How about magnetic sensors embedded in your skin?

Magnetic sensor that gives you added perception of directional sense

We humans have become so advanced in technology that it is only time before we can mimic all living things in robotics form. But what we lack is certain things that only some animal species have. For example, the ability to sense magnetic fields which helps them in getting a sense of direction during long migrating stints. Sharks, birds and insects can orient themselves in the right direction by sensing the magnetic fields of earth which gives them accurate perception of altitude and direction. Experts call it magnetoception as it gives a unique sense of perception governed by magnetic field.

e-whiskers developed for robotics and wearable technology applications

electronic whiskers

Nanotechnology and artificial body parts have been a subject of research for intuitive minds for decades and with the kind of technology that the world has evolved it is no surprise that we are seeing new developments every now and then. Researchers at Berkeley Lab and University of California (UC) Berkeley have come up with artificial whiskers made from silver nanoparticles and composite films of carbon quite similar to the whiskers of cats or rats. These e-whiskers are very sensitive to even a pressure of 1 Pascal which is equivalent to pressure exerted by a dollar bill on table. These electronic whiskers have high-aspect ratio fibers coated with conductive composite films of nanotubes and nanoparticles making them 10 times more sensitive to pressure than other pressure sensors developed in the past.

Invisibility cloak technology that makes you vanish in thin air

Invisibility cloak

We as humans have always fantasized about getting invisible and not only in movies but in reality too intuitive minds have stretched the limitations of physical science using materials like Quantum Stealth to demonstrate how one can become invisible to the eye. Taking a step further US physicists headed by Professor David Smith have invented an invisibility cloak made from a very thin electronic system that works on a completely new concept and design. The system uses non-foster negatively capacitive metasurfaces that are tuned for active frequency that prevents scattering of light in microwave range. The technology focuses on minimizing the global scattering signature of an object using thin superconducting shells.
