Jet-Injected Drugs That Feel Like A Mosquito Bite
Soon we won’t need hypodermic needles. This device delivers a high-velocity jet of liquid that breaches the skin at the speed of sound:
[T]he MIT team, led by Ian Hunter, the George N. Hatsopoulos Professor of Mechanical Engineering, has engineered a jet-injection system that delivers a range of doses to variable depths in a highly controlled manner. The design is built around a mechanism called a Lorentz-force actuator — a small, powerful magnet surrounded by a coil of wire that’s attached to a piston inside a drug ampoule. When current is applied, it interacts with the magnetic field to produce a force that pushes the piston forward, ejecting the drug at very high pressure and velocity (almost the speed of sound in air) out through the ampoule’s nozzle — an opening as wide as a mosquito’s proboscis.

Didn’t I read about this concept in Popular Mechanics magazine along with the video telephone?
This is way cool. I think of similar medical devices on Star Trek.
This looks like the device used to inject the swine flu vaccine in 197? It left my kids rolling on the floor holding their arms and wailing. I didn’t much like it, either. It was definitely worse than a mosquito bite!
Probably not the same device.
