Self-Healing Electronics Could Reduce Waste

When one circuit within an integrated chip cracks or fails, the whole chip – or even the whole device – is a loss. University of Illinois engineers have now developed a self-healing system that restores electrical conductivity to a cracked circuit in less time than it takes to blink.

Fully Printed Carbon Nanotube Transistor Circuits for Displays

Organic light-emitting diode (OLED)-based displays are used in cell phones, digital cameras, and other portable devices. But developing a lower-cost method for mass-producing such displays has been complicated by the difficulties of incorporating thin-film transistors that use amorphous silicon and polysilicon into the production process.
