Engineers created the first printed transistor that decomposes in the water


Researchers have created the world-printed transistor in the world, which can be divided into source components with water and sound waves for reuse.

Most of the failed electronics are not processed due to the complexity of separation and restoration of valuable materials. However, now scientists from the University of Duke found a way of making printed chip from biodegradable materials.

As the basis, engineers used ordinary paper on which three types of ink applied to get a fully carbon transistor. Conductive inks from graphene, semiconductor carbon nanotubes and developed by the dielectric ink from nanocellulose were applied using inkjet printing at room temperature.

During the six-month tests created by such technology, the sensor worked quite well and remained stable.

To separate the elements of the printed chip on the source elements, it is sufficient to immerse it into the water and create vibration with sound waves. Subsequent treatment on the centrifuge allows you to extract almost 100% nanotubes and graphene, which can be reused in ink for printing.

According to the engineers themselves, in the near future, the technology will not be able to replace modern methods for the production of computer processors, but can lay the foundation for a new type of electronics.

Recall that earlier engineers also developed transistors fully consistent
