The primary objective of this project is to implement arrays of flexible optical neuromorphic devices using organic photochromic materials. By utilizing light-sensitive photochromic materials, the energy consumption of such devices will be reduced compared to the conventional approach, where voltages are required for "writing" and "erasing". Moreover, different photochromic materials respond differently to different wavelengths, thereby enabling multiple opportunities for functionalization and selective response based on the wavelength. Optical neuromorphic array components can efficiently execute parallel and distributed processing by emulating the brain's operation. Particularly, utilizing optical signals as stimuli instead of electricity can significantly reduce energy consumption in these components. In short: This project aims to implement low-voltage, and low-power neuromorphic devices using optical signals, with the ultimate goal of scaling up to arrays. The international consortium, comprised of experts from various fields including materials science, electronics, and nanotechnology, possesses the requisite capabilities and experience to effectively address these challenges and significant barriers in this emerging technology.
