  • Ocean Acidity Detection System
    Article - 6 Jan 2014
    Studies reveal that ocean acidity is likely to double by 2100 because of carbon dioxide (CO2) pollution. The enormous amounts of CO2 absorbed into the oceans will change water chemistry and affect the...
  • Capacitance Probe Technology
    Article - 12 Feb 2014
    A capacitive sensor measurement system requires three components: a probe to detect any changes in distance to a target by sensing changes in capacitance.
  • Biosensor Technology: Advantages and Applications
    Article - 12 Nov 2013
    A biosensor is a biological detection system in which a biological component is combined with a transducer to perform measurement of a biochemical quantity. The development of biosensors started with...
  • Catadioptric Sensors for Computational Vision
    Article - 21 Nov 2013
    The traditional video camera with its limited field of view makes it difficult for use in some of the applications in the field of computational vision. Catadioptric sensors are proving to be an apt...
