Flexural strength of dental restoratives

open access: yes, 2023
Background: New dental restorative material, “Cention Forte” and “Admira Fusion” have been available on the market for quite some time but are still new in comparison with traditional resin-based composite, “Ceram.x Spectra ST” and glass ionomer cement, “GC Fuji II LC”.

Shape‐Memory Alloy Torsion Strips for Soft Robotic Manipulation and Morphing

open access: yesAdvanced Intelligent Systems, EarlyView.
In this research, a dedicated configuration of SMA strip is proposed for soft robotic manipulation and morphing. This configuration has broad application prospects and demonstrates remarkable advantages in soft body joint operations. Mimicking invertebrates, soft robots tend to control each of their body joints to achieve the desired shape changes and ...

Effective Material Stiffness in Curved Actuators

open access: yesAdvanced Intelligent Systems, EarlyView.
A new actuator effective material stiffness measurement method is created. It produces a new metric called shape actuation modulus with the potential to help design actuators. This method shows that the smaller the curvature of hinge‐shaped actuators, the stiffer they are.

Phase‐Change Alloys Enable Localized Reversible Stiffening and Actuation in Steerable Eversion Tip‐Growing Robots

open access: yesAdvanced Intelligent Systems, EarlyView.
This work presents a tip‐growing eversion robot that uses phase‐changing alloys for reversible stiffening and localized actuation, achieving 43× stiffness modulation, 15× force amplification, and segmental steering. The system enables precise navigation and force delivery in constrained, tortuous pathways.

Tendon‐Driven Compliant Wheel‐Less Snake Robot for Undulatory Locomotion Using Conformable Ground Contacts

open access: yesAdvanced Intelligent Systems, EarlyView.
This study presents a tendon‐driven compliant snake robot that uses globally applied vertical bending and axial twisting along its body to enable various gaits. Body deflection from compliance and weight passively generates the ground contact patterns required for locomotion.
