Nonwoven webs/nonwoven laminates for use in absorbent articles are disclosed. The nonwoven laminate includes a first nonwoven web with continuous spunbond crimped fibers and a second web joined to the first nonwoven web. A plurality of apertures extend through at least one of the first nonwoven web or the second web. The nonwoven web includes a plurality of continuous spunbond crimped fibers wherein a plurality of apertures extend through the nonwoven web.

An absorbent structure, including a sensor system, can sense and measure the level of wetness contained within the absorbent structure as well as sense and measure environmental conditions. The sensor system may include passive RFID sensors or tags, RFID readers, antenna, a tuning module, a processing module, a memory module and a wireless communication module. The absorbent structure may further include two or more sensors, with a first sensor placed in a first area most likely to first be exposed to liquid and a second sensor spaced apart from the first sensor in an area likely to be exposed to liquid only after the absorbent structure has become more saturated.
