Carbon nanotubes exhibit characteristics of resistor–capacitor–inductor in alternating current field and quality factor is estimated to be as high as 1 × 104. This value can be optically promoted and improvement is verified as a result of photocurrent creation in tubes. Experimental data is supported by ab-initio calculations.
A novel approach for a piezoelectric generator is presented. By coating ZnO on carbon nanotubes, the piezoelectric properties of ZnO are integrated with the structure flexibility and enhanced conductivity of carbon nanotubes. With suitable arrangement, the devices generate high voltage and current signals.
This study presents a novel process to batch-fabricated carbon nanotube devices on flexible substrate. In short, the pre-made carbon nanotube (CNT) arrays on Si-wafer are firstly blended with polymer and are then transferred onto a polymer film using chemical-vapor-deposition (CVD) of parylene. This yields CNT arrays on flexible substrates. Electrical measurements reveal that nanotube arrays behave...
This study employed the composite-film to fabricate CNT-polymer microactuators. The actuator is driven using electrostatic, thermal, and optical approaches. The subsequent measurements show that micro-cantilever actuators can be electrically driven at very low pull in voltage compared with existing MEMS elements. Bimorph effect from composite cantilever is also tested. The experimental results show...
