ABSTRACT

Systems and methods are provided for monitoring properties of a web during a
roll-to-roll manufacturing process. The methods may include moving the web
past a first roller such that the web contacts the first roller, wherein the
first roller includes a first contact strip formed of an electrically
conductive material and extends circumferentially about the first roller,
applying a voltage to the first contact strip while moving the web past the
first roller, such that the voltage conducts through the web to a second
contact strip, measuring the voltage received by the second contact strip,
determining local resistance values relative to positions of the web based on
the difference in the voltage applied to the first contact strip and the
voltage received by the second contact strip, and determining at least one
property of the web relative to the positions of the web based on the local
resistance values.
