The State of the Transistor in 3 Charts

Cars That Think

Here is a small sampling of what transistors have become in the last 75 years: Ephemeral: Researchers in Illinois developed circuits that dissolve in the body using a combination of ultrathin silicon membranes, magnesium conductors, and magnesium oxide insulators. Five minutes in water was enough to turn the first generation to mush.
