Researchers at Wake Forest University have created something which could change the way that smartphones and tablet devices are charged. Called Power Felt, this newly invented fabric is composed of tiny carbon nanotubes locked into flexible plastic fibers. These fibers are able to use temperature differences to create a large enough charge to power up a smartphone.
Recently, a Stanford engineer, Ada Poon, lead a project which has created tiny robotic medical devices that are powered by wireless technology. According to Stanford University, the implantable machines are small enough to easily move through veins. These injectable nanobots can carry out medical tasks, gather diagnostics and even deliver drugs into the bloodstream.
