Shapeshifting Liquid Metal Droplets for Soft Fluidic Machines

open access: yesAdvanced Materials, EarlyView.
This study presented a liquid metal shape shifting strategy which harnesses Lorentz force, surface tension and fluid instabilities to achieve autonomous fluidic power. By using a liquid metal droplet as a mobile current carrier, this strategy enables the development of low‐voltage, self‐oscillating pumps that outperform existing soft pumps.

Measuring Zn Transference with Precision: Insights for Dendrite‐Free Zinc Metal Anodes

open access: yesAdvanced Materials, EarlyView.
A modified Hittorf method reveals how co‐salt composition affects Zn2+ transference numbers. Coupled with molecular dynamics and spectroscopy, we shows that electrolytes with high Zn transference number (tZn) suppress dendrites, enabling longer high‐rate cycling and more stable Zn‐metal anodes.

Capillary‐Driven 3D Open Fluidic Networks for Versatile Continuous Flow Manipulation

open access: yesAdvanced Materials, EarlyView.
The capillary‐driven 3D open fluidic networks (OFNs), composed of connected polyhedral frames, enable precise, programmable, and versatile manipulation of unary, binary, and multiple continuous flows in both spatial and temporal dimensions. OFNs represent a significant leap beyond conventional microfluidics, unlocking new possibilities for selective ...

Modified pseudo-elastic approach for modelling cyclic response of biological heart valves [PDF]

open access: yes, 2016
A modified pseudo-elastic approach is proposed to model cyclic response on biological heart valves. The model takes into account hysteretic effects, in combination with hyperelastic anisotropic behaviour of valve leaflets, allowing reproduction of ...

Self‐Spiking Linear Neuromorphic Soft Pressure Sensor for Underwater Sensing Applications

open access: yesAdvanced Materials, EarlyView.
This study presents a novel design of a neuromorphic pressure sensor that can generate self‐spiking symmetric signals with direct event‐based encoding through the integration of magnetic spheres and alternating coil circuits. The key advantages of this work include high linearity up to 200 kPa (R2 = 0.997), self‐spiking behavior for simplified signal ...
