We need them because thin, pliable organic semiconductors are too slow to serve in tomorrow’s 3‑D chips
Imagine rising from bed to catch an early flight. As you head for the shower, still groggy, a tiny, flexible sensor chip in yesterday’s clothes reminds you that they need to be washed. At breakfast, you check on your flight status and then stream the latest news to a tablet-size flexible display, flipping through pages of text and video. A message from your doctor pops up, reminding you to wear your medical diagnostic patch and pack your medication. As you leave your house, tiny sensors in the carpet and wallpaper put some appliances into standby mode. At the airport, a flexible electronic ticket guides you to the right gate, and a wireless interface between your ticket, your passport, and a retinal scanner gives you immediate clearance.
