Transient Charging of Mixed Ionic‐Electronic Conductors by Anomalous Diffusion

open access: yesAdvanced Materials, EarlyView.
This article explores charge transport in mixed ionic‐electronic conductors (MIECs) through electrochemical impedance spectroscopy and transient current analysis. Focusing on PEDOT:PSS, WO3, and n‐doped PBDF, it uncovers the impact of anomalous diffusion via fractional modeling. The study reveals key correlations that deepen understanding and guide the

Intrinsic Safety of Capacitive-Resistive Circuit.

open access: yesShigen-to-Sozai, 1994
Electric-arc ignition test of methane gas has been carried out for some capacitive-resistive circuit models. The results of the minmum ignition voltages (Vm) for circuits with paticular parameters and with the discharged energy values, has been evaluated.

Electrically Readable Lateral Flow Assay Using Organic Transistors for Diagnostic Applications

open access: yesAdvanced Materials, EarlyView.
Electrolyte‐gated organic field‐effect transistors (EGOFETs) are integrated with lateral flow (LF) paper fluidics to create a reusable, portable, and low‐cost point‐of‐care (PoC) diagnostic test. The devices are validated for Human Immunoglobulin G detection, achieving high sensitivity (0.1 fm), selectivity, and reproducibility with rapid results in 20–

Research and improvement of operational amplifier stability in capacitive sensor driver circuits

open access: yesТехнологія та конструювання в електронній апаратурі, 2008
It has been shown that the instability of operational amplifiers in capacitive driver circuits is caused by a significant phase shift in the negative feedback loop, which leads to oscillation processes.

Differentiating circuits with nonlinear resistance and capacitance

open access: yesElectronics Letters, 1969
An RC differentiating network is described in which both elements are nonlinear. The new network is compared with circuits in which the capacitative element only is nonlinear, and some improvements in its pulse-shaping properties are demonstrated.
