New sensors for electronic skin devices provide new senses

OFweek Medical Technology Network Beijing time on February 6th news, according to foreign media reports, when traveling around the world, the need to use more than just five human functions. Indeed, our five faculties are impressive enough, but we lack the ability to feel the magnetic field.

Many creatures have this ability, such as sharks, birds and insects. Therefore, they can point themselves to the magnetic field by sensing the magnetic field, including determining the actual position, altitude and direction. For humans, this will be an extremely useful skill.

We can get the sensor by implanting it in the body or by wearing it on the body. The new equipment, led by Dr Denys Makarov, is led by the Leibniz Institute for Solid State and Materials Research and the Chemnitz University of Technology ( Researchers at TU Chemnitz, the University of Tokyo, and Osaka University have collaborated.

However, this feature is not the only unique feature of the device. It is light and flexible, easy to fit on the skin, even if it is bent and folded, it will not damage its function.

The sensor is less than 2 microns thick and weighs only 3 grams per square meter, so even if it is placed on a soap bubble, the soap bubbles will not be crushed by it. It can also withstand strong folding, and the radius can be compressed to within 3 microns, as if it were smashed into a bundle of waste paper.

In addition, the device can be stretched by 270%, even if you repeatedly stretch more than 1000 times, it will not break due to material fatigue. We all know that the movement of the human palm is very frequent, and the device can only be successfully applied to the palm of the hand if it has such characteristics.

"(This kind of sensor) is like... a sensitive skin, you can hardly notice its existence, but you can have the ability to feel the magnetic field, navigate for you, and achieve touchless operation." Written in the summary.

“These extremely thin magnetic field sensors can be used in a variety of applications, such as human skin, while providing 'new senses' for robotics, safety and medical monitoring equipment, consumer electronics and electronic skin equipment.”

Currently, the sensor does not provide tactile feedback to the user, but instead conveys information through a series of LED lights. When the user brings the sensor close to the magnetic field, the LED light illuminates to indicate that the sensor is running. Although this is inconvenient for the daily use of humans, it is an ideal way for robots.

"If you can combine magnetic field electronics with other lightweight and practical components, such as solar cells, light-emitting diodes, transistors, and temperature and touch sensors, you will have a variety of 'sensory' and become more autonomous and intelligent. Turn."

Researchers hope that their work will inspire more workers and create more equipment that will allow humans to further benefit from the “sixth sense” – the magnetic field.
