Chinese scientists have created a fully hydrophobic ionogel. It uses highly efficient underwater sensors and communicators even underwater.
A team of scientists led by Professor Chen Tao of the Chinese Academy of Sciences (CAS) has developed a fully hydrophobic ionogel. It allows the use of highly efficient hand-held underwater sensors and communicators underwater. The research was published in the journal Materials Horizons.
Wearable underwater sensing technology is indispensable for subsea operations – marine exploration, subsea construction, rescue and more. To make it more accessible, Chinese scientists have created an ion-conducting gel. They optimized the material that worked maximum in wet conditions, but not under water.
In the course of experiments, the scientists showed ionogel long-term stability. Its good hydrophobic properties increased its adhesion in the underwater environment due to the destruction of the hydration layer. Also, scientists have found that the ionogel does not interfere with the operation of equipment, has a wide deformation range and excellent sensitivity and durability. It accurately detects human and aquatic body movements in complex underwater environments, demonstrating the potential for biological research applications.
