Abstract

Absorbent articles incorporating sensory element members are disclosed. The absorbent articles may be disposable pant like garments designed to assist urinary toilet training such as of young children. Upon urination by the wearer, the article produces a feedback response which is transmitted to the wearer by the sensory element member. Wetness based, temperature based and other feedback responses are disclosed. The feedback response should be immediate and unmistakable to the wearer and also be temporary and harmless.
