An inductive sensor is a device that uses the principle of electromagnetic induction to detect or measure objects. An inductor develops a magnetic field when an electric current flows through it; alternatively, a current will flow through a circuit containing an inductor when the magnetic field through it changes.
An infrared proximity sensor Optical proximity sensor in a 2016 Samsung smartphone. A proximity sensor is a standard feature of most smartphones, disabling the touchscreen when positioned near an ear during phone calls; more recent (late 2019-early 2020) smartphones with OLED displays may have the sensor mounted under the display.
Types of crank sensor include: the inductive sensor, Hall Effect sensor, magnetoresistive sensor, and optical sensor. Inductive sensors have the simplest construction and are usually purely passive devices. Hall effect and magnetoresistive sensors have the advantage over inductive sensors in that they can detect static (non-changing) magnetic ...
An induction or inductive loop is an electromagnetic communication or detection system which uses a moving magnet or an alternating current to induce an electric current in a nearby wire. Induction loops are used for transmission and reception of communication signals, or for detection of metal objects in metal detectors or vehicle presence ...
A VR sensor used as a simple proximity sensor can determine the position of a mechanical link in a piece of industrial equipment. A crankshaft position sensor (in an automobile engine) is used to provide the angular position of the crankshaft to the engine control unit. The engine control unit can then calculate engine speed (angular velocity).
A ribosome is a biological machine that utilizes protein dynamics. At the first C.E.C. Workshop, in Brussels in November 1991, bioelectronics was defined as 'the use of biological materials and biological architectures for information processing systems and new devices'.
Editor's note: Follow here for updates on Trump's Cabinet on Monday, Nov. 11. Now that it's clear President-elect Donald Trump will return to for a second White House term, speculation into who he ...
In 2006, A proof of concept was shown for CNT-SQUID sensors built with an aluminium loop and a single walled carbon nanotube Josephson junction. [16] The sensors are a few 100 nm in size and operate at 1K or below. Such sensors allow to count spins. [17] In 2022 a SQUID was constructed on magic angle twisted bilayer graphene (MATBG) [18] [19]
