Abstract
Adhesion between carbon nanotube (CNT) arrays is measured and characterized for number of different contact areas. The CNT arrays are directly grown on an electrostatic microactuator, and they make contact with each other during the growth process. The pull-out force is precisely applied by the microactuator while the contact status is identified by measuring electrical resistance between the CNT arrays. We have designed different contact areas of 1000, 6000, and 8500 ${\mu}m^2$ between the CNT arrays, and the corresponding adhesion increases from 0.9 to 3.7 ${\mu}N$ as the contact area increases.
