Direct‐Ink‐Writing Printed Stretchable Eutectic Gallium–Indium Antenna for Robust Wireless Communication

Advanced Science, EarlyView.
In summary, a universal EGaIn‐based DIW printing strategy is presented for fabricating wideband stretchable antennas. The printed antenna achieves an operating bandwidth of 3.75–8.21 GHz (fractional bandwidth: 75%), a peak gain of 1.8 dB and a radiation efficiency of 76.6%, surpassing state‐of‐the‐art stretchable antennas. More importantly, the antenna

3D‐Printed Biomimetic Vascular Scaffold Crosslinked with Heparan Sulfate for Sustained Release of PDGFB‐LG4 Fusion Protein Promotes Bone Regeneration

Advanced Science, EarlyView.
Fusion protein PDGFB‐LG4 exhibits superior osteoinductive and angiogenic activity compared to PDGFB. The PCLHS‐PDGFB‐LG4 scaffold, featuring perfusable and permeable vascular‐like networks, promotes angiogenesis and osteogenesis through the sustained release of PDGFB‐LG4, thereby accelerating the bone defect repair process.

A Hollow Shell‐Lattice Soft Robot in Flexible Pipelines with Flowing Fluids

Advanced Science, EarlyView.
This study proposes a novel shell‐lattice robot with hollow bodies, capable of crawling through pipes with flowing fluids of high velocities and viscosities and mixed with impurities. The robot also features capabilities of crawling with high payloads, in curved pipes, and unthethered crawling. These unique properties make this robot high promising for
