Complex 3D microfluidic architectures formed by mechanically guided compressive buckling

Microfluidic technologies have wide-ranging applications in chemical analysis systems, drug delivery platforms, and artificial vascular networks. This latter area is particularly relevant to 3D cell cultures, engineered tissues, and artificial …

Pop-Up Conducting Large-Area Biographene Kirigami

We demonstrate the rapid, large-area transformation of bioenabled graphene laminates into multidimensional geometries for pop-up and stretchable applications. Water-vapor annealing facilitates the controlled plasticization of the multilayered silk …

Quantitative Prediction of Paravalvular Leak in Transcatheter Aortic Valve Replacement Based on Tissue-Mimicking 3D Printing

OBJECTIVES This study aimed to develop a procedure simulation platform for in vitro transcatheter aortic valve replacement (TAVR) using patient-specific 3-dimensional (3D) printed tissue-mimicking phantoms. We investigated the feasibility of using …

Dual-material 3D printed metamaterials with tunable mechanical properties for patient-specific tissue-mimicking phantoms

Patient-specific tissue-mimicking phantoms have a wide range of biomedical applications including validation of computational models and imaging techniques, medical device testing, surgery planning, medical education, doctor-patient interaction, etc. …

Paper-Based Triboelectric Nanogenerators Made of Stretchable Interlocking Kirigami Patterns

The development of stretchable energy generation devices is indispensable for achieving stretchable, self-powered electronic systems. In this paper, a type of highly stretchable triboelectric nanogenerators made from conventional, inelastic materials …
