Volumetric 3D Printing and Melt‐Electrowriting to Fabricate Implantable Reinforced Cardiac Tissue Patches

open access: yesAdvanced Materials, EarlyView.
This study presents an implantable reinforced cardiac patch (RCPatch) combining volumetrically 3D‐printed metamaterials with melt‐electrowritten (MEW) meshes. The design integrates tunable stiff polymer structures with soft, cell‐laden hydrogels. The RCPatch withstands suturing, intraventricular pressure, and cardiac contraction in a large animal ...

Sacrificial Biofabrication for Vascularization: Concept, Materials, Technologies, and Applications

open access: yesAdvanced Materials, EarlyView.
Vasculature is indispensable for tissue viability in regenerative medicine. The sacrificial biofabrication enables precise fabrication of vascular channels by using temporary templates that are subsequently removed. This review defines the concept and delves into sacrificial materials, surrounding materials, fabrication technologies, and biomedical ...

Autonomous Implants

open access: yesAdvanced Materials, EarlyView.
An ideal implant should mimic native tissues such that it can integrate, sense, heal, and continue to function, i.e., be autonomous. Although early, there are good steps taken in this way, e.g., the development of stimuli‐responsive, self‐powering, self‐actuating, self‐healing, self‐regenerating, and self‐aware implants.

Spatially Programmable Electroadhesive Enables In Situ Site‐Selective Functional Coupling

open access: yesAdvanced Materials, EarlyView.
A light‐activated, in situ spatially programmable bioadhesive (STICH) enables microscale, site‐selective integration of bioelectronic devices with wet tissue. It achieves robust mechanical bonding and low‐impedance electrical coupling, enabling reconfigurable neuromodulation and directional electromechanical sensing in vivo and ex vivo.
