Smart Wearable Devices-Your Life Partner
Good sports equipment can make us better when exercising. We can’t buy it without consideration. There are many smart wearable devices, sports bracelets, sports watches, etc. This article will help every consumer of Sports wearable devices.
1. Function Introduction of Intelligent Wearable Device
There is a “three-axis acceleration sensor” chip. The ordinary bracelets adopt the chip. The chip calculates the acceleration speed. It calculates the acting force. Then it calculates the direction and frequency of your travel. The body acceleration shows periodic changes in our motion state. The moving bracelet has its function. It will detect and record the peak and number of the waveform. Then it calculates the number of steps you walk in real time. The barycenter will fluctuate upward and downward when we walk.
The smart wearable device may not distinguish the shaking frequency. It is similar to the pace of walking. The smart wearable device will make a thorough judgment according to the map. To calculate the number of steps you walk.
2. Heart rhythm monitoring
These devices use heart rhythm monitoring as a selling point. Indeed, we should care about our heart rhythm when exercising. After all, it has something to do with life. For example, HONOR MagicWatch 2 can detect our heart rhythm in real time. We can see our physical condition and make adjustments.
There are three principles for heart rhythm monitoring. One is Photoelectric transmission measurement. Others are ECG signal measurement and arterial blood pressure measurement. The first is the most common. The equipment contacts the skin. Sensor will emit a light to hit the skin. Blood can absorb the wavelength of some special light. So every time the blood vessel beats, this wavelength can tell us the heartbeat.
ECG signal measurement can calculate the electrical signals. It measures the electrical signals of myocardial scaling. Its principle is similar to electrocardiogram. Its circuit is complex. Electromagnetic interference can interfere it . Its accuracy will decrease when measure irregular movements.
Arterial blood pressure measurement can capture the blood vibration changes. The change can be linked with heartbeat. It obtains heartbeat through model processing. Products as massagers adopt this method.
Smart wearable devices can detect body temperature. You needn’t look for a thermometer when you are ill. It can monitor the sleep status of the human body at night.
These devices can provide a lot of services and conveniences. In the future, the functions will be more perfect. It will become our essential “partner” in life.
