Forces that are exerted by a living cell or a microorganism are tiny and often not larger than a few nanonewtons. For comparison, one nanonewton is the weight of one part in a billion of a typical ...

What is a Surface Force Apparatus (SFA)? The Surface Force Apparatus (SFA) is a highly sensitive scientific instrument used to measure the forces between two surfaces at the nanoscale. It allows ...

The goal of mechanobiology is to develop a mechanical description of cells and their parts. Platelet clotting, for example, is an important biological process that can only be fully understood if a ...

Researchers with the Lawrence Berkeley National Laboratory and the University of California Berkeley have measured what is believed to be the smallest force yet recorded – 42 yoctonewtons, or a ...

Researchers at the University of California San Diego and the Allen Institute of Cell Science have developed a new computational method that can measure the forces cells exert on each other by ...

Until about 10 years ago, the force test and measurement industry had been fairly unimaginative. It had developed a standard way of building analog load cells, torque transducers and other devices, ...

The Series M240 ICP Strain Sensors and Model 410A01 ICP signal conditioner use piezoelectric sensing elements to indirectly measure dynamic and quasi-static stress forces on machinery structures. M240 ...

Laser power measurement and force metrology are interlinked disciplines dedicated to quantifying the interaction between light and matter. In contemporary research, these fields have evolved from ...

In 1856, Lord Kelvin observed that metallic conductors subjected to mechanical strain exhibit a change in their electrical resistance. Since that time, engineers have attempted to measure and quantify ...

Novel technique to measure forces produced by microorganisms as they move without harming them hopes to shine light on how bacteria move. Forces that are exerted by a living cell or a microorganism ...
