Traditionally, a long boom is used to distance the fluxgate magnetometers from the contaminate magnetic field generated by the spacecraft, itself, and at least two sensors are used to characterize ...

Atomic SERF magnetometers achieve very high magnetic field sensitivity by monitoring a high density vapor of alkali metal atoms precessing in a near-zero magnetic field. They are among the most ...

Linear velocity sensors measure the linear velocity of an object using either contact or noncontact techniques. Important performance specifications to consider when searching for linear velocity ...

A Superconducting Quantum Interference Device (SQUID) is an extremely sensitive magnetometer that measures very subtle magnetic fields. It exploits the quantum mechanical properties of ...

In recent years, advances in photonics and materials science have led to remarkable developments in sensor technology, pushing the boundaries of what can be detected and measured. Among these ...

Just like smartphone cameras, these sensors have a finite resolution. The higher the resolution, the finer details the sensor can discern about your finger, increasing the level of security.

A sensitive upconversion nanocrystal-based biometric optical tactile sensor instantaneously and quantitatively decomposes dynamic touch signals into individual components of vertical normal and ...

Both sensors measure rate of change; they just measure the rate of change for different things. In practice, that means that an accelerometer will measure the directional movement of a device but ...

In February 2021, the team conducted experimental detection of aircraft engines using drone-mounted magnetometers, laying the groundwork for the technology that would later be used in the field. These ...

Electrochemical methods are promising for monitoring neurochemical dynamics, but are limited by inflammation effects from electrode implantation. Here, the authors report the development of a ...
