The human brain is the ultimate supercomputer. It uses a highly branched and interconnected network of neurons and synapses to achieve massive computational power with extreme efficiency. In the age of AI, the brain, a paradigm of efficient neuromorphic computing, is providing inspiration for scientists.

Ionic computing—which uses ions to compute instead of the electrons in typical devices—could provide a path forward for neuromorphic technology that rivals the brain’s efficiency. But the field is only a few years old, and many challenges remain before it moves beyond proof of principle and toward real-world deployment.

Artificial neurons replicate biological function for improved computer chips

Artificial neurons developed by USC team replicate biological function for improved computer chips
An integrated spiking artificial neuron, with rich neuron functionality, single-transistor footprints, and low energy consumption for neuromorphic computing systems, can be created by stacking one diffusive memristor and one resistor on top of a transistor. The photograph on the cover shows the chip of an array of these integrated neurons, which are fabricated in the university’s cleanroom and have an active region of around 4 μm2 for each neuron.

Self-powered artificial synapse mimics human color vision

Self-powered artificial synapse mimics human color vision
The top half of this image depicts the proposed artificial synapse made using dye-sensitized solar cells. The plot shows the bipolar voltage response of the synapse depending on the wavelength of light used, which mimics how our eyes perceive the world and enables logic operations. The bottom half of the image shows an experiment in which the proposed system was used to capture and classify various human movements.

We often believe computers are more efficient than humans. After all, computers can complete a complex math equation in a moment and can also recall the name of that one actor we keep forgetting. However, human brains can process complicated layers of information quickly, accurately, and with almost no energy input: recognizing a face after only seeing it once or instantly knowing the difference between a mountain and the ocean. These simple human tasks require enormous processing and energy input from computers, and even then, with varying degrees of accuracy.
