Abstract: A method for monitoring the surface of a device to physical and/or environmental exposure, the method comprising: • (a) attaching at least one sensor including a reactance autotuning integrated circuit to a surface of a device; • (b) attaching a reader in proximity to the sensor; • (c) measuring a reference reactance of the sensor with the reader at a selected frequency; • (d) continually monitoring for changes in the reactance of the sensor at the selected frequency, wherein changes to the reactance are digitized by the autotuning circuit; and • (e) comparing differences between the reference reactance and changes to the monitored reactance to determine if said surface of the device has been subjected to physical and/or environmental exposure.

Abstract: The present invention relates to an activatable zero strain composite laminate web comprising an activatable elastic laminate web having an elastic core layer and at least one skin layer which is less elastic than the core layer, and at least one pre-bonded staple fiber nonwoven web which is attached to one of the skin layers of the elastic laminate web, the at least one staple fiber nonwoven web having an elongation at break of at least 100% in the cross-direction and said activatable elastic laminate web forming an essentially homogeneous microtextured surface when stretched in the first upload in the cross-direction past the elastic limit of the one or more skin layers.
