Stanford University engineers have developed a wireless, self-propelled device, able to be controlled through the bloodstream via an external, handheld transmitter. The device can be used to deliver a payload of drugs to a targeted area, and is powered wirelessly using electromagnetic waves from the transmitter, which is held over the body to guide it.
The device is only 2 square millimeters.
