In the end, a reporter has to leave a note in his campus pigeonhole. The elusive Friend is the unlikely instigator of what may be a revolution in electronics: plastics. (46) Although most electronic devices make use of silicon chips, Friend sees a future in which mobile phones, TVs, watches, computers and other devices incorporate inexpensive plastic chips.
(47) Friend’s vision is based on his own discoveries, back in the ’80s and ’9Os, that plastics can be used to make transistors, the basic element of chips, and light-emitting diodes (LEDs), which glow when electricity passes through them. His work has already yielded a new generation of lighter, thinner, brighter, cheaper and more flexible electronic screens for everything from lightweight mobile phones to disposable "talking" electronic greetin
