Reliable Tissue Grasping in Robotic Minimally Invasive Surgery Enabled by Optical‐Based Slip Sensing

open access: yesAdvanced Engineering Materials, EarlyView.
An optical‐based slip sensing method using a complementary metal–oxide–semiconductor image sensor with a built‐in infrared light emitting diode enables real‐time detection of tissue slippage—including displacement, direction, and speed—in robotic minimally invasive surgery.

Microcellular Poly (Ethylene‐Co‐Vinyl Acetate)/Lignin Nanocomposites for Soft Ferroelectrets

open access: yesAdvanced Engineering Materials, EarlyView.
Lignin valorization for advanced porous polymer nanocomposites development and an upscaling route for continuous manufacturing of soft ferroelectrets for energy harvesting are studied. This work examines the role of lignin and carbon nanotubes (CNT) in modifying the mechanical, dielectric, and ferroelectret properties of poly (ethylene‐co‐vinyl acetate)

3D Bioprinting of Thick Adipose Tissues with Integrated Vascular Hierarchies

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
An advanced 3D bioprinting technique is used here to create thick adipose tissues with a central, vessel and extensive branching. The construct is made using alginate, gelatin and collagen‐based bioinks. Flow through the complex vessel network is demonstrated as well as its successful integration with a femoral artery following implantation in a rat ...
