Harnessing billions of years of evolutionary R&D to create the next generation of computing technology
Imagine if we could harness the computational power of the human brain—a marvel of evolution that operates on just 20 watts of energy, yet outperforms supercomputers requiring millions of watts for certain tasks. This tantalizing possibility is driving one of the most exciting frontiers in modern technology: bioinspired computation.
By looking to biological systems—from the neural networks in our brains to the collective intelligence of ant colonies—researchers are fundamentally reimagining how we process information. These approaches are not merely copying nature, but rather extracting design principles refined over billions of years of evolution to solve complex problems with stunning efficiency 9 .
The timing couldn't be more critical. As we approach the physical limits of silicon-based computing and grapple with the enormous energy demands of modern AI systems, bioinspired approaches offer a path forward that is both more efficient and more powerful.
Bioinspired systems operate on a fraction of the energy required by traditional computing architectures.
Inspired by natural systems, these technologies can adapt to changing conditions and recover from failures.
The Foundation of Bioinspired Computation
Among the most established bioinspired approaches are evolutionary algorithms, which apply the principles of natural selection to optimize solutions. These algorithms create a population of potential solutions to a problem and then subject them to processes of selection, crossover (recombination), and mutation 6 8 .
Recent advances have produced sophisticated variants like the Enhanced Greylag Goose Optimization Algorithm (EGGO) which incorporates dynamic strategy adjustment from evolutionary game theory 6 .
While artificial neural networks have been used for decades in software-based AI, a new frontier is emerging in neuromorphic hardware—chips designed to physically mimic the brain's architecture 5 .
This approach is particularly evident in recent work with 2D materials, which have exceptional properties for next-generation neuromorphic devices. Their atomic-scale thickness, tunable physical properties, and superior integration compatibility make them ideal candidates 5 .
Swarm intelligence draws inspiration from the collective behavior of decentralized systems found in nature, such as ant colonies, bird flocks, and fish schools.
Recent research has advanced this concept through algorithms like the Novel Greylag Goose Optimization Algorithm with Evolutionary Game Theory, which improves upon traditional swarm intelligence approaches by incorporating dynamic strategy adjustment 6 .
Unlike traditional von Neumann computers with separate processing and memory units, neuromorphic systems integrate computation and storage in distributed networks, much like biological brains 5 .
This architectural shift enables dramatic improvements in energy efficiency and processing speed for specific tasks, particularly those involving pattern recognition and sensory data processing.
The Alpho-RC System
One of the most compelling recent experiments in bioinspired computing comes from a team that developed a bioinspired in-materia analog photoelectronic reservoir computing (Alpho-RC) system for human action processing 3 .
This remarkable system was built using Indium-Gallium-Zinc-Oxide (IGZO) photoelectronic synaptic transistors as the reservoir and a TaOX-based memristor array as the output layer 3 .
The Alpho-RC system achieved remarkable results, demonstrating greater than 90% recognition accuracy across four standard human action datasets. Perhaps even more impressively, the system recognized falling behaviors with exceptionally low energy consumption of approximately 45.78 μJ per action—at least two orders of magnitude lower than digital processors 3 .
