offers the spatial behavior of a point-like acoustic detector which reduces the sensitivity to ultrasound interference effects occurring on the large detection area of FPUTs. We discuss the implications of the two detection approaches in the design of OptA systems.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 18","pages":"34459-34467"},"PeriodicalIF":4.3,"publicationDate":"2025-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11121568","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145073262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given that photovoltaic (PV) modeling is regularly performed with subhourly time resolutions over multiyear periods, incorporating spectral effects can become challenging both in terms of file sizes and computational burden. For this reason, spectral irradiances are sometimes aggregated into a limited number of wavelength bands (or wavebands), such as the 32-band grouping known as Kato bands that is used in the IEC 61853 series of standards on “PV module performance testing and energy rating.” To test the impact of such aggregation, measured, and modeled spectral irradiance data from two sites in the United States—Tempe, Arizona and Golden, Colorado—are used to assess the impact on PV spectral effect estimates of aggregating spectral irradiances into Kato bands and into two other sets of wavebands known as PV-bands. Calculations using the aggregated spectra are compared with those using the full-resolution spectra, for crystalline silicon and cadmium telluride modules. Each of the three sets of wavebands yields negligible errors of less than 0.1% in the spectral derate factor, which characterizes long-term spectral effects. This indicates that both Kato bands and PV-bands should be sufficient for the purposes of PV energy rating. Meanwhile, a recent version of PV-bands performs best for evaluating the instantaneous spectral mismatch factor, leading to errors of less than 0.2% across all time steps for both sites and PV module technologies, while instantaneous errors for Kato bands reach magnitudes of up to 1.4%.","PeriodicalId":445,"journal":{"name":"IEEE Journal of Photovoltaics","volume":"15 5","pages":"657-661"},"PeriodicalIF":2.6,"publicationDate":"2025-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144887789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sensor binds to the target R. solanacearum deoxyribonucleic acid (DNA) selectively by functionalizing the electrode surface with a corresponding DNA probe. This results in detectable changes in impedance. The nonfaradaic method provides a strong and dependable method for pathogen detection by increasing sensitivity and reducing background noise. GCE can be used for biosensing applications because of its low background interference and compatibility with various biological experiments. We have already used a gold interdigitated electrode (IDE)-based method in our earlier investigation to detect R. solanacearum via DNA hybridization. In this study, C-MEMS-derived GCE is used, which offers a versatile, cost-effective, and stable alternative to gold IDEs, particularly in applications requiring high chemical stability, surface customizability, and cost efficiency.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 18","pages":"34348-34354"},"PeriodicalIF":4.3,"publicationDate":"2025-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145073208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The frequent start-up and braking of metro trains will aggravate rail wear, especially in the small-radius curved section of the line, which is more likely to produce a track irregularity state. To solve this problem, this article mainly proposes a new intelligent detection method for track irregularity. First, a new residual attention multistate gate control unit (RMGCU) is presented, featuring an innovative multistate hierarchical division mechanism in memory cells to improve the feature perception ability. Second, the elite opposition-based learning (EOBL) and Gaussian mutation strategy are introduced into the traditional Osprey optimization algorithm (OOA) to improve its performance, and the improved OOA is adopted to optimize the hyperparameters of CNN and RMGCU. Finally, a novel residual attention multistage spatial-temporal network (RAMSTN) is developed by fusing a CNN for multiband spatial feature extraction and RMGCU for enhanced temporal sequence modeling with hierarchical memory gating. The proposed RAMSTN effectively captures the spatial-temporal characteristics of vehicle body acceleration, enabling accurate end-to-end detection of vertical track irregularities. Experimental results demonstrate that the RAMSTN model achieves high accuracy in identifying the track irregularity value.
