Abstract: Variable stiffness structures are essential in soft wearable robotics, where both flexibility and load-bearing capacity are required within a single design. However, achieving stiffness ...

Bolted joints are among the most common structural elements in precision machinery. They are used because they are strong, serviceable and reliable. Yet, despite their prevalence, the moment stiffness ...

Abstract: The concentric cable-driven manipulator has characteristics of flexibility and slenderness when working in confined space. However, how to optimize a structure with appropriate stiffness ...

Depending on the cause, physical therapy, massage, stretching, yoga, relaxation, heat, or other therapies may help release chronically tight muscles. Various factors can cause chronically tight or ...

Princeton engineers are twisting, stretching and creasing structures to create a new type of origami, one that changes its shape and properties in response to changing circumstances. The new method ...

A total knee replacement, also known as knee arthroplasty, can feel like a second chance at life after years of dealing with a sore, arthritic knee. While most people achieve improved range of motion ...

Generative A.I. chatbots are going down conspiratorial rabbit holes and endorsing wild, mystical belief systems. For some people, conversations with the technology can deeply distort reality. By ...

Maybe you’re lucky enough to have felt a runner’s high, when the breeze, sun, and your mood make it clear that humans were born to run. On the other hand, maybe you’ve also logged time in waiting ...

Researchers engineer a new class of microlattice materials with enhanced stiffness-to-density ratios and giant negative Poisson's ratios, ideal for lightweight applications. (Nanowerk Spotlight) ...
