Humidity detection device for smart diaper

Abstract

A humidity detecting device includes a substrate, a humidity sensor mounted on the substrate, a vent mounted to the humidity sensor, wherein the vent is configured to guide moisture and air from interior of a sample to the humidity sensor, and a spike fixedly coupled to the humidity sensor. The spike can penetrate and hook to the sample, which attaches the humidity sensor to the sample.

Description

BACKGROUND OF THE INVENTION[0001]The invention relates to the technical field of wearable devices, and in particular, to a smart diaper having intelligent sensors.[0002]In the conventional technologies, there are often products that need to detect their humidity. Take diaper as an example, especially if the elderly diaper is not wet, the caregiver often needs to check the status of the diaper in order to avoid the user from using the comfort in time.[0003]In order to facilitate the humidity detection, a humidity detection device is generally used to detect the state of the diaper. At present, the humidity detection device has a Velcro patch (HOOK surface). The moisture detecting device is fixed by affixing the Velcro patch to the surface of the diaper. When the diaper needs to be replaced, the Velcro is torn apart and removed from the wet surface of the diaper. The humidity detection device is then fixed on the replaced diaper.[0004]However, the humidity detection device and the dia...

AI Technical Summary

Benefits of technology

[0008]In view of the above, the invention provides a humidity detection device, which improves detection accuracy and attachment stability.

[0018]As can be seen from the above technical solution, the humidity detection device provided by the present invention passes through a window and the humidity sensor passes through the window, so that the solid part of the Velcro patch is wrapped around the humidity sensor. The microenvironment of the humidity sensor is isolated from the outside air. The humidity sensor can only detect humidity through its detection end, which improves detection accuracy. The surface of the first lamination layer away from the second lamination layer is directly attached to the sample without being affected by the surface structure of the sample. The restrictions effectively increase the attachment stability between the humidity detection device and the sample.

Problems solved by technology

During usage, the diaper twists and moves along with the movement of the user's body, which easily brings outside air between the Velcro and the diaper to reach the humidity sensor in the humidity detection device, which affects the accuracy of the detection.

Moreover, the Velcro cannot be affixed to the smooth surface of the diaper.

The outside air can easily enter between Velcro and the diaper, the surface of the diaper is not easily moisturized and Velcro can separate from each other, causing the humidity detection device to fall off, which affects the detection accuracy.

The attachment between the humidity detection device and the diaper is not reliable.

However, to tear the adhesive from diaper surface might break the diaper surface.

However, the outside surface of most adult diapers is insulator, and humidity detection device cannot detect the moisture inside the diaper by just attaching to the diaper outside surface.

Therefore, the detection accuracy and the attachment stability have become a problem for humidity detection devices.
