Russia has created a material for biosensors and electronic skin

Specialists at the NTI Center "Digital Materials Science" at Bauman Moscow State Technical University have created a new hydrogel for biosensors - these are flexible sensors for health monitoring. They are used in a technology called electronic skin and create electrical signals in response to external influence.

In such systems, polymer hydrogels act as sensing elements. But due to their low mechanical strength and deterioration of performance due to swelling, they are often problematic in practical applications.

"To solve this problem, we have created an ultra-strong conductive self-healing polyurethane physical hydrogel with improved resistance to swelling based on a combination of a "flexible" block that imparts excellent hydrophobicity and flexibility, a "rigid" block that provides excellent mechanical properties due to the presence of a large number of reversible intermolecular hydrogen bonds, and a "conductive" block that provides electrically conductive properties," said a researcher at the Center for STI "Digital Materials Science: new

Regenerative materials, such as the prototype created by Russian scientists, open up new opportunities for creating devices that automatically restore their properties in case of damage and wear. This, in turn, significantly reduces operating costs and increases reliability.

But in order for the material to be used for implantation in the human body, it is necessary to conduct additional tests and prove its safety, says Daniil Arzhakov, a senior lecturer at Synergy University.
