Mechanical vibration generated by electron spins

Micro mechanical elements are indispensable components of modern electrical devices, but the actuation of them requires electrical current. It becomes harder to wire the element as further downscaling of device is pursued. ...

Remote control actuation goes down to nanoscale

Researchers of the Nanomagnetism Group and Electron Microscopy Group at CIC nanoGUNE devised and demonstrated a novel approach to nanoactuation that relies on magnetomechanics instead of the conventional electromechanics ...

Physicists develop ultrasensitive nanomechanical biosensor

Two young researchers working at the MIPT Laboratory of Nanooptics and Plasmonics, Dmitry Fedyanin and Yury Stebunov, have developed an ultracompact, highly sensitive nanomechanical sensor for analyzing the chemical composition ...

Measuring the mass of molecules on the nano-scale

Working with a device that slightly resembles a microscopically tiny tuning fork, researchers at the University of Tsukuba in Japan have recently developed coupled microcantilevers that can make mass measurements on the order ...

Detecting extraterrestrial life using mechanical nanosensors

Looking for life on other planets is not straightforward. It usually relies on chemical detection, which might be limited or even completely irrelevant to alien biology. On the other hand, motion is a trait of all life, and ...

Nanomechanical sensors detect cancer from breath

An array of functionalised membrane-type surface stress sensors (MSS) distinguishes cancer patients from healthy people through a signature response to breath samples.

JILA's short, flexible, reusable AFM probe

(Phys.org) —JILA researchers have engineered a short, flexible, reusable probe for the atomic force microscope (AFM) that enables state-of-the-art precision and stability in picoscale force measurements. Shorter, softer ...

Microscopic fountain pen to be used as a chemical sensor

The Atomic Force Microscope (AFM), which uses a fine-tipped probe to scan surfaces at the atomic scale, will soon be augmented with a chemical sensor. This involves the use of a hollow AFM cantilever, through which a liquid ...

Cantilever

A cantilever is a beam anchored at only one end. The beam carries the load to the support where it is resisted by moment and shear stress. Cantilever construction allows for overhanging structures without external bracing. Cantilevers can also be constructed with trusses or slabs.

This is in contrast to a simply supported beam such as those found in a post and lintel system. A simply supported beam is supported at both ends with loads applied between the supports.
