Improved Direct Ink Writing of Liquid Metal Foams via Liquid Additives

Advanced Electronic Materials, EarlyView.
The ability to pattern liquid metal is useful for making soft electrical and thermal devices. Dispensing liquid metal from a nozzle naturally results in the formation of spheroidal droplets, making direct‐write printing challenging. Liquid metal foams containing pockets of air can extrude as filaments, albeit inconsistently.

Torque‐Transmitting Architected Metamaterials for Flexible and Extendable Tubular Robotics

Advanced Intelligent Systems, EarlyView.
Soft and continuum robots commonly rely on fluid, tendon, or rod‐based power transmissions, to control robotic form and actuation. This study presents an architected structure, based on patterned straight‐line mechanisms, that enables simultaneous bending, extending, and torsionally rigid (BETR) transmission.

Low‐Cost Friction‐Based Force‐Limiting Connection With Reduced Sensitivity to Machining Tolerances and Accelerated Repairability

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This paper presents a novel yet practical friction‐based structural component design for low‐damage earthquake‐resistant structures. The proposed connection design is based on a conventional slotted‐bolted configuration with the novelty being the use of loose steel washer plates to establish the friction‐sliding interface.
