Utilizing Carbon Nanotubes in Thin-Film Flexible Electronics

1:40 PM - 2:05 PM
The Lockheed Martin Advanced Technology Center is actively developing flexible electronics to enable and enhance applications by utilizing the large-area, lightweight, and conformal attributes of the technology. Both passive and active thin-film electronics, including gas and electro-optic sensors, logic circuits, memory, advanced packaging, and active-matrix arrays with integrated row and column drivers, have been fabricated on polyimide films. The NMOS circuits are comprised of enhancement-mode metal oxide thin-film transistors and carbon nanotube fabric resistive elements. The flexible circuits are capable of low-voltage operation (1.5V) and have shown good radiation tolerance and thermal stability (>100C operation and >200C survivability in air). Nanomaterials have been incorporated into flexible electronic circuits as both active (e.g. non-volatile memory and sensors) and passive (e.g. resistive traces and ESD protection) elements. They have been used to tailor thin-film and device properties including resistivity, Temperature Coefficient of Resistance (TCR), absorption, thermal conductivity, and gas sensor sensitivity/selectivity.
