Researchers have developed a novel negative-stiffness isolation device that offers a pioneering solution for seismic protection. The device, designed to provide multidirectional negative stiffness and ...

Technology advances have steadily been implemented to improve the performance of commercial atomic force microscopes (AFMs) since the release of the first commercial model about 30 years ago. Now, the ...

A revolutionary concept in low-frequency vibration isolation is utilized in Minus K ® vibration isolators.Vertical-motion isolation is supplied by a negative-stiffness mechanism (NSM) combined with a ...

Minus K® isolators typically use three isolators stacked in series: a tilt-motion isolator on top of a horizontal-motion isolator on top of a vertical-motion isolator. Figure 2 is an illustration of a ...

Negative-stiffness mechanical isolators can be used for achieving high-performance vibration isolation in a small microscope platform. It can be challenging to use microscopy for imaging materials, ...
