NEW DELHI: IIT Madras has successfully invented a technology based on the phenomenon of AI or Artificial Intelligence which can specialise in transforming brain signals into the English language in the near future. It is specially designed for speech-impaired individuals. It can also be used to comprehend the signals sent by the nature like photosynthesis in plants or it's reaction to any outer stimulus.

A research team that was guided by Dr. Vishal Nandigana, Assistant Professor in Mechanical Engineering carried out this project.

He emphasised upon the research and said, "The output result is the ionic current, which represents the flow of ions which are charged particles. These electrically driven ionic current signals are working on to be interpreted as human language meaning speech. This would tell us what the ions are trying to communicate with us. When we succeed with this effort, we will get electrophysiological data from the neurologists to get brain signals of speech impaired humans to know what they are trying to communicate."

Revolutionary scientists like Issac Newton, Joseph Fourier and Jean-Baptiste are responsible for discovering physical laws and mathematical transforms. Signals which are electrical or from the brain or so on are in the form of a wave that can be decoded into meaningful data by using the aforementioned laws and transforms.

 Prof. Nandigana further elaborated, "The other major application of this field of research we see potentially is, we can interpret nature's signals, like plant photosynthesis process or their response to external forces mean when we collect their real data signal. The data signal also, we believe, is going to be in some wave-like pattern with spikes, humps and crusts. So the big breakthrough will be can we interpret what plants and nature are trying to communicate to us. This will help in predicting monsoons, earthquakes, floods, Tsunami and other natural disasters using our Artificial Intelligence and Deep Learning algorithms. If we understand the nature signals well we can take care of it well which is our objective that we want to pitch in from our laboratory,"

As of now, the team is trying to discover whether it is possible to transform the raw data. It will further be working on a way to convert the signals in the form of real data into any human language like English. 

The concept was tested in such a way that it required experimental electrical signals by experiments in the lab to get signals from the nanofluidic transport inside the nanopores. Nanopores are nanometer scale holes which are created though a natural phenomenon in protein and cells. These pores contained saline solution and got mediated by an electric field.
