An Organic Transistor Paves the Way for New Generations of Neuro-Inspired Computers
National Center for Scientific Research (France) (01/22/10)

Researchers at the National Center for Scientific Research have devised an organic transistor that can emulate a synapse's primary functionalities. The researchers say the breakthrough could lead to new generations of neuro-inspired computers capable of functions comparable to those of the human brain. The nanoparticle organic memory field-effect transistor (NOMFET) successfully mimics synapse plasticity. Gold nanoparticles are fixed in the transistor channel and coated with pentacene, and they have a memory effect that permits them to imitate the way a synapse operates during the transmission of action potentials between a pair of neurons. Thus the electronic element can evolve as a function of the system in which it is encapsulated. The NOMFET's performance matches that of at least seven complementary metal-oxide semiconductor transistors that up to now have been needed to mimic plasticity. Neuro-inspired computers can address visual recognition and other challenges that are beyond the capabilities of silicon computers.
