Advances in Nanochannel Energy Harvesting and Computing System

In this study, we explore the innovative application of nano-channel technologies in energy harvesting from saline solutions and the development of efficient memristor computing systems. By utilizing nano-channels compatible with silicon fabrication processes, we have devised a methodology for mass-producing devices capable of exploiting the unique properties of saline solutions for energy generation and computing. Specifically, our work delves into the fabrication of SiO2 nano-channels for extracting energy from salt gradients, alongside the creation of high-efficiency nano-channel memristors using two-dimensional materials. Through rigorous experimentation, we have achieved a significant breakthrough in energy generation density, reaching up to $705\mathrm{W}/ \mathrm{m}^{2}$ with our silicon-based nano-channels. Moreover, our nano-channel memristors demonstrate a rapid response to pulse signals, marking a clear distinction between short-term and long-term memory effects, which is crucial for the advancement of neuromorphic computing systems.
