Burn‐Safe Biodegradable Magnetocaloric Composites for Temperature‐Controlled Biomedical Applications

open access: yesAdvanced Science, EarlyView.
This work investigates a magnetocaloric (Mn,Fe)2(P,Si) compound tailored for precise, self‐regulating heating in biomedical use. With a Curie temperature tuned at 43 °C, it enables therapeutic activation without overheating. Encapsulation in a composite ensures controlled temperature rise under an alternating magnetic field (AMF), with high ...

Bio‐Inspired Micro‐Fin‐Assisted Multi‐Modal Vascular Intervention

open access: yesAdvanced Science, EarlyView.
A magnetic guidewire with a micro‐fin–integrated tip is introduced for multimodal cardiovascular navigation. The micro‐fins exploit fluid drag to augment magnetic torque, enabling bifurcation traversal at 15 mT, tolerating 45° misalignment, bidirectional crawling, and buckle self‐correction.

Ion‐Electron Fusion Transparent Film for Interactive Soft Robotics

open access: yesAdvanced Science, EarlyView.
An ion‐electron fusion transparent film with stable conductivity, high optical transmittance, and a broad linear strain‐sensing range of up to 300% is developed, attributed to the synergistic effects of ion penetration and microcrack design. When applied to soft robots, this film imparts proprioceptive sensing and underwater visible light communication
