In the vast expanse of oceanic shipping, the ship's engine serves as the core power source, bearing the crucial mission of propelling the giant vessel through the waves. Sensors, acting as the "nerve endings" and "sensory organs" of the engine, establish an inseparable symbiotic relationship with it through precise data collection and real-time feedback, becoming the vital support for ensuring navigation safety and enhancing operational efficiency.

With the rapid development of artificial intelligence and human-computer interaction technologies, tactile sensing technology, as a key tool for converting mechanical stimuli into readable signals, has garnered widespread attention.

Pressure resistant and waterproof acceleration sensors have become a "sensing tool" in extreme scenarios. This type of sensor achieves a dual breakthrough in protective performance and measurement accuracy through material innovation and structural optimization, providing a reliable solution for data acquisition in complex environments.

In nature, organisms have evolved a wide range of sensory abilities to survive. Among these, non-contact sensing—the ability to detect environmental changes and potential threats without direct physical contact—plays a crucial role in the survival strategies of many animals.

Flexible tactile sensors (FTS) are capable of sensing mechanical force signals such as strain, pressure, and shear forces, and are widely used in fields such as bionic prosthetics, health monitoring, artificial intelligence, and wearable devices. The ideal FTS needs to have both high sensitivity and high precision tactile signal detection capabilities. In practical applications, FTS is inevitably exposed to external interference environments such as mechanical shock, temperature and humidity changes. The complex interference generated by multiple stimuli can significantly affect the perception ability of FTS, thereby reducing its sensing accuracy. However, most existing FTS lack anti-interference capabilities, which can easily lead to perception errors or measurement distortions, greatly limiting their practical application scenarios. Therefore, developing FTS with simple structure, strong anti-interference ability, and high sensitivity has become an urgent need at present.

In the roaring workshop of gearboxes, early signs of bearing wear are often drowned out by ambient noise, leading to losses of hundreds of thousands of yuan by the time a failure erupts. The emergence of Senther Technology's 370AM1 stress wave sensor is transforming this predicament—it leverages its 38kHz high-frequency resonance characteristics to become a precise tool for detecting "suboptimal" signals in equipment.
