Water droplets can power the future computers or will have an impact in the computing world according to the study conducted by Aalto University in Finland.
According to the study which was published in the Journal Advanced materials, they have developed a new concept in computing, using water droplets as bits of digital information.
The project describing the superhydrophobic was logic was enabled by the discovery that upon collision with each other on a highly water-repellent surface, two water droplets rebound like billiard balls.
The researchers experimentally determined the conditions for rebounding of water droplets moving on a superhydrophobic surfaces.
In the study a copper surface coated with silver and chemically modified with a flourinated compound was used, to enable the surface to be so water-repellant that water droplets roll off when the surface is tilted heavily.
The researchers also stated that they have presented elementary Boolean logic operations and a flip-flop memory based on rebounding water droplet collision.
Although the researchers admitted that not everything will be running on water droplets in the near future but they optimistic that the water droplets powered computing could be used in specialized systems that don’t have access to electrical power supply.
The main purpose of the project is to turn the water droplets into digital bits – the basic unit of transfer data.
