Research Abstract

Stochastic resonance (SR) plays a crucial role in signal transmission in neuronal systems that are constantly exposed to ambient noise. In various technological areas, SR has generated interest because of the possibility of using it in sensing applications to detect weak signals even in a noisy environment. SR device consists of comparator and noise generator . In this research, we succeeded in fabrication of VO 2nano-materials having built-in the both functions. This achievement has fully potential to novel information processers using noise as bio-systems.
