Wearable device

The present invention relates to a wearable device, and more particularly to a wearable device that uses a piezoelectrically actuated micro gas pump to sense physiological information.

In today's society where fast and personal pressure is growing, the awareness of the pursuit of personal health is gradually evolving. It is the general person who wants to constantly monitor or examine his or her health. In general, traditional data measurement of human physiological health information is mainly through a fixed sphygmomanometer or a large-scale detection instrument, which usually includes a motor-type gas pump, an airbag bag, a sensor, and a deflated gas. Valves, batteries, etc., in which a motor-type gas pump is prone to frictional losses, and the components are bulky after assembly, and do not utilize frequent use, but if a smaller-sized motor-type gas pump is used , it will lose faster and consume more energy.

In order to facilitate the average person to regularly monitor their own health conditions and make the monitoring device easy to carry, the wearable health monitoring devices on the market are increasing day by day. However, in the case of the commonly-used wearable health monitoring device on the market, it is usually detected by optical detection. However, the accuracy of the optical detection method is not high, so the error value is often generated, and cannot be Effectively obtain trusted data, so that users can not obtain accurate data related to their own health, and it is easy to cause errors in judgment. On the other hand, if you choose a more accurate detection method, although the error value is relatively small and the data is obtained correctly, the time taken for relatively accurate detection is longer.

Generally speaking, in order to sense the physiological information of a person to be tested, it is usually selected as shown in FIG. 1 such as the head 1a, the heart part 1b, the wrist 1c or the ankle 1d, and the positions are monitored. The most sensitive location in the human body such as pulse blood pressure and heartbeat is to quickly and effectively understand the physiological health information of the person to be tested by sensing at these locations. However, as mentioned above, if the wearable health monitoring device with optical detection is not accurate due to its low accuracy, it is difficult to identify the data detected by it. High blood pressure monitors or other measuring instruments are too small to be light, thin, and portable, and the measuring instruments take a long time to detect, such as users. It is necessary to immediately know the physiological health information, but it is inconvenient to use.
