Bio-functional application of nano-electronic materials and creation of bio-mimetic devices

信号检测能力有时通过噪声的加入而增强，这被称为随机共振(SR)。在这项研究中，我们成功地利用VO_2薄膜的非线性响应，通过添加噪声来提高信号传输能力。此外，实验结果中的SR行为与模拟的多个平行单元的SR行为相一致。这表明在VO_2薄膜中应该自然地存在有效的多通道。这一成果对利用噪声作为生物系统的新型信息处理器具有充分的潜力。

The signal detection ability sometimes enhances by the addition of noise, which is called stochastic resonance (SR). In this research, we succeeded in enhancement of the ability of signal transfer by the addition of noise using non-linear response of VO_2 thin films. In addition, the SR behavior in the experimental results corresponded with the simulated SR behavior with multiple parallel units. This suggests that effective multiple channels should naturally exist in a VO_2 thin film. This achievement has fully potential to novel information processers using noise as bio-systems.
