  • Using Surface Enhanced Raman Spectroscopy for Molecular Sensing
    Article - 20 Dec 2019
    In 1928, the famous Indian physicist CV Raman discovered the inelastic scattering of photons from an atom or a molecule. This effect was thus called Raman scattering or the Raman Effect.
  • Measuring Strain with Surface Acoustic Wave Devices
    Article - 27 Apr 2019
    Torque (radial) strain transducers are often used by development engineers, particularly when combined with the surface acoustic wave principle.
  • Metal Detectors
    Article - 4 Nov 2013
    Metal detectors are portable electronic devices used for detecting the presence of any metal close by. They operate by sensing changes in magnetic waves caused by metal. The metal objects can be...
  • Measuring Temperature in Electromagnetic Environments
    Article - 27 Sep 2017
    Temperature can be easily measured and recorded using a thermocouple. Thermocouples work consistently in most environments, tolerating vibration, temperature extremes and even ionizing radiation.
  • Vibration Sensor with Potential Use in Transparent Medical Devices
    Article - 17 Jun 2022
    The benefits of organic and inorganic hybrid materials in a wheel-shaped diaphragm structure were used to create a highly sensitive, transparent, and flexible vibration sensor.
  • Microphone – Sound Sensor
    Article - 28 Jun 2013
    A microphone is an acoustic to electric transducer or sensor that detects sound signal and converts them into an electrical signal. This conversion is relatively direct and the electrical vibration...
  • Flowmeter Verification: How is Self-Verification Achieved?
    Article - 13 Jan 2022
    Modern flowmeters are becoming increasingly advanced, with self-verification now an option to ensure reliable and accurate results. This articles elaborates on how this self-verification is achieved.
  • How to Integrate Board Level Cameras
    Article - 22 Mar 2021
    When transitioning from cased to board level cameras, system designers should carefully consider their imaging and camera performance requirements.
  • What are Infrared Temperature Sensors?
    Article - 24 Aug 2017
    Temperature is measured by an infrared intemperature probe by detecting the infrared energy produced by all materials which are at temperatures higher than absolute zero, (0 °K).
  • What are Optical Sensors?
    Article - 9 Oct 2024
    Optical sensors, key in various industries, convert light into data, detecting changes in intensity and wavelength for improved automation and monitoring.
