However, inorganic materials such as silicon are generally stiffer, while human skin is softer and malleable. All, the application of electronic circuits made of silicon materials to human skin is not the best solution. As a result, scientists have turned their attention to organic materials, such as special plastics or carbon-based products such as graphene as the basis for electronic skin.
In general, a typical electronic skin consists of different electronic components—flexible transistors, organic LEDs, sensors, and organic solar cells—that are connected together using extensible, flexible conductive cables to form an electronic skin.
It is understood that these devices are usually constructed of very thin materials that are sprayed onto a flexible substrate to form a large area of ​​skin-like electronic circuitry.
In the past few years, driven by robots, this technology has developed rapidly because people want to give your robots a human-like perception.
We now have electronic skin devices that detect object objects, measure temperature and sense pressure, allowing robots to work more flexibly and safely. If these electronic skins are combined with wearable technology, it can ensure that the human body is safer to perform activities, such as Some unsafe movements were detected during exercise.
In addition, this technology creates opportunities for the emergence of flexible screens, and now at least one company is developing technology that uses sensors and projectors to turn human skin into a touch screen.
But one day, will we really apply this technology directly to the body, and to what extent will it be popular?
The problem is that current organic electronic component technology is not mature enough and reliable, and performance is insufficient. Furthermore, the atomic structure in organic materials is more confusing than the atomic structure in inorganic materials. In organic materials, electrons are 1000 times slower than inorganic materials.
Biocompatibility is also important. How to integrate electronic skin into the human body and ensure that it does not have any impact on human health and safety is a problem that needs to be solved.
Organic materials based on carbon are generally more biocompatible and will not be rejected by the human body. However, the carbon particles themselves are relatively easy to pass through the cells, which causes inflammation and causes the body to produce an immune response.
If these problems are resolved, in the future, we are expected to see electronic skins replace current wearables, such as smart watches or fitness bracelets. Just don't know, are you willing to implant permanent or semi-permanent electronic skin circuits into your body?
