The present invention provides a personal hygiene item. In simple terms, one of the main features of the present invention is to provide a low-cost personal hygiene item capable of providing a multi-component detection function. The personal hygiene item of the present invention mainly comprises a first material layer and a second material layer. The first material layer is made of hydrophobic material, and the second material layer is disposed thereon. Also, the second material layer comprises a discolored portion. In actual practice, a fluid under test contacts with the corresponding discolored portions via the hydrophobic layer of second material layer for a color changing reaction. Meanwhile, since the hydrophilic performance of the discolored portion is better than the hydrophilic performance of the hydrophilic layer, the back permeation of the fluid under test can herein be prevented.

Personal hygiene item

The present invention provides a fiber base sensor and the fabricating method thereof. More specifically, one of the main goals of the present invention is to solve the problem existing in the prior art of the failure of forming a plurality of nano-particles on the surface of the fiber base sensor evenly by utilizing self-assembly process with the nano-imprint process. Furthermore, the another goal of the present invention is to provide detail parameters required in the said nano-imprinting process for avoiding the efficiency drop caused by over-embedding the nano-particles into the fiber based sensor.
