This material, which is used in robotics, has the ability to regenerate itself.


Because of what they entail, technological advancements can be overwhelming to people. And some can leave more than one person speechless at the thought that humans are capable of doing so.

According to the study published in Nature, several researchers at the University of Cambridge have developed self-healing, biodegradable, 3D-printed materials that could be used in artificial hands or other soft robotics applications.

This technology has the potential to revolutionize robotics. Not only that, but Tactile devices may also evolve as a result of this breakthrough. So far, most soft sensing technologies have been short-lived and energy-intensive.

"Incorporating soft sensors into robotics allows us to get a lot more information from them," said David Hardman, the study's lead author from Cambridge's Department of Engineering. "It's similar to how muscle tension allows our brain to receive information about the state of our body."

This team of researchers created gel-like materials that can detect tension, temperature, and humidity. One of the advantages of these robots over previous generations is their ability to repair themselves partially at room temperature.

Previously, robots required heat to repair themselves, but the researchers wanted to change that so that the technology could be commercialized.

"We began with an elastic material based on gelatin, which is inexpensive, biodegradable, and biocompatible, and we performed various tests on how to incorporate sensors into the material by adding numerous conductive components," Hardman explained.

Several tests were carried out by the researchers. They discovered that printing the sensors with sodium chloride, also known as salt, rather than carbon ink, resulted in a material with the desired properties.

Because of their low cost and ease of fabrication, self-healing materials are the best choice in robotics for making soft sensors. They are still a concept, but if further developed, they could be used to create artificial skins, among other things.
