[ Hot attention of chemical machinery equipment network ] The lateral line is an important source of fish's sensitive perception ability.
It is because of the existence of the lateral line that fish can accurately judge the changes of surrounding water currents, reefs, natural enemies, etc.
, so as to avoid damage
.
If this capability can be applied to the sensor field, it will greatly promote the development of underwater detection technology

If this capability can be applied to the sensor field, it will greatly promote the development of underwater detection technology
.
In recent years, underwater sensors have been released, most of which are made of flexible sensing materials
.
However, the surging water and the complex underwater environment inevitably interfere and destroy the sensing performance of the sensor, resulting in a shallow detection range, and the underwater detection technology has not been able to make great progress
.
Therefore, an underwater sensor that accurately captures underwater depth and vibration and is anti-interference is urgently needed to provide excellent equipment support for underwater detection

Recently, researcher Chen Tao and associate researcher Xiao Peng of Ningbo Institute of Materials Technology and Engineering, Chinese Academy of Sciences have developed a fish-like lateral underwater mechanical sensor based on graphene/Ecoflex film.
The size of the supporting composite film realizes underwater detection, and the depth can reach 0.
3-1.
8 meters
.
This is undoubtedly a "long-awaited start" for relevant researchers
