Abstract

The present invention provides a diaper including a body, a sensing module disposed on the body for detecting humidity of the body and wirelessly transmitting an electrical signal converted from the humidity and a receiving module for receiving the electrical signal transmitted by the sensing module and generating an alarm signal.

Claims

1. A diaper, comprising:

a body;

a sensing module disposed on said body for detecting humidity of said body and wirelessly transmitting an electrical signal converted from the humidity; and

a receiving module for receiving said electrical signal transmitted by said sensing module and accordingly generating a warning signal.

2. The diaper as claimed in claim 1, wherein said sensing module comprises a humidity sensing element, a signal processor, a micro power supply and a signal transmitter.

3. The diaper as claimed in claim 1, wherein said sensing module is disposed on a flexible circuit board comprising a polyimide film (PI).

4. The diaper as claimed in claim 1, wherein said sensing module is disposed on a flexible circuit board, and said flexible circuit board comprising a polyester film (PET).

5. The diaper as claimed in claim 1, wherein said sensing module is a disposable sensing module.

6. The diaper as claimed in claim 1, wherein said sensing module is a reusable sensing module.

7. The diaper as claimed in claim 2, wherein the material of said humidity sensing element is polymer material.

8. The diaper as claimed in claim 2, wherein said micro power supply is a micro battery cell.

9. The diaper as claimed in claim 2, wherein said micro power supply is a flexible battery cell.

10. The diaper as claimed in claim 2, wherein said signal transmitter is a micro antenna for transmitting wireless signal.

11. The diaper as claimed in claim 10, wherein the signal frequency of said micro antenna is 125-134 kHz.

12. The diaper as claimed in claim 10, wherein the signal frequency of said micro antenna is 13.56 MHz.

13. The diaper as claimed in claim 10, wherein the signal frequency of said micro antenna is 400-900 MHz.

14. The diaper as claimed in claim 10, wherein the signal frequency of said micro antenna is 2.45 GHz.

15. The diaper as claimed in claim 10, wherein the signal frequency of said micro antenna is 5.8 GHz.

16. The diaper as claimed in claim 2, wherein said signal transmitter is a micro speaker.

17. The diaper as claimed in claim 1, wherein said receiving module includes an alarm for giving a caution by whistling, lighting, or glittering to inform changing the diaper.

18. The diaper as claimed in claim 1, wherein said receiving module is a mobile device.

19. A diaper, comprising:

a body;

a sensing module disposed on said body for detecting humidity of said body and wirelessly transmitting an electrical signal converted from the humidity; and

a transmitting/receiving module for providing power to said sensing module coupled with said transmitting/receiving module to generate a induction current, and receiving an electric signal from said transmitting/receiving module to send a warning signal.

20. The diaper as claimed in claim 19, wherein said sensing module includes a humidity sensing element, a signal processor, and a sensor.

21. The diaper as claimed in claim 19, wherein said sensing module is disposed on a flexible circuit board comprising a polyimide film (PI).

22. The diaper as claimed in claim 19, wherein said sensing module is disposed on a flexible circuit board comprising a polyester film (PET).

23. The diaper as claimed in claim 19, wherein said sensing module is a disposable sensing module.

24. The diaper as claimed in claim 19, wherein said sensing module is a reusable sensing module.

25. The diaper as claimed in claim 20, wherein the material of said humidity sensing element is polymer material.

26. The diaper as claimed in claim 19, wherein said receiving module includes an alarm for giving a caution by whistling, lighting, or glittering to informing changing the diaper.

27. The diaper as claimed in claim 19, wherein said receiving module is a fixed device.
