An international team of physicists from the Netherlands and South Korea has created, for the first time, an artificial synapse that transmits information in the same way as the human brain. The research was published in the scientific journal magazine Proceedings of the National Academy of Sciences (PNAS).
Computing systems based on the physical principles of the human brain attract the attention of scientists and engineers due to their high energy efficiency. The brain consumes approximately 10 times less energy than an average computer.
Previous experiments had led to the development of computers that mimic brain activity but use commonly used solid materials. Our brain uses water and salt ions as a medium.
In the new study, the team created a 150 x 200 micrometer neuron analog that transmits information using ions in an aqueous solution.
The new device was called the ion memristor. When electric pulses are received, ions in the liquid pass through the channel, causing the ion concentration to change.
Depending on the intensity or duration of the impulse, the conductance of the channel adjusts accordingly, reflecting the strengthening or weakening of connections between neurons. The degree of change in conductivity serves as a measurable representation of the input signal.
According to the authors of the study, their discovery could form the basis of new computer systems that are significantly superior to modern technologies in terms of efficiency and energy consumption.
