This study presents a newly engineered nonlinear stiffness-softening mechanism that enables micro-electro-mechanical systems (MEMS) accelerometers to operate with dramatically reduced bias force and ...

The team of researchers led by Prof. Kristian Franze found that increasing tissue stiffness induces the expression of chemical signals that are typically absent in those regions. Semaphorin 3A is one ...

Design engineers routinely rely on bolted joints, yet most guidance focuses on axial stiffness—often overlooking moment (pitch) stiffness, which can dominate compliance in ...

Your muscles and joints might notice the cold weather before you do.

It’s easy to blame aging, an old mattress, or a poor night’s rest when you wake up feeling stiff and achy. It's true that those things can make you feel stiff in the morning. But if it happens a lot, ...

The arteries are blood vessels that deliver oxygen and vital nutrients to all the vital organs and peripheries in the body. The heart pumps blood through these vessels and with each pulse blood flows ...

Potential causes of knee stiffness include injury, arthritis, or arthrofibrosis. Certain types of arthritis are more common in older adults and people with previous knee injuries. People may be able ...

Your hip joint helps you move from a sitting position to a standing, walking, running, or jumping position. These activities are difficult, if not impossible, with a stiff hip. Each step or movement ...

Hydrogels are soft, jelly-like materials that can absorb large amounts of water. They are widely used in medical technologies ...
