Nowadays, our world is moving to digitalization faster than all experts expected. Digitalization brings lots of solutions and also creates lots of problems. Digitalization has conquered our life. Different devices make our life simple. We use them as hobbies in our free time for gaming, reading, and other things. In case you are attracted to gambling check the online blackjack casino and test your luck! Science today can give us even our lost parts of bodies. 

Researchers have developed a cybernetic finger that can recognize materials when touched without damaging them. The device consists of sensors of different types and can automotive work and solve different tasks and check quality control.

Amazing Sensors

Touch sensors capable of acquiring information about surfacesю Such as pressure or temperature, are no longer new. But sensors that can recognize what kind of surface and its roughness. Also, they can recognize the surface which is pretty uncommon for people.

Dan Luo of the Beijing Institute of Nanoenergy and Nanosystems of the Chinese Academy of Sciences and colleagues have developed a finger that can determine what a material is made of. To do this, “triboelectric” sensors are used. They test the system on gaining or losing electrons and determine its roughness without damaging it.

The development was tested on many different samples. It was tested on wood, plastic, silicon, and other materials. the cooperation with data analysis based on machine learning, the best results of the finger’s accuracy of 96.8% and an accuracy of at least 90% for all materials.

How Does It Work?

There are four small square sensors in the device. Each is made from a different plastic polymer selected for its different electrical properties. When they are close to the object’s surface, the electrons from each square interact differently with the surface. And these features can be measured.

The sensors are hidden all in one finger. They are connected to a processor and an organic LED screen. This screen shows the details of the material. In industrial environments, the processor can be connected to the production control mechanism.

Smart fingers can help robots provide the check. If products meet manufacturing standards in terms of composition and surface texture they can increase the speed of checking time. This system can also play an important role in the sorting of industrial materials.

Robots can check products faster by using smart fingers.

If multiple tests prove that the design is reliable, the sensor’s ability to distinguish between materials could come in handy for tasks such as quality control in manufacturing, says Ben Ward-Cherrier of the University of Bristol, UK. However, an artificial finger will be most effective when combined with other sensors that can detect edges or friction.

Conclusion

In conclusion, today’s technologies can solve a lot of different problems. The main reason for not using them is the number of resources. Though, such a problem will be solved soon as well. The Chinese scientific world is amazing to us with its potential where robots can make operations on teeth and people can get another of their bodies. Science is changing our world. Interesting to keep observing it.
