Cynophobics may soon be able to avoid the anxiety of being sniffed by the canine police at airports thanks to the development of a nanosensor by a team of researchers at the University of California, Berkeley. The new technology, which uses light based plasmon sensors, can identify the smallest and most difficult to detect explosives and so could be employed at airport security in the near future.

Resistors, thermocouples, and diodes are the commonly used temperature sensors for cryogenic applications.
The world’s population is rapidly expanding with a huge proportion of this growth found in our cities. The increased population and our modern life style are putting more pressure on the infrastructure within our cities. Researchers are now using sensor technology with the aim of making our cities more efficient.

It is uncommon to meet somebody in the developed world who doesn't own a cell phone these days, in fact there are almost as many cell phones in the world as humans. Smartphones, with the capability of internet access and built in applications, have become a useful tool to track information about the user. This information can include health, travel and hobbies and can give a fairly accurate representation of the personality of its owner.

With the fashion and technology industries becoming ever more entwined, some technology giants are looking to use fashion to not only give a visual statement, but also to help improve our lives and the lives of those around us. Recent examples include the ‘Up’ from Jawbone, Google Glass and now, Sony’s SmartWig.

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.
