Magnetic artificial skin could bring super powers to humans
A magnetic skin that is safe and comfortable to use can open the door to a wide range of wireless and remotely controlled applications. Who has never freed Jedi from within and used “force” to open automatic doors in the mall? Take it easy, save the lightsaber, let's talk about a technology that will give you super powers.
A new magnetic skin has been developed that can remotely control switches and keyboards with the wave of a hand or the blink of an eye.
Artificial skin that gives "super powers"
Artificial leather is wearable, flexible, light and magnetized, making it useful in a variety of applications without the need for a wired connection to other devices.
Artificial electronic skins typically require a power supply and data storage or communication network. However, this involves batteries, wires, electronic chips and antennas and makes the skins inconvenient to wear. Our magnetic skin doesn't require any of that. As far as we know, it's the first of its kind.
Explained electrical engineer Jurgen Kosel, who led the project.
The film is made of an ultra-flexible and biocompatible polymer matrix filled with magnetized microparticles.
The skin can be customized in any shape and color, making it imperceptible and even elegant. Moreover, the manufacturing process is cheap and simple. Anyone can start their own artificial skin project after a few minutes of training if they have the tools and materials.
Magnetic skin that dresses to control devices remotely
The team tested the magnetic skin to monitor eye movements. Thus, this film was glued to an eyelid with a nearby multi-axis magnetic sensor. Eye movement altered the magnetic field detected by the sensor when the eyelid was opened or closed.
The sensor can be incorporated into eyeglass frames or a sleep mask. In addition, it can also be applied as an electronic forehead tattoo. It has the potential to be used as a human-computer interface for people with paralysis or for games; to analyze sleep patterns; or to monitor eye conditions such as eyelid drooping or driver alert.
Subsequently, the team also attached the skin to the fingertip of a latex glove and placed a sensor inside a light switch. As the magnetic skin approaches the sensor - a distance that can be modified - the light goes on or off. This application may be especially relevant in laboratories and medical practices where contamination is a concern.
Kosel and his team are now extending the application so that this technology can be used in a gesture-controlled wheelchair. In addition, this technology, which acts as a contactless human-computer interface, could be used on non-invasive biomedical devices.
