New high-tech glove makes dentures more sensitive

Today for people with disabilitiesscientists and engineers have developed a huge number of a wide variety of gadgets. Among them are prostheses of limbs. Moreover, these prostheses are quite functional and can perform a huge number of different actions. But an important drawback of almost all such devices is that they cannot return sensitivity to a person. However, a certain step in front of this is the new high-tech glove. Moreover, it can be combined with existing prostheses, which significantly reduces the cost of production and makes the gadget more affordable.

The new glove is one of the most affordable ways to restore sensory sensitivity to a person. At least partially

How does the glove work to regain sensitivity?

The development team is responsibleengineers from Purdue University, the University of Georgia, and the University of Texas. The new glove in appearance, we can say, does not differ from ordinary products of this kind. It can be easily put on almost any existing prosthetic hand to give them the opportunity to feel various parameters. The glove is designed to improve the user's ability to interact with other objects.

A number of elastic gloves are integrated into the innovative glove.sensors and flexible sensors that can measure pressure, temperature and hydration (i.e. moisture) of everything that the material comes into contact with. At the same time, you should not think that the glove will allow you to feel all this directly. It would be too expensive and similar technologies would not allow to make the device affordable.

We used our approach to how to equipany prostheses, including those existing on the market. The material and sensors used in the manufacture of the glove allow it to be used with prosthetics of various shapes and sizes, ”said Purdue University associate professor and lead author of the work, Chi Hwan Lee. On the one hand, the glove allows the user to understand the properties of surrounding objects, and on the other hand makes the prosthesis more realistic.

As for how the glove givesthe user the opportunity to know about the properties of the subject, everything is quite simple: the characteristics are transmitted to the smart watch connected to the device. This watch processes all the information received in real time. The developers consider this approach the most appropriate from the point of view of the final cost of the glove. In addition, the glove is equipped with the ability to transfer data about the characteristics of objects to a separate device for processing and analysis.

Also, when shaking the watch gloves, you canGet information about the device like battery and sensors. Such functionality, although it does not return sensitivity in the full sense of the word, allows a person to understand the properties of objects. For example, how fragile or hot an item is, by manipulating, for example, a paper cup with tea, the user will immediately understand whether the tea is hot and what force to apply in order to correctly squeeze the cup in his hand.

It is also worth noting that in the future, developersThey plan to equip the glove with a tactile feedback system and vibration motors for a more accurate and complete transfer of sensations from touching various objects. The possibility of using the technologies used in the manufacture of gloves to create other types of prostheses is not ruled out. For example, giving sensitivity not only to artificial brushes, but to the whole arm as a whole. You can learn more about the smart glove device using the video available below.
