The new ultra-thin electric polymers can revolutionize sensor technology.

The new polymer is ultra-thin. And it conducts like metal. That can make a revolution in technology. There is needed very thin electric wires. The system can be more effective than using lathes. The polymer or so-called polymerase chain reaction can make it possible to create very thin wires. Those wires can work with systems like neuroimplanted microchips. 

Those microchips can be very thin systems on the skull. And then. The wires can pull through the skull to the brain. That kind of polymer system can make it possible to create a system that is below the skin. And can communicate with an electrode in the hat. 

The ultra-thin electric polymers can also make new steps to the sensor technology. Or they can create structures that can remove radar echoes. That kind of material can at the same time, detect the incoming radar impulse. The system can send that thing into the microchips that warn about the radar scanning. 

Then the system requires an energy dump. There that material can send an electric signal. The thin polymer can also be used in spaceborne radar systems. Those long polymer fibers can rotate under satellite and they can scan areas very carefully. 

The new, very advanced radar systems can detect stealth aircraft. Using so-called indirect observation. The indirect observation means that even if radar cannot see the aircraft. That can have so-called "chameleon camouflage". That camouflage makes the aircraft transparent. 

The lidar or radar systems can still detect the aircraft benefiting the movements of the air molecules. The limit of the lidar system is it's quite easy to jam by using fog or smoke. The radio waves travel through those things and they can detect pressure waves that aircraft forms when it travels through the air.

Those new systems can make new types of submarine detection systems possible. The new systems can use the Kelvin waves. Or Kelvin wake patterns to detect nuclear submarines. 

"The team focused on studying the impact of Kelvin wake, a V-shaped wave pattern created by submarines or other ships while sailing. The waveforms are at a consistent angle due to the interaction of transverse and divergent waves."(Interesting Engineering, China could detect US’ stealth submarines with new tech that tracks surface disturbance)

"A Kelvin wave (fluid dynamics) is a long scale perturbation mode of a vortex in superfluid dynamics; in terms of the meteorological or oceanographical derivation, one may assume that the meridional velocity component vanishes (i.e. there is no flow in the north–south direction, thus making the momentum and continuity equations much simpler). This wave is named after the discoverer, Lord Kelvin (1879)." (Wikipedia, Kelvin wave)

"Kelvin wake creates a detectable magnetic field. Chinese researchers revealed that Kelvin's wake created a faint but detectable magnetic field. It’s generated as seawater ions interact with the Earth’s geomagnetic field after being disturbed by the submarine’s motion." (Interesting Engineering, China could detect US’ stealth submarines with new tech that tracks surface disturbance)

"Using numerical simulations, the researchers quantified how these magnetic signatures vary with a submarine’s speed, depth, and size. For example, increasing speed by 2.5 meters per second (8.2 feet per second) boosts magnetic intensity tenfold; reducing the depth by 20 meters (66 feet) doubles the field strength; and longer submarines produce weaker fields, while wider hulls amplify them reported SCMP."

The object that is in the water distorts the behavior of the water molecules. When something disturbs the water molecule it causes changes in the Kelvin waves, or Kelvin wake patterns. And that is one way to detect stealth submarines. The problem is how to measure the Kelvin fields. That thing requires very advanced scanners.
