Abstract
The present invention provides a humidity sensor, comprising a substrate having a coating wire and at least one humidity detecting portion S, each humidity detecting portion S comprises at least two electrodes, and each of electrodes is connected to their respective coating wires, and an electrochemical medium which is electrically insulated when dry and conductive when wet is provided between electrodes. This kind of humidity sensors can be used to monitor humidity in a highly sensitive manner, especially monitor the amount and extent of urine.
Claims20
A humidity sensor, comprising:
- a non-electrically conductive substrate having a coating wire and at least one humidity detecting portion S, each humidity detecting portion S comprises at least two electrodes, and each of the electrodes is connected to their respective coating wires, wherein an electrochemical medium which is electrically insulated when dry and is conductive when wet is provided between the two electrodes, and
- wherein the humidity detecting portion S further comprises a moisture absorbing hole that is disposed between the two electrodes;
- two electrically conductive carbon adhesive layers covering the two electrodes separately so that the two electrodes are spaced apart from each other across the two carbon adhesive layers, and the electrochemical medium is filled in the moisture absorbing hole;
- and wherein the electrochemical medium comprises a packing portion and a span portion, the packing portion is packed in the moisture absorbing hole and is adjacent to one side of the two carbon adhesive layers, the span portion extends on the carbon adhesive layer while spanning two carbon adhesive layers and being adjacent to the other side of two carbon adhesive layers.
