What are the components of a robot that could be produced through inkjet printing employing flexonics and organic semiconducting polymers? Certainly, it would include electronic circuits (including transistors, diodes and resistors). Inkjet printers have also been employed to print batteries, RFID chips (for radio identification tags), organic light-emitting diode (OLED) display screens and electro-actuated polymers used as artificial muscles.
Gregory Daigle has written a fascinating article on how "advances in inkjet technology forecast robotic origami", including the butterfly-bots pictured above.
If 2-D inkjet printing could enable these creations and more, imagine what will be possible with desktop manufacturing on your personal nanofactory!
