Using Terahetz waves can be more powerfull that x-rays and microscopes.THz waves are already in actions for years, it is already used in new 3D scanners seen in airports but using the technology on practical applications is not that avisable 'cause sensors used are too bulky.

But thank to a four year project called TeraNova, Quantum Cascade lasers semiconductor devices was developed which take advantage of quantum effects to operate at frequencies in the range of THz. These development will surely make new breed of sensors for different application like in medicine and electronics. More details about THz on the link below.

Sensors that detect your intent

A piece of metal can mean something, or something else. This is why I have never believed in the power of metal detectors in airports.

Now, researchers are taking security to an even higher level by creating detectors that claim to find out if you had the intention to harm, based on your unconscious reaction to stimuli.

Now, will this work against terrorists? We can only see.

Thin Film Battery Technology Milestone

Various innovations in the technology and engineering is continually being push through to provide man's work more convenient, efficient, and clean. A latest milestone is the improvement of power storages in the form of thin film batteries. This battery technology surpasses the previous technology of the lithium and classic AA and AAA batteries. It is packed with cool and multi-functional features which can be seen here:
