Photoelasticity can be explained as the change in a material’s optical properties when it undergoes mechanical deformation.
An accelerometer is a sensor used to measure the proper acceleration of an object, by calculating the displacement of mass.
A strain gauge is a device that shows variable electrical resistance when exposed to external forces or strain.
Sensors are devices that are used to sense/measure physical quantities. A sensors output is described with the help of certain terminologies that provide details of the quantity being measured.
Ionizing radiation is invisible to the naked eye. When it interacts with matter several events can take place, including the emission of charged particles and photons.
Recently, researchers from MIT have combined sensor technology with carbon nanotubes. Carbon nanotubes are hollow, cylindrical, one-nanometer structures made of pure carbon.
A capacitive sensor measurement system requires three components: a probe to detect any changes in distance to a target by sensing changes in capacitance.
Several applications including sensor design, chemical catalysis and therapeutics demand exploration of molecular recognition methods which involves biological macromolecules such as aptamers and antibodies.

Graphene has been widely employed for the fabrication of various sensors and other new devices because of their distinct properties and high performance range.
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 life cycles of many marine creatures.
