脳と同様に、イオンを使った新しい電子部品であるナノ流体メモリ素子の開発が進行中。従来のコンピュータはデータのやり取りにエネルギーを多く必要とするが、この新技術は脳のような効率的な情報処理を可能にする。これにより、よりエネルギー効率の高いコンピュータや脳-コンピュータインターフェースが可能になる見込み。

人工ナノ流体シナプスが計算記憶を保存可能に(Artificial nanofluidic synapses can store computational memory)

Abstract

Neuromorphic systems are typically based on nanoscale electronic devices, but nature relies on ions for energy-efficient information processing. Nanofluidic memristive devices could thus potentially be used to construct electrolytic computers that mimic the brain down to its basic principles of operation. Here we report a nanofluidic device that is designed for circuit-scale in-memory processing. The device, which is fabricated using a scalable process, combines single-digit nanometric confinement and large entrance asymmetry and operates on the second timescale with a conductance ratio in the range of 9 to 60. In operando optical microscopy shows that the memory capabilities are due to the reversible formation of liquid blisters that modulate the conductance of the device. We use these mechano–ionic memristive switches to assemble logic circuits composed of two interactive devices and an ohmic resistor.
