MIT, jet injector

The Massachusetts Institute of Technology
Developer of: A next-generation, needle-free drug device
Cool factor: Scientists at MIT have come up with a jet-injection device that blasts a drug through the skin without any needles. Other devices in the space are already in the marketplace, but MIT took its updated approach to a whole new level, making it sensitive enough to deliver doses at different depths, so young children and adults can use the device in equal measure. The device contains a powerful magnet surrounded by a wire coil that is attached to a piston. Add a current to the metal and a magnetic field erupts, firing the piston. The device then shoots the drug through its tiny nozzle and into the skin, almost at the speed of sound.
