Utrecht and Sogang Universities are building an artificial synapse that works with water and salt and can process complex information, just like our brain.

A new study published in the journal Proceedings of the National Academy of Sciences shows that a system that works with water and salt can process complex information in the same way as our brains. This is an important milestone in the development of more authentic brain emulation computers.


The artificial synapse that the researchers have developed is based on a small device that mimics the behavior of a natural synapse. This device works using a solution of water and salt and can change its conductivity based on electrical impulses. Furthermore, the study shows that the length of the device can affect the time it takes for concentration changes to disappear.

This opens up the possibility of customizing the device's length so that it can retain and process information for different time periods, just like natural synapses in our brains. Tim Kamsma, a PhD student at the Institute for Theoretical Physics and the Mathematical Institute of Utrecht University, and the lead author of the study, is excited about the results.


He says, "While artificial synapses that can process complex information already exist based on solid materials, we now show for the first time that this can be achieved using water and salt. We effectively recreate neuronal behavior using the same medium like the brain."

This study opens the door to new possibilities in iontronic neuromorphic computing - a field that focuses on building computers that work with the same medium as our brains. By adopting a more authentic approach to brain emulation, we may someday be able to build computers capable of replicating the extraordinary abilities of our own minds.
