Anisotropic carbon nanotube for new type of angle sensor development

Vertically Aligned Carbon Nanotubes (VACNTs) has captured attention by the researchers because of their flexibility and other attractive engineering properties. They are promising to be used as a functional bulk material in MEMS as well [1]. VACNT array (CNT forest) is known to be the darkest mat...
