Bio‐Inspired Internal Stress Engineering for Microscale Surface Cracking in Sensitive Strain Sensors

Advanced Science, EarlyView.
This study presents a bio‐inspired internal stress engineering strategy to fabricate highly sensitive crack‐based strain sensors. By harnessing the internal expansion energy of microspheres and the thickness‐dependent brittle‐to‐ductile transition of ultrathin gold films, tunable microscale cracks are generated.

Bio‐Inspired Gradient Heterogeneous Architectures for Ultrasensitive and Robust Strain Sensors via Programmable Crack Engineering

Advanced Science, EarlyView.
Inspired by the insect campaniform sensillum, a heterogeneous bilayer strain sensor is developed based on a unique impedance mismatch and three‐dimensional structural dynamic percolation strategy. The sensor enables real‐time multi‐joint teleoperation of three joints and the gripper using a six‐degree‐of‐freedom robotic‐arm platform.

Engineering Spatially Localized Bioactive Microenvironments in Assembly Implants for Spatially Extended Bone Ingrowth

Advanced Science, EarlyView.
An assembly porous titanium/β‐TCP implant is developed to establish a spatially programmable osteogenic microenvironment for enhanced osseointegration. By decoupling mechanical support from bioactive ion release, localized ionic gradients generated from the β‐TCP module direct osteogenic activity and bone ingrowth toward the porous titanium framework ...

Ferroionic Electrostatic Landscapes Enabling Wireless Energy Harvesting, Storage, and Sensing

Advanced Electronic Materials, EarlyView.
By integrating experiments and electrostatic field simulations, we show that long‐range wireless coupling in Li‐based ferroionics devices emerges from the cooperative interaction between ionic migration and electronic polarization. This coupling sustains self‐polarized electrostatic fields across centimeter‐scale air gaps without external bias or ...

Tuning Local Modulus at Liquid Metal‐Polymer Interfaces Regulates Electrocaloric Effect in Ferroelectric Nanocomposites

Advanced Electronic Materials, EarlyView.
Liquid metal nanoparticles create mechanically compliant polymer interfaces that facilitate reversible dipolar reorientation under electric fields, whereas rigid interfaces impose stronger local constraints. This soft–rigid interface comparison reveals local interfacial modulus as a key parameter for tuning electrocaloric entropy change in ...
