A company called Micromem is trying to develop some new kind of sensors that are based on something we are all familiar with: magnetics. 

This technology, also known as Magnetic Random Access Memory, or MRAM, is planned to revolutionize sensor technology.  MRAM allows the user to see anything’s unique magnetic signature, very similar to the technology used in magnetic resonance imaging (MRI) of most hospitals. 

Micromem believes that there are many applications of this new technology, such as biometrics, with an ability to see beyond fingerprinting.  Additional uses include medical devices including sensors for blood sugar levels, as well as some new applications for defense and security. 

Apparently, MRAM is perfect for explosive device detection and even more advanced metal detectors.  It can also “see” certain samples for drilling, mining, or production, so it is an efficient tool for the exploration of natural resources.  Right now, there is no projected date as far as when this MRAM will be out, but it can change the world as we know it.
