Elimination of Necking and Aspect Ratio Dependence in Uniaxial Actuators by Continuous Fiber Reinforcement

open access: yesAdvanced Robotics Research, EarlyView.
A novel carbon fiber reinforcement for dielectric elastomer actuators enhances actuation force while decoupling electromechanical performance from the actuator's aspect ratio. Unlike conventional fiber reinforcements, it enables a uniform planar stretch state along the entire actuator.

A Soft Robotic Fish With a Dielectric Elastomer Actuator Body and Negative Stiffness Spine

open access: yesAdvanced Robotics Research, EarlyView.
This work introduces a bio‐mimetic soft robotic fish driven by fiber‐reinforced dielectric elastomer actuators integrated as its body. By prestretching this active skin against a flexible spine, a negative stiffness system is created, enabling large‐amplitude bending.

The influence of the raster angle on the dimensional accuracy of FDM-printed PLA, PETG, and ABS tensile specimens

open access: yesEuropean Mechanical Science
3D printing is a rapidly advancing method in digital manufacturing techniques and produces objects in layers. Fused Deposition Modelling (FDM) is a 3D printing technology where the material is melted in a hot nozzle and then placed on a build platform to

A bacterial gene-drive system efficiently edits and inactivates a high copy number antibiotic resistance locus. [PDF]

open access: yes, 2019
Gene-drive systems in diploid organisms bias the inheritance of one allele over another. CRISPR-based gene-drive expresses a guide RNA (gRNA) into the genome at the site where the gRNA directs Cas9-mediated cleavage.

Moisture absorption of 3D-printed PETG plastic samples

open access: yesVestnik MGSU, 2023
Introduction. The additive manufacturing method implies the emergence of emergent properties in the final product, not inherent in the original elements of the system individually. Performance properties of products obtained by FDM-printing are defined not only by the material properties, but also by printing parameters — nozzle and table temperature ...
