Teo, you say very stupid things. Everybody does, or should know, quantum electrodynamics is the governing theory on how electronics work. At least Geoff makes me laugh.
Right.

Teaming up with Michael Dickey at North Carolina State University, they recently discovered that liquid metal electronics are not only useful for stretchable circuit wiring but can also be used to make electrical switches. These fluidic transistors work by opening and closing the connection between two liquid metal droplets. When a voltage drop is applied in one direction, the droplets move towards each other and coalesce to form a metallic bridge for conducting electricity. When voltage is applied in a different direction, the droplets spontaneously break apart and turn the switch to open. By quickly alternating between an open and closed and open switch state with only a small amount of voltage, the researchers were able to mimic the properties of a conventional transistor.
Any questions?
