Researchers have created a bio-inspired skin made from an ionic polymer that can sense pressure, humidity and temperature changes of even 0.1 degrees. When the material suffers mechanical damage, it fully restores its integrity in just 30 minutes, and in a water environment at that, which is a serious problem for many similar materials.
These properties make the material a serious candidate for underwater research robots, which often operate in humid and aggressive environments where conventional sensors quickly fail. In addition, the innovation is planned for use in next-generation bionic prostheses, where not only sensitivity but also the durability and self-healing ability of the material are important.
Perhaps the most interesting detail here is not the self-healing itself, but how small a fluctuation the material can sense — 0.1 degrees. This is already a serious requirement for biomedical applications as well, where the precision of sensors often determines the usefulness of the entire device.
On the other hand, a laboratory result does not yet mean that the material will work just as well in real conditions — in salt water, under pressure or during prolonged use. It is precisely this field-testing phase that will show whether this is a serious technology or still just an interesting scientific result.
