使用功能材料的随机可激发阈值单元将潜在地成为用于生产具有超低能耗的噪声驱动的生物启发传感器和信息处理器的关键器件之一。特别地，噪声发生器和阈值单元将能够利用在包括结构、电偶极子、磁性和自旋的材料中发现的波动来制造。本文主要利用~（13）C固体核磁共振研究了高分子动力学，以及π共轭高分子在有序-无序相变或扭曲玻璃化转变附近的扭曲动力学引起的结构涨落。π共轭聚合物的扭转动力学在未来电子器件的设计和生产中将是重要的，例如生物启发的随机信息处理器。
Stochastically excitable threshold units using functional materials will potentially be among the key devices for the production of noise-driven bio-inspired sensors and information processors with ultra-low energy consumption. In particular, a noise generator and threshold unit will be able to be fabricated utilizing the fluctuations found in materials that include structural, electric dipole, magnetic, and spin. This article deals with studies of polymer dynamics mainly by13C solid-state NMR and structural fluctuations due to twist dynamics of π-conjugated polymers near the order-disorder phase transition or twist glass transition. The twist dynamics of π-conjugated polymers will be important in the design and production of future electronic devices such as bio-inspired stochastic information processors.
