Advanced Functional Materials, EarlyView.Low‐frequency noise spectroscopy defines the resolvable conductance states of synaptic FeFETs by coupling read‐current fluctuation with usable dynamic range. The resulting noise‐limited bit precision establishes a universal, device‐agnostic reliability metric beyond the memory window, enabling quantitative benchmarking and rational design of high ...

An Edible Chitosan‐Based Acoustic Sensor for Sound‐Responsive Actuation in Edible Robots
Advanced Functional Materials, EarlyView.This study introduces an edible acoustic sensor for robotic food and edible robotics. Built from a chitosan piezoelectric film between gold electrodes, the sensor enables acoustic communication through ON/OFF keying. Integrated into an edible robot with pneumatically actuated arms and neck, it responds to high‐frequency tones.

Mathematical and Computational Applications, 2018 The principal aim of a spectral observer is twofold: the reconstruction of a signal of time via state estimation and the decomposition of such a signal into the frequencies that make it up. A spectral observer can be catalogued as an online algorithm for

Charge‐Tunable Coacervate Micelles for Separator Engineering in Lithium‐Sulfur Batteries
Advanced Functional Materials, EarlyView.A separator engineering strategy based on charge‐tunable complex coacervate core micelles (C3Ms) is presented to form an ion‐selective layer regulating polysulfide transport in Li–S batteries. The micelles enable uniform adsorption onto commercial polypropylene separators and infiltration throughout the internal pore network, suppressing polysulfide ...

Self‐Assembled Lipids as Soft Dielectrics
Advanced Functional Materials, EarlyView.Self‐assembled lipid bilayers serve as soft dielectric materials for ultrathin electronics. Using liquid‐metal parallel‐plate junctions, the capacitance and dielectric breakdown of dehydrated lipid films are characterized. Dielectric behavior is controlled by lipid molecular structure, cholesterol content, and assembly conditions, providing molecular ...
