Sentences with phrase «changes electrical resistance»

The rarer titania - based variant does not generate its own voltage, but changes electrical resistance based on the oxygen concentration detected.

This novel kind of non-volatile memory saves information by changing the electrical resistance of a metal - insulator - metal structure.

A new study from the Cava lab has revealed a unifying connection between seemingly unrelated materials that exhibit extreme magnetoresistance, the ability of some materials to drastically change their electrical resistance in response to a magnetic field, a property that could be useful in magnetic memory applications.

Not exact matches

A century ago, Swiss psychologist Carl Jung used a crude galvanometer and electrodes attached to patients» hands to measure changes in electrical resistance on the skin of patients during various word - association experiments.

As a read head moves above bits of magnetic data, changes in the magnetic orientation of those bits alter the electrical resistance of electrons flowing through the sensor, translating the magnetic data into a stream of electrical pulses.

Conventionally such chemical sensors use only the change in the electrical current through the device or a change in the resistance of the device active channel.

The change in electrical resistance through a magnetic field is called magnetoresistance and is very important in technology.

Physicists at the U.S. Department of Energy's Ames Laboratory compared similar materials and returned to a long - established rule of electron movement in their quest to explain the phenomenon of extremely large magnetoresistance (XMR), in which the application of a magnetic field to a material results in a remarkably large change in electrical resistance.

The researchers found that migration of oxygen ions away from the contact area results in an abrupt change in the oxide lattice structure and an increase of electrical resistance.

These perovskites display what is called colossal magnetoresistance: their electrical resistance changes dramatically when exposed to a magnetic field, which makes them ideal for high - capacity data storage.

The change of resistance of a PT100 is tiny, about 0.00385 Ohm per degree Celsius, so you need an electrical amplifier to multiply the small corresponding change in voltage to a value acceptable by the datalogger (Thermistors have a much much greater resistance change per degree Celsius, but are more non-linear and more imprecise).

To improve the reliability of reported sea water temperature observations, a change to an electrical resistance or thermistor thermometer, specially designed and installed to measure the sea water temperature and having a remote indicator on the ship's bridge, is recommended.
