Pressure sensors play a vital role in aerospace, automotive, medical, and consumer electronics. Although microelectromechanical system (MEMS)-based pressure have been widely used for decades, new trends sensors, including higher sensitivity, accuracy, better multifunctionality, smaller chip size, package recently emerged. The demand performance upgradation has led to breakthroughs sensor materials, design, fabrication, packaging methods, which emerged frequently recent decades. This paper...
The ocean contains abundant natural energy resources including several types of clean and renewable energy. Traditional harvesting (OEH) systems based on large electromagnetic generators have shown limitations inefficiency in irregular, low-frequency Triboelectric nanogenerators (TENG) emerged as a promising new source energy, it has significant technical advantages applying energy-efficient harvesting. self-driven system TENG been successfully used the Internet Things distributed sensor...
Laser heterodyne interferometry plays a crucial role in measuring the velocity of water particles during calibration hydrophones with optical method. The acts as an indicator acoustic-pressure variations and can be used to evaluate stability acoustic field. requires stable field environment; currently, though, assessment is largely subjective. This study introduces Normalized Dynamic Time-Warping (NDTW) algorithm, which objectively evaluates stability. Sine-fitting applied region interest...
Piezoelectric bimorph cantilever is a typical structure for vibration energy harvesting. This paper studies the method to improve accuracy of FEA (finite element analysis) simulation piezoelectric cantilever. The COSMOL methods based on 1 D (dimension) model Euler Bernoulli beam, as well 2 and 3 models solid mechanics are proposed respectively. Compared with theory experiment results given by Erturk A, influences material parameters in modeling discussed. error can be reduced less than 1.2%...
Abstract The development of excellently stretchable, highly mobile, and sustainable power supplies is great importance for self‐power wearable electronics. Transpiration‐driven hydrovoltaic generator (HPG) has been demonstrated to be a promising energy harvesting strategy with the advantages negative heat zero‐carbon emissions. Herein, this work demonstrates fiber‐based stretchable HPG high output, portability, knittability, generation. Based on functionalized micro‐nano water diffusion...
Aiming at the problem that path search rules in traditional planning methods are divorced from actual maneuverability of an unmanned surface vehicle (USV), a motion method state prediction rapidly exploring random tree (spRRT) is proposed. This retains discrete original RRT while adding continuity USV. Firstly, information for each movement (position, yaw angle, velocity, etc.), calculated based on mathematical model USV’s which takes into account complete dynamic constraints. Secondly, this...
We describe a single beam compact spin exchange relaxation free (SERF) magnetometer whose configuration is simple and compatible with the silicon-glass bonding micro-machining method. Due to small size of vapor cell utilized in miniature atomic magnetometer, wall could not be neglected. In this study we show that Ne buffer gas more efficient than other typically species such as nitrogen helium for reduction theoretically experimentally. 3 Amagats (1 Amagat=2.69×1019/cm3) filled first...
The chip-scale hybrid optical pumping spin-exchange relaxation-free (SERF) atomic magnetometer with a single-beam arrangement has prominent applications in biomagnetic measurements because of its outstanding features, including ultrahigh sensitivity, an enhanced signal-to-noise ratio, homogeneous spin polarization and much simpler configuration than other devices. In this work, miniaturized SERF based on microfabricated vapor cell is demonstrated. Although the optically thin Cs atoms are...
Atomic magnetometers, a prominent class of quantum sensors, have become increasingly significant in magnetometry, with extensive applications cutting-edge physics, biomedical imaging, industrial inspection, and beyond. However, the power consumption an atomic magnetometer is primarily dominated by that demanded to heat vapor cell its operating temperature. This temperature determines alkali-metal density, thereby influencing magnetic field sensitivity overall consumption, which poses...
The long-term sequelae of coronavirus disease 2019 (COVID-19) and its recovery have becoming significant public health concerns. Therefore, this study aimed to enhance the limited evidence regarding relationship between sleep quality on long COVID among older population aged 60 years or old. Our included 4,781 COVID-19 patients enrolled from April May 2023, based Peking University Health Cohort. Sleep was assessed using Pittsburgh Quality Index (PSQI) scale. Long evaluated by well-trained...
Ultraviolet B (UVB) irradiation alters multiple molecular pathways in the skin, thereby inducing skin photoaging. Murine dermal fibroblasts (MDFs) were subjected to a series of 4 sub-cytotoxic UVB doses (120 mJ/cm2), resulting changes cell shape, DNA damage, cycle arrest, extracellular matrix variations, reactive oxygen species (ROS) generation, and alterations major intracellular antioxidant cellular autophagy levels. Rapamycin (RAPA) is new macrolide immunosuppressive agent that primarily...
