Inductively Expandable Supraparticles as Microscopic Force Generators for Remote Mechanical Actuation

Advanced Materials, EarlyView.
This study demonstrates the combination of magnetic nanoparticles and functional blowing agents into supraparticles. Upon induction heating, they actuate via rapid gas generation or extensive volume expansion. These supraparticles lift up to 25 000 times their own mass and rapidly open cured epoxy resins, providing a versatile strategy for fast micron ...

Deep Eutectic Solvent‐Enhanced PEDOT: PSS/NR Foam Piezoresistive Sensor for High‐Sensitivity Wearable Devices and Sleep Monitoring Applications

Advanced Materials Interfaces, EarlyView.
A high‐performance piezoresistive foam sensor is developed by integrating natural rubber, PEDOT: PSS, and a deep eutectic solvent (DES). DES effectively detaches insulating PSS from PEDOT, dramatically amplifying electrical conductivity and sensitivity.

Laminar mixed convection boundary layer flow induced by a permeable surface stretched with prescribed skin friction boundary conditions

Advances in Mechanical Engineering, 2015
The mixed laminar boundary layer flow and heat transfer on a permeable stretched surface moving with prescribed skin friction are studied. Three major cases, which correspond to complete similarity solutions, are considered. The cases are combinations of

Skin‐Like Tri‐Modal Sensors Based on Soft Piezoelectric and Ionic Composites

Advanced Materials Technologies, EarlyView.
Inspired by the multimodal perception of human skin, a soft, skin‐like tri‐modal sensor is presented. The device incorporates an ionically conductive, piezoelectric, elastic composite as its active layer, enabling independent detection of temperature, static strain, and dynamic strain within a single two‐terminal architecture.
