Field‐Programmed Anisotropy in Magneto‐Piezoelectric Composites for Material‐Encoded Mechanoperception

Advanced Materials, EarlyView.
Field‐programmed anisotropy imparts material‐level intelligence to soft composites. Magnetic torque dynamics drive magneto‐piezoelectric nanowires from random dispersion into deterministic axial alignment. The resulting hierarchical percolation networks confine electromechanical coupling to specific axes and intrinsically decouple superposed force ...

Cardiac prostheses: toward permanent implantation

Cleveland Clinic Journal of Medicine, 1984
The pneumatically actuated total artificial heart (TAH) can maintain normal physiology in man and in experimental animals for several months with extracorporeal pneumatic actuation through the skin. The ultimate goal is the development of a totally implantable cardiac prosthesis that functions for a minimum of two years. The Cleveland Clinic Foundation’

Can Elastomers Combine Stiffness, Toughness and Fatigue Resistance?

Advanced Materials, EarlyView.
This review studies how the molecular and macroscopic architecture of elastomers influence their mechanical properties including: stiffness, stretchability, toughness, fatigue resistance, and damping behavior. By linking the structure to performance, it proposes design principles for advanced elastomeric systems that combine mechanical properties ...

Evaluation of Correlation Between Development of Multiple Cracks in Nonendodontically Treated Tooth and Placement of Dental Implants with Prosthesis

Journal of Pharmacy and Bioallied Sciences
Background: The result of increased occlusal stresses might be fractures in the teeth. It is still unclear how possible risk factors may affect the occurrence of tooth cracks after dental implants with prostheses in nonendodontically restored teeth. Aim:

3D Printing of Stretchable, Compressible and Conductive Porous Polyurethane for Soft Robotics

Advanced Materials Technologies, EarlyView.
A 3D‐printable porous dopamine‐polyurethane acrylate elastomer results in conductive, stretchable, and compressible structures that can be metallized in situ through catechol‐mediated silver reduction. The resulting material function as both compliant soft robot with a and strain sensors without complex assemblies, enabling fully 3D‐printed soft ...
