This application claims the priority of the Chinese patent application with the application number 201710514246.4 and the title of the invention "A Wearable Tightness Detection Method for Wearable Devices" submitted to the China Patent Office on June 29, 2017, the entire contents of which are incorporated herein by reference In this application.

technical field

Background technique

The main advantage of wearable devices such as smart watches and bracelets is to monitor the user's health. For example, use the bracelet to monitor the number of exercise steps, heart rate, sleep index, etc. These smart wearable devices integrate many sensors to obtain the wearer's health. Sign data, record health status. Since pulse or heart rate is one of the important parameters of vital signs, heart rate measurement has become an essential function of smart wearable devices.

At present, the heart rate measurement of wearable devices is mainly through photoplethysmography (photoelectricplethysmography, PPG). PPG is a non-invasive detection method that uses photoelectric means to detect changes in blood volume in living tissue, and is a technology that uses light to measure pulse. That is, the photoelectric sensor is used to detect the difference in the intensity of reflected light absorbed by human blood and tissue, to trace the change of blood flow in the cardiac cycle, and to calculate the heart rate from the obtained pulse waveform. The structure of the photoelectric sensor shown in FIG. 1 , the photoelectric sensor may include a transmitter, a receiver, and the like. Wherein, the transmitter may be a light emitting diode, an infrared emitting diode, etc., and the receiver may include a phototransistor, etc. When the light emitted by the transmitter passes through the skin tissue and then reflects to the receiver, there is a certain degree of attenuation of the light. Changes in volumetric pulse and blood flow can be achieved through changes in light.

However, for wearable devices such as smart watches and bracelets, irregular wearing methods can affect the measurement of heart rate signals, such as light leakage caused by incomplete fit, arm swings, and smart watches or bracelets on the skin. Slight movement of the device will affect the measured heart rate signal. Wearing the smart watch or wristband too tightly, raising the arm and making a fist can also affect blood circulation, which may also affect the heart rate signal.

In the embodiment of the present application, the wearable device is taken as an example of a smart watch, and the smart watch is used to measure the wearer's heart rate for illustration.

Fig. 2 exemplarily shows a schematic diagram of smart watch wearing requirements in the prior art. As shown in the left picture in Figure 2, when the watch is worn too loosely, the watch will slide on the wrist due to the gap between the watch and the wrist, causing the sensor to fail to read the heart rate or accurately read the heart rate, as shown in Figure 3 Shown is the PPG signal measured when the watch is worn too loosely. It can be seen that the PPG signal has a sudden change. At this time, the user should try to tighten the watch strap a little. The right figure in Figure 2 shows an example of how to wear the watch correctly. The watch should fit comfortably on the wrist to ensure the stability of the measured PPG signal value, as shown in Figure 4 when the watch is worn correctly. The PPG signal value was stable without mutation.

In addition, when the watch is worn too tightly, it will also affect the accuracy of the watch for measuring heart rate.
