It's no secret that many modern technologies are based on the use of various biological natural principles – this is why the talented team of biological engineering from the University of Queensland today presented the results of a new study on the possibility of using human hair as the basis for creating LED displays. Moreover, their development is something really interesting and promising in terms of creating really high-quality LED displays for a certain number of mobile and portable equipment, which is a really great moment.
Human hair contains carbon and nitrogen, both of which are very effective chemicals for creating particles that emit light and are themselves photosensitive. It is these particles that are the basis of LED-screens, because through the allocation of blue light they allow you to manipulate the color palette of the emitted light. As for the procedure for the preparation and use of hair as the basis for such screens, then specialists first specially treated human hair, mainly taken from local barbershops, and then burned them at a temperature of 240 degrees Celsius.
After that, from the created points with a carbon and nitrogen content, scientists designed something like islands with a diameter of less than 10 nm, and these same points also play the role of nanodots-LEDs that emit blue light and allow you to adjust the palette. However, according to preliminary results of testing such a project, scientists noted that their development does not allow making excessively bright and large screens, due to the low brightness of the nanodots.
On the other hand, this approach allows you to create something really interesting for portable and small devices, since there is no need to further increase the degree of brightness of the nanodots. All that remains is the question of how quickly and how efficiently developers can optimize their chemical process of transforming hair into carbon nanodots, because the degree of their implementation in science will depend on this.
