Description

A patch type sensor module capable of multi-sensing {patch type sensor module}

The present invention relates to a patch-type sensor module, and more particularly, to a patch-type sensor module capable of multi-sensing capable of acquiring various biometric information of a user.

Generally, there are a contact type and a non-contact type thermometer for measuring the body temperature and heart rate of the body. Examples of the general thermometer include mercury, alcohol, and an infrared ray sensor.

Such a thermometer can be measured only after a certain period of time in the state of being worn or in contact with the body.

Accordingly, in the case of infants, infants, and patients whose mobility is uncomfortable, it is troublesome for the person around him to measure the body temperature since it is necessary to help the person keep the thermometer on the patient's body.

In addition, since the conventional thermometer is a method of contacting the subject's body for a certain period of time and then separating the body from the user's body to check the body temperature, there is an inconvenience in real-time or periodic verification.

In addition, since the conventional thermometer can measure only the body temperature, there is a problem that measurement can be performed through a separate sensor or equipment in order to acquire other information from the subject.
