Diaper sensors and moisture detection sensors include systems that detect various structures and configurations, such as voltage detection, IC tag detection, current increase / decrease detection, and frequency shift detection. However, due to high costs and poor workability, it is not possible to meet demand.
The present invention relates to a diaper sensor and a moisture detection sensor characterized by low cost, practical, workability and economy from the standpoint of a user or a caregiver at the site.

Problems to be solved by the invention

  Conventional moisture detection sensors have difficulties in shape, flexibility, workability, etc. for mounting on objects such as diapers. The product is particularly expensive, and the diaper sensor has disadvantages such as uncomfortableness and discomfort to the user's skin, inconvenience of installation and replacement, and lower overall work costs such as reduced work efficiency and disposal. there were.

  By improving the shortcomings of the conventional diaper sensors mentioned above, it is possible to manage the health of users by promptly detecting and reporting leakage of excrement such as baby and users with a convenient diaper sensor with low cost and high work efficiency. It is an object of the present invention to provide a diaper sensor and a moisture detection sensor suitable for nursing use for suppressing disease.

Means for solving the problem

  The diaper sensor and the moisture detection sensor are attached in parallel with a 1 mm gap between two strips of carbon chopped paper electrode (2) and carbon chopped paper electrode (3) on Japanese paper (1). The structure is covered with Japanese paper (4).

Moisture is detected by short-circuiting (contacting) the water-absorbing Japanese paper (1) and carbon chopped paper electrodes (2) and (3) constructed by the above-described structure by the action of slight moisture (urine leakage).

The above-mentioned carbon chopped paper electrode is a sheet of carbon fiber kneaded in Japanese paper with a thickness of about 0.1 mm that has durability, safety and flexibility, and is a thin, tough and light material suitable for the application. Since it can be freely designed, it is suitable for detecting moisture for preventing water leakage of complex structures. In particular, a diaper sensor, which is a care product, can be easily attached to a diaper, and can be used as a convenient disposable diaper sensor paper by eliminating discomfort and discomfort to the skin.

By using the above-mentioned carbon chopped paper electrode, the connection between the sensor unit and the reporting device unit can be easily detached, and the power supply battery and reporting device can be made compact so that it can be attached to the user's diaper. However, it is desirable to adopt a configuration that does not impose a burden.

The diaper sensor and moisture detection sensor of the present invention is a low-cost product that has an extremely simple structure as described above, has low production costs such as materials, assembly, and processing costs, and has excellent durability, safety, and flexibility. It becomes a diaper sensor and a moisture detection sensor which can respond to uses such as moisture detection for preventing water leakage of diapers and other objects.

Embodiment of the Invention

Embodiments of a diaper sensor and a moisture detection sensor of the present invention will be described in detail with reference to the drawings. FIG. 1 is a cross-sectional view and a plan view of a diaper sensor and a moisture detection sensor.
Diaper sensor and moisture detection sensor are Japanese paper (1) (width 40mm, length 550mm, thickness 0.5mm) on carbon chopped paper electrode (2) (width 5-10mm, length 600mm, thickness 0.3mm) Grade) and carbon chopped paper electrode (3) (width 5 to 10 mm, length 600 mm, thickness 0.3 mm) between the two strip-shaped electrodes, about 1 mm is opened and adhered in parallel, and the electrodes are attached to Japanese paper ▲ 4 ▼ (width 40 mm, length 550 mm, thickness 0.5 mm) is covered.
For this electrode, carbon chopped paper with carbon fiber cut shortly and kneaded into Japanese paper is a conductive substance, manufactured in a mesh shape of 3 mm mesh or less, and is used as a heating element with a thickness of about 0.1 mm. However, it is made of a thin, tough material that can be freely designed in addition to flexibility and durability.
The carbon chopped paper electrode can be provided with a structure that can accommodate a wide range of areas and distances by forming a plurality of two strip-shaped electrodes as shown in FIG.
By using Japanese paper having water absorption and durability as the material for wrapping the electrodes, it becomes possible to short-circuit (contact) the electrodes even with a slight amount of moisture.
Structures such as the sensor unit (about 30 mm wide, about 600 mm long, about 0.3 mm) and the reporting unit (about 10 mm high, 20 mm wide, about 40 mm long) are simple and compact, and the storage case is on the skin. It is desirable to use safe materials.
Since the sensor part is flexible, it is directly attached to the object with tape or the like. In addition, the reporting device unit is integrated with a device that is connected with two strip electrodes sandwiched between it and a case that houses the reporting device with a structure that can be easily attached and detached. It is desirable to do.

The invention's effect

Carbon chopped paper is used as an electrode, and the outer periphery of the two strip-shaped electrodes is wrapped with Japanese paper. The water is short-circuited (contacted) between the electrodes and the Japanese paper covering the outer periphery with slight water. The structure to detect.
The diaper sensor and the moisture detection sensor are characterized by detecting moisture by moisture action, and the constituent materials are low in production cost such as material cost and processing cost, and are thin, tough, durable, safe, flexible, Utilizing superior features such as water absorption and free design, eliminate problems such as diaper wearing work efficiency, skin discomfort and disposal pollution, and build low-cost sensors and low-cost notification devices By doing so, a cheap disposable diaper sensor having a function as a diaper sensor has an effect of suppressing health care and illness.
