In a development that could change the landscape of computer technology, Utrecht University from the Netherlands and Sogang University in South Korea have jointly announced results in the development of artificial synapses. Their research, showcased in a recent article on Phys.org, presents the first experimental proof that a system utilizing water and salt, resembling a similar process in comparison to the human brain, can effectively process complex information. This has monumental implications for the field of neuromorphic computing, as it could lead to the creation of systems more aligned with the natural processes of the brain. This shared medium uses ion transport to replicate the behavior of biological synapses, paving the way for a new horizon in artificial intelligence and information processing.
Is brain-like computing bridging the computational divide?
At the heart of this brain-like computing discovery is the fundamental difference in the way traditional computers and human brains work. While conventional computers operate using on/off binary logic gates, the human brain’s neurons communicate through a complex interplay of ion channels. The brain’s reliance on water and salt, simple wet-dry ionic systems, has now inspired an innovation that could serve as a bridge between artificial and biological intelligence.

This approach capitalizes on what Tim Kamsma, lead author of the study and a Ph.D. candidate at Utrecht University, describes as “analog” rather than binary processes. Analog computing models continuous changes in contrast to digital methods that register discrete changes. By designing ion channels that mimic these processes, Kamsma and his colleagues have demonstrated how these ‘watery’ synapses can process real-world-like information, potentially creating computers that can learn and adapt in ways that are currently beyond the capabilities of binary-based systems.
The science behind the feat of brain-like computing
The groundbreaking aspect of this project lies in the complexity of the information being processed. While previous iterations of artificial synapses have existed, they paled in comparison to the flexibility and adaptability of biological synapses. These new artificial synapses, laden with water and salt, offer a remarkable configuration. This design choice creates a system capable of storing and processing information for variable durations, an essential aspect of neural networks’ ability to learn and evolve.
In order to achieve this feat, the team engineered a unique set of ion channels that behave like their natural counterparts. Through precise manipulation, the researchers developed channels capable of both information storage and timed release functioning in synchronicity with a biologically inspired effort to underpin more sophisticated computing. With this achievement, Kamsma and his international team are leading the charge toward a future of iontronic neuromorphic computing, a realm where computers not only mimic but also extend the capabilities of the human brain.
Pondering the future of computing
The landmark success of Utrecht and Sogang universities brings to the fore an age-old question in computing: digital or analog? Could the future of computation lie in systems that bear a closer resemblance to the organic processes of life? The prospect of neuromorphic computing, achieved through ion-based systems, beckons a deeper understanding of the human mind’s operation, potentially leading to a paradigm shift in AI. Furthermore, it hints at a more profound philosophical inquiry of not just creating devices that imitate human cognition but actually designing systems that share in its fundamental mechanisms. It’s too early to surmise that iontronic neuromorphic computing will supplant traditional methods, but the research unequivocally marks a significant step forward in the pursuit of genuinely intelligent machines and, perhaps, a world where machines and brains converge in their essence.

Brain-like computing or iontronic neuromorphic computing could emerge as an alternative or an improvement over traditional computing. How might they compete with the future technology of quantum computing? The work of Utrecht and Sogang universities exemplifies a meticulous blend of theoretical propositions and experimental validations, and their contribution to the field could galvanize a technological revolution. While the road ahead is uncertain, one thing is clear: the news from these institutions is stirring, and it portends a future that could be as ingenious as it is enigmatic. We might be witnessing the first surges of a digital tide that could reshape the computational shorelines.
