Your phone could soon get juiced over the air from a foot away. That’s thanks to the work of a new startup called Pi. Founded by two MIT graduates, it has developed a wireless charger that uses a honed version of inductive charging to send power further than previous versions of the technology.
Researchers at the Utah State University have tested an electric bus that charges wirelessly through induction and will revolutionize the transit industry. The technology was designed by Utah State University’s Wireless Power Transfer Team and the Utah Science Technology and Research Initiative’s Advanced Transportation Institute.
A wireless medical device can move through the bloodstream controlled by a magnetic field.
Eventually, implantable medical devices will be able to dispense drugs, get rid of blood clots and perform micro-surgeries inside our bodies. But powering these devices could be problematic. The point is to have minimally invasive gadgets keeping tabs on our health, cutting patients open to swap out their batteries is not an ideal situation. (Video)
