n the field of modern precision measurement and automation control, micro eddy current displacement sensors have become indispensable key components due to their unique technological advantages. This sensor is based on the eddy current effect and can achieve non-contact high-precision displacement measurement, playing an important role in many fields such as industrial production, scientific research, aerospace, etc.

Implantable deep brain probes (DBPs) are an important component of brain computer interfaces that facilitate direct interaction between neural tissue and the external environment. Currently, most multifunctional DBPs used for sensing and regulating the nervous system are manufactured through thermal gradient reduction of polymer materials. However, this method still faces challenges such as how to choose materials that can adapt to the thermal stretching process and match the modulus of brain tissue.

In today's era of rapid technological development, industrial production is undergoing unprecedented changes. From traditional human driven to today's intelligent and automated production, industrial sensors play a crucial role and bring many significant benefits to the industrial field.

Proton conductors based on Grotthuss jump mechanism have unique advantages in the field of deformation sensing. Unlike traditional deformation sensing electrolytes that rely on the diffusion and migration of loaded ions such as metal ions or ionic liquids, the Grotthuss mechanism achieves proton conduction through continuous reconstruction of hydrogen bonding networks, significantly reducing the energy barrier for proton migration.

Ultra low temperature vibration sensor, designed based on principles such as piezoelectric effect and magneto electric induction, can accurately convert vibration signals in ultra-low temperature environments into electrical signals. The core sensitive components are usually made of special materials, such as certain piezoelectric crystals, which can maintain good physical properties at ultra-low temperatures, providing a basis for accurate signal perception. For example, in extreme low temperatures of -269 ℃, some ultra-low temperature vibration sensors can still work stably, demonstrating strong environmental adaptability.

In the current wave of industrial intelligence, industrial sensors, as key components for obtaining information, play a crucial role like the "nerve endings" of industrial systems. It is not only the cornerstone of industrial automation and intelligence, but also the core force driving the development of Industry 4.0.
