AI Article Synopsis
- Bipolar junction transistors are crucial in modern electronics due to their ability to regulate voltage levels, leading to the development of a redox active binary logic gate (RLG) that can store binary data without external voltage.
- The RLG operates with specific configurations of half-cell electrodes to represent logic low and high levels, relying on fast self-charge injection in a polypyrrole-based system.
- The impressive characteristics of the RLG allow it to be used in innovative applications, such as designing a security sensor capable of detecting and counting intruders with high precision and speed.
Article Abstract
Bipolar junction transistors are at the frontiers of modern electronics owing to their discrete voltage regulated operational levels. Here we report a redox active binary logic gate (RLG) which can store a "0" and "1" with distinct operational levels, albeit without an external voltage stimuli. In the RLG, a shorted configuration of half-cell electrodes provided the logic low level and decoupled configuration relaxed the system to the logic high level due to self-charge injection into the redox active polymeric system. Galvanostatic intermittent titration and electrochemical quartz crystal microbalance studies indicate the kinetics of self-charge injection are quite faster and sustainable in polypyrrole based RLG, recovering more than 70% signal in just 14 s with minor signal reduction at the end of 10000 cycles. These remarkable properties of RLGs are extended to design a security sensor which can detect and count intruders in a locality with decent precision and switching speed.
