Soft Polymer 'Synaptic Transistors' Mimic Brain Plasticity
Researchers have developed a brain-like computing device that is capable of learning by association.

non-volatile synaptic organic electrochemical transistor)
The device’s secret lies within its novel organic, electrochemical “synaptic transistors,” which simultaneously process and store information just like the human brain. The researchers demonstrated that the transistor can mimic the short-term and long-term plasticity of synapses in the human brain, building on memories to learn over time.With its brain-like ability, the novel transistor and circuit could potentially overcome the limitations of traditional computing, including their energy-sapping hardware and limited ability to perform multiple tasks at the same time. The brain-like device also has higher fault tolerance, continuing to operate smoothly even when some components fail.
“Although the modern computer is outstanding, the human brain can easily outperform it in some complex and unstructured tasks, such as pattern recognition, motor control and multisensory integration,” said Northwestern’s Jonathan Rivnay, a senior author of the study. “This is thanks to the plasticity of the synapse, which is the basic building block of the brain’s computational power. These synapses enable the brain to work in a highly parallel, fault tolerant and energy-efficient manner. In our work, we demonstrate an organic, plastic transistor that mimics key functions of a biological synapse.”
This approach was conceptualized nearly a century ago in the wonderful 1926 story The Metal Giants, by Golden Age science fiction writer Edmond Hamilton, published in Weird Tales:
...Detmold had attacked the problem from a different standpoint. It was his theory that the sensations of the nervous system are flashed to the brain as electric currents, or vibrations, and that it was the action of these vibratory currents on the brain-stuff that caused consciousness and thought. Thus, instead of trying to make simple, living cells and from them work up the complicated structure of the brain, he had constructed an organ, a brain, of metal, entirely inorganic and lifeless, yet whose atomic structure he claimed was analogous to the atomic structure of a living brain. He had then applied countless different electrical vibrations to this metallic brain-stuff, and finally announced that under vibrations of certain frequencies the organ had showed faint signs of consciousness.
