Abstract
Contacts of an electrical device can be made of carbon nanotube columns. Contact tips can be disposed at ends of the columns. The contact tips can be made of an electrically conductive paste applied to the ends of the columns and cured (e.g., hardened). The paste can be applied, cured, and/or otherwise treated to make the contact tips in desired shapes. The carbon nanotube columns can be encapsulated in an elastic material that can impart the dominant mechanical characteristics, such as spring characteristics, to the contacts. The contacts can be electrically conductive and can be utilized to make pressure-based electrical connections with electrical terminals or other contact structures of another device.
