Bioprinting High‐Cell‐Density Cardiac Tissue Constructs With Sustained Contractile Function

Advanced Healthcare Materials, EarlyView.
Contractile cardiomyocytes in 3D culture provide insights into the behavior of the heart. Combining a 3D bioprinting approach with a multi‐electrode array allows the development of the 3D culture to be monitored over time, and matured cultures allow the effect of drugs on cardiac function to be modelled, replicating effects seen in clinical application.

Effect of finite cracking on the electromechanical coupling properties of piezoelectric materials [PDF]

, 2010
Cracks and porosities inside the piezoelectric materials can weaken the electromechanical coupling effect, and hence influence the electromechanical coupling behavior of piezoelectric materials considerably.

Patient‐Derived 3D Heart‐On‐a‐Chip Model of Dilated Cardiomyopathy With Embedded Bead‐Based Mapping of Tissue Contractility

Advanced Healthcare Materials, EarlyView.
A heart‐on‐a‐chip model of dilated cardiomyopathy is developed from patient‐derived induced pluripotent stem cells. The model recapitulates key disease phenotypes and enables functional assessment through integrated bead‐based tracking and pillar deflection measurements.
