Discover how scientists from ITMO University and international partners have developed a groundbreaking organometallic material for neuromorphic processors, capable of storing data for over 200 days and revolutionizing machine learning applications.


Scientists from ITMO University, St. Petersburg State University, and Tongji University in China have made a groundbreaking advancement in neuromorphic technology by developing an innovative organometallic material. This new material is designed for neuromorphic processors and memory devices, showcasing an impressive ability to store data for over 200 days, significantly outperforming existing alternatives. The findings were reported by the Russian Science Foundation and published in the journal Communications Materials, highlighting the potential of this material in the rapidly evolving field of IT technologies.

Neuromorphic systems, which mimic the brain's functioning, are gaining traction in the tech industry. Unlike traditional devices that separate computing processors and memory, neuromorphic systems integrate these components into a single block. This unique architecture enables the simultaneous execution of complex calculations while consuming minimal power. However, the development of these systems necessitates new materials that possess distinct physical properties compared to conventional silicon-based processors.

The newly developed organometallic material consists of a crystal formed from a porous polymer matrix infused with water and copper molecules. When exposed to laser stimulation, these molecules temporarily detach from the crystal's inner surface, altering its electronic properties in a manner reminiscent of how nerve cells respond to external chemical stimuli. By utilizing laser and electrical pulses, akin to the binary coding of standard computers, researchers successfully modified the crystal's state to 'write' information onto it.

Through comprehensive chemical and physical experiments, the team confirmed that data stored within this medium could remain intact for up to 200 days, far exceeding the longevity of most neuromorphic materials currently available. Additionally, the researchers constructed a computer model of a neural network, training it with 60,000 images to achieve a perfect recognition accuracy of 100% in identifying handwritten text. This simulation, although not yet implemented in a physical device, demonstrates the organometallic compound's substantial potential for machine learning applications.

Project leader Valentin Milichko, a Doctor of Physical and Mathematical Sciences and leading researcher at ITMO University, emphasized that while the current findings are based on simulations, they pave the way for the future creation of a real neuromorphic network utilizing these innovative crystals.

  • The development of neuromorphic systems is crucial as they promise to revolutionize how machines process information, leading to faster and more efficient computing capabilities. The integration of memory and processing functions into a single unit allows for more streamlined operations, which is particularly beneficial in areas requiring rapid data analysis and decision-making.
  • The significance of this research extends beyond mere data storage; it presents a potential shift in how artificial intelligence (AI) and machine learning systems can be designed. By mimicking the brain's neural processes, these systems can become more adaptable and efficient, opening new avenues for technological advancements in various fields such as robotics, autonomous systems, and complex data analysis.
