A Three‐Phase Electrostatic Clutch with Variable Mechanical Impedance Control for Soft Robotic Systems

Advanced Science, EarlyView.
The research introduces a three‐phase electrostatic (ES) clutch with variable mechanical impedance control, specifically designed to enable continuous and precise friction modulation, thereby reducing both force degradation and oscillatory motion. This method effectively resolves conventional ES clutch issues, such as residual charge accumulation and ...

Needle‐free, Liquid Metal‐embedded Electrospray Deposition System for Controlled Microdroplet Printing

Advanced Science, EarlyView.
The liquid metal‐embedded electrospray deposition (LM‐ESD) system combines stable droplet spray, clog‐free and recoverable operation, and simplified fabrication in a single polydimethylsiloxane (PDMS) microfluidic platform. By eliminating external electrodes, it offers needle‐free, robust, and scalable droplet array printing, ensuring reproducibility ...

Gate‐Dielectric Surface Engineering With Fluorinated Monolayers: Minimizing Contact Resistance and Nonidealities in OFETs

Advanced Electronic Materials, EarlyView.
Surface engineering of gate dielectrics with fluorinated self–assembled monolayers significantly improves the performance of organic field–effect transistors. In this study, Al2O3 functionalized with fluorinated phosphonic acids reduces contact resistance and hysteresis while achieving near‐zero threshold voltages, offering an alternative to ...
