As the core supporting component of large rotating machinery such as steam turbines, water turbines, and compressors, the operating status of sliding bearings directly determines the safety and stability of the equipment. The oil film between the bearing and the journal is the key to ensuring the smooth operation of the bearing. The rationality of the oil film clearance directly affects the lubrication effect, friction loss, and equipment life.

Flexible strain sensors can convert mechanical deformation into electrical signals and play a central role in emerging applications such as medical monitoring, electronic skin, and soft robotics. In recent years, breakthroughs in sensing layer engineering have led to the development of stretchable sensors capable of withstanding ultra-large tensile strains (>400%) and compressive sensors functional under extreme compression (>80%).

In the field of condition monitoring and fault diagnosis for rotating machinery, order tracking technology has become a core solution for addressing the challenge of fault identification under variable-speed operating conditions, owing to its precise analysis capabilities for non-stationary signals. As the "sensing terminal" for signal acquisition, the selection and application of sensors directly determine the accuracy and effectiveness of order tracking. The deep integration of these two technologies provides reliable support for the health management of rotating machinery, widely applied in critical sectors such as aerospace, rail transit, and industrial manufacturing.

Achieving highly sensitive and specific detection of human IgG and glucose is of great significance for early disease diagnosis and efficacy evaluation. Although traditional methods such as ELISA and PCR are sensitive and reliable, their complex operation and high costs make them difficult to meet the needs of on-site rapid testing.

X disease is a term coined by the World Health Organization (WHO) in 2018 to refer to a newly emerging pathogen or a previously known pathogen with newly acquired pandemic potential (Simpson et al., 2020).

In the fields of infrastructure safety monitoring, seismic detection, and large-scale structural health management, ultra-low-frequency, low-noise, and high-stability acceleration sensing is the core to ensuring reliable data and timely warnings. Based on the mature 374A series,Senther has introduced an optimized and updated version of the seismic acceleration sensor, achieving comprehensive upgrades in noise control, low-frequency response, and temperature adaptation.
