Ultrasonic measurement techniques are increasingly used to measure the burning rates of solid rocket fuel, but challenges arise due noise and signal attenuation caused by motor’s multi-layered structure. This paper proposes an adaptive thresholding method combined with a wavelet threshold function for effective ultrasonic denoising. Additionally, extreme value feature fitting algorithm is introduced accurate echo localization, even in low signal-to-noise ratio (SNR) conditions. Numerical...
In this study, flexible thermoelectric tin selenide (SnSe)/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) composite films have been fabricated by the vacuum filtration method, and their properties were investigated. The electrical conductivities of a tendency to decrease with an increase in SnSe content, while Seebeck coefficients inverse tendency. gradually temperature, show first then temperature. maximum power factor (PF = S 2 σ) film is obtained when content 10 wt%,...
With the development of society and advancement technology, emergence Internet Things (IoT) has changed people's lifestyles raised demand for energy to a new level. However, there are some drawbacks in terms supply IoT sensors, such as limited battery capacity limitations replacement maintenance. Therefore, it become urgent develop sustainable green source (wind energy) using surrounding environment. Meanwhile, triboelectric nanogenerators (TENGs) with advantages flexible structure, low...
In the resonator micro-optic gyro (RMOG) frequency locking loop, digital-to-analog converter quantization error leads to low-accuracy laser tuning, causing and rotation sensing dead zones. This paper proposes a planar waveguide (PWR) scheme with piezoelectric (PZT) ring tune PWR resonant track lock frequency. The proposed achieved PZT-PWR Q = 4 × 107 tuning coefficient 1.124 MHz / V. Direct comparison on an RMOG device experimentally verified reduced noise 0.25 deg s improved resolution from...
Triboelectric nanogenerators (TENGs) are effective for harvesting mechanical energy and converting into electricity. Such devices have high output voltage low current, appearing as impedance. Impedance mismatches involving these create challenges in power usage, storage, management. Herein, a dual‐tip‐assisted TENG is developed its electrical performance under airtight condition investigated. The generated charges can rapidly accumulate at the dual tip produce potential difference....
With the advantages of fast, real-time, multi-element detection and little or no sample pretreatment, laser-induced breakdown spectroscopy (LIBS) technology has a broad range applications in seafloor hydrothermal chimneys mineral resource exploration. However, most analyses are still mainly dependent on laboratory tests after sampling. Underwater LIBS suffers from low sensitivity poor stability due to attenuation laser energy by water confinement quenching effects plasma. For long-time...
As a vibration signal acquisition device, the sensor has important application prospects in aerospace, industrial manufacturing, and other fields. The traditional electrical is limited by its material sensitive mechanism some bottleneck problems, such as poor anti-electromagnetic interference ability, temperature resistance, inability to self-calibrate. Here, we report high-temperature self-calibration fiber-optic based on an atomic frequency standard system for first time. absolute...
The rigid Fabry-Pérot (F-P) cavity has emerged as the preferred core sensing component for optical pressure, vibration, and acoustic in harsh environments, owing to its high reliability structural stability. However, due inadequate temperature resistance of dielectric film, maintaining a level precision F-P at elevated temperatures proves be challenging. Volume Bragg grating (VBG) is three-dimensional element modified by femtosecond laser within transparent glass medium create periodic...
