A layer of ruthenium just a few atoms thick can be used to fine-tune the sensitivity and enhance the reliability of magnetic sensors, tests at NIST show. The nonmagnetic metal acts as a buffer between ...

Littelfuse has created a three pin magnetic switch that draws only 200nA and operates at up to 50Hz. Called LF21112TMR, the detector uses a combination of TMR (tunnelling magneto-resistance) sensing ...

ITHACA, N.Y. - As with actors and opera singers, when measuring magnetic fields it helps to have range. Cornell researchers used an ultrathin graphene "sandwich" to create a tiny magnetic field sensor ...

One of the primary ways that gyroscopic motion can be applied is in the monitoring and/or maintaining of the orientation of an object. A broad array of engineering applications are based on gyroscopic ...

Dispersible electrodes based on gold-coated magnetic nanoparticles modified with DNA can detect microRNA in unprocessed blood samples at extremely low concentrations and over a broad range – a first ...

(Nanowerk News) A layer of ruthenium just a few atoms thick can be used to fine-tune the sensitivity and enhance the reliability of magnetic sensors, tests at the National Institute of Standards and ...

Researchers used an ultrathin graphene 'sandwich' to create a tiny magnetic field sensor that can operate over a greater temperature range than previous sensors, while also detecting miniscule changes ...
