Additive Manufacturing of Stretchable Zipping Electrostatic Actuators through Spray Encapsulation of a Frozen Liquid

Advanced Materials Technologies, EarlyView.
This work presents a method to print multi‐layer elastomer structures containing liquid cavities, where the fluid is incorporated as part of the printing process by freezing it, thus avoiding the conventional final filling step. We demonstrate this process by fabricating and characterizing dense arrays of zipping electrostatic actuators.

A computed tomography‐based survey of paramedullary diverticula in extant Aves

The Anatomical Record, Volume 306, Issue 1, Page 29-50, January 2023., 2023
Abstract Avian respiratory systems are comprised of rigid lungs connected to a hierarchically organized network of large, regional air sacs, and small diverticula that branch from them. Paramedullary diverticula are those that rest in contact with the spinal cord, and frequently invade the vertebral canal.

4D Printed Self‐Deploying Bio‐Based Scaffolds for the Regeneration of Endoluminal Tissue

Advanced Materials Technologies, EarlyView.
A bilayer self‐deploying tubular C‐shaped scaffold, made of natural polymers and triggerable by humidity, is fabricated via 4D printing for the regeneration of gastro‐intestinal tissue. The choice of the materials and their spatial arrangement is guided by physical and biological evaluation, whereas the geometry of the structure is optimized through ...

Morphologies in‐between: The impact of the first steps on the human talus

The Anatomical Record, Volume 306, Issue 1, Page 124-142, January 2023., 2023
Abstract Objective The development of bipedalism is a very complex activity that contributes to shaping the anatomy of the foot. The talus, which starts ossifying in utero, may account for the developing stages from the late gestational phase onwards.

Fully Printed Variable Orifice Flowmeter with Built‐In Temperature Compensation for Application in Mechanical Ventilation

Advanced Sensor Research, EarlyView.
Additive manufacturing, specifically fused deposition modeling, offers an innovative approach to creating 3D‐printed variable orifice flowmeters with integrated temperature compensation. Using carbon‐black TPU, the primary component (a variable orifice) and the secondary element (a diaphragm pressure sensor) are fabricated.

Variation and development of the turtle chondrocranium, with a description of the common musk turtle (Sternotherus odoratus, Kinosternidae, Cryptodira, Testudines)

The Anatomical Record, EarlyView., 2023
Abstract Based on histological cross‐sections, the chondrocranium of the common musk turtle (Sternotherus odoratus) was reconstructed, described, and compared with other turtles. It differs from that of other turtle chondrocrania by possessing elongated, slightly dorsally orientated nasal capsules with three dorsolateral foramina, which might be ...
