Neuromorphic computing that mimics the human brain (opens in new tab) is one phase closer to reality as scientists from Washington Condition College have crafted a vital circuit for this new style of computing working with an unlikely pure material.
Employing bee-sourced honey, the scientists have constructed a evidence-of-concept memory resistor or memristor. To execute this feat, they 1st turned the honey into a good sort and then held it in between two metallic electrodes in a very similar way to how the brain’s synapses lay among pairs of neurons.
Adhering to its creation, Washington Condition University scientists analyzed the device’s capacity to speedily change on and off at speeds ranging involving 100 and 500 nanoseconds. The tests were being prosperous and the researchers hope that their new memristor can enable pave the way for biodegradable, sustainable and organic-based mostly computing methods going ahead.
In a press launch (opens in new tab) announcing the discovery, associate professor of WSU’s Faculty of Engineering and Personal computer Science, Feng Zhao furnished further more insight on honey’s probable in the development of mind-like personal computer chips, expressing:
“This is a really modest unit with a simple composition, but it has really identical functionalities to a human neuron. This indicates if we can combine thousands and thousands or billions of these honey memristors together, then they can be designed into a neuromorphic method that features a lot like a human mind.”
Neuromorphic computing
Typical laptop or computer programs like individuals discovered in business computer systems (opens in new tab) and cellular workstations (opens in new tab) are based mostly on the von Neumann architecture which involves an enter this sort of as a keyboard and mouse as nicely as an output like a monitor alongside with a CPU and RAM.

For occasion Fujitsu’s Fugaku (opens in new tab) supercomputer works by using 28 million watts in buy to operate even though the human mind uses only all-around 10 to 20 watts. This is why providers like Intel and IBM are doing the job on neuromorphic chips (opens in new tab) that mimic how the human mind features.
The human mind has more than 100bn neurons with extra than 1,000tn synapses or connections between them. As every neuron can each course of action and shop info, the mind is a great deal a lot more efficient than a regular laptop or computer.
At the similar time, typical personal computer chips (opens in new tab) are developed using nonrenewable and harmful products when neuromorphic chips, like the a single developed by researchers at Washington Condition College, can be built utilizing biodegradable resources as a substitute.
Going ahead, Zhao’s workforce aims to shrink the dimensions of its honey memristors from a microscale that is about the size of a human hair to a nanoscale which is about 1/1000 of a human hair. By doing so, the scientists will be in a position to bundle millions or even billions of honey memristors together to make a entire neuromorphic computing procedure.
