Abstract
Resistive elements include a patterned region of nanofabric having a predetermined area, where the nanofabric has a selected sheet resistance; and first and second electrical contacts contacting the patterned region of nanofabric and in spaced relation to each other. The resistance of the element between the first and second electrical contacts is determined by the selected sheet resistance of the nanofabric, the area of nanofabric, and the spaced relation of the first and second electrical contacts. The bulk resistance is tunable.
Claims14
A resistive element, comprising:
- a patterned region of nanofabric with a predefined area and a pre-selected sheet resistance, the nanofabric having a pre-selected temperature coefficient of resistance (TCR);
- and
- first and second electrical contacts contacting the patterned region of nanofabric and in spaced relation to each other,
- wherein a total resistance of the resistive element between the first and second electrical contacts is determined at least by the contact resistance between the patterned region of nanofabric and each of the first and second electrical contacts, the pre-selected TCR of the nanofabric, and by the resistance of the patterned region of nanofabric;
- and
- wherein the total resistance of the resistive element is tunable to a pre-selected total resistance.
