Scientists have always been looking to build a computer than that can mimic human problem-solving abilities. Now, with thanks to Tae-Woo Lee and team from the Pohang University of Science and Technology in Korea, we may be one step closer to achieving that goal.
The human brain is a very complex machine that contains within it a system of around 100 billion neurons and one quadrillion connections linking them all together firing at around ten times per second. Although our brains are not quite as quick as some of the world’s fastest computers, they are very efficient in comparison hence why scientists want to mimic their capabilities into artificial synapses.
Artificial synapses, historically, have been quite poor in energy consumption compared to biological synapses, but the new ones act like more of a transistor and have the ability to switch on and off, therefore, using less energy. As part of the research, scientists assembled over 140 synaptic resistors to help improve the efficiency of them. The devices are made to mimic the work of biological synapses that occur in the human brain.
As research continues, scientists get more detailed in what they can do. As well as looking to reduce the already minuscule nanowires even smaller, they also feel they can reduce energy consumption further by altering the structure ad materials they are currently using. Scientists are also hoping to use 3D printers to create 3D grids of artificial synapses mimicking the whole of the human brain, but more advances are needed in the technology field before they can move forward with that one.
