Freestanding, substrate‐free organic field‐effect transistors and organic circuits with a nominal thickness of 320 nm are demonstrated by using a simple water‐floatation method. The devices work well in freestanding status, attached on banknotes, or bent over the blade of a knife. The ultralight devices with extreme bending stability indicate a bright future for organic electronics.
