Robust, Breathable and Stretchable Liquid Metal Composite Nanofibre for Physiological Electrical Signal Monitoring

Advanced Science, EarlyView.
A conductive TPU/liquid‐metal nanofibrous film is fabricated via ultrasonic dispersion, electrospinning, and mold imprinting. The film is breathable, stretchable, deformation‐stable, and provides electromagnetic shielding. n‐Butanol encapsulation mitigates liquid‐metal surface tension and improves biocompatibility. Stable ECG, EOG, EEG, and EMG signals

FPGA Implementation of a General Space Vector Approach on a 6-Leg Voltage Source Inverter [PDF]

, 2011
A general algorithm of a Space Vector approach is implemented on a 6-leg VSI controlling a PM synchronous machine with three independent phases. In this last case, the necessity of controlling the zero-sequence current motivates the choice of a special ...

Synergistic Mechano‐Fluidic Self‐Fusion of Poly(Vinyl Alcohol)‐Modified Liquid‐Metal Particles for Post‐Treatment‐Free Soft Electronics

Advanced Science, EarlyView.
Poly(vinyl alcohol)‐modified liquid‐metal particles form conductive networks through spray‐induced self‐fusion without additional post‐treatment. Spray impact initiates oxide‐shell rupture and electrical contact, while subsequent Marangoni flow and capillary forces promote particle redistribution, neck growth, and network consolidation. This sequential
