Smart Watches

Why using smart watches turn to be a trend?

Smartwatches will become popular, mainly due to the development of technology and people's actual needs. Just as the emergence of watches, the human need for convenient time control at any time for the emergence of watches to create rationality, quartz watch and electronic watch to solve the emergence of a large number of watches popular technical problems, the First World War for the popularity of watches provided social conditions.

From the perspective of technological development, the development of sensors, chip technology, etc., make it possible to watch intelligent. Sensors assume the main responsibility of signal collection, among which the acceleration sensor is responsible for collecting data of daily activities. By analyzing the change of position data collected by the acceleration sensor, the smartwatch can calculate and analyze the user's activity records. Optical sensors are mainly used to monitor heart rate, blood oxygen and other health indicators.

The chip determines the smartwatch's computing speed and overall power consumption. As the health monitoring functions of smartwatches become heavier and heavier, the power consumption will also increase, and the optimization of chips can achieve a better balance between performance and power consumption of smartwatches.

From a demand perspective, health features are now one of the most important factors influencing consumers' choice of smartwatch. According to a survey conducted by Global Market Monitor in 2021, health monitoring is far more important than calling, video and location among many functions of smartwatches, and more than 70% of potential consumers give priority to the integrity of health monitoring when buying smartwatches.

The trend towards intelligent devices has led to the need for a key to effectively control these smart devices. Smart watches that not only have the appearance of fashionable science and technology, but also provide health data such as exercise, sleep, heart rate and blood oxygen anytime and anywhere, have become a good choice to meet the changes of modern people's health indicators.

Blood oxygen monitoring, for example, is considered inadequate if the oxygen saturation is below 94%. Many clinical diseases will cause insufficient oxygen supply, which directly affects the normal metabolism of cells. It can be said that blood oxygen detection is very important for clinical medicine. However, to trace back to the original method of blood oxygen measurement, it is necessary to collect blood first, then carry out electrochemical analysis by blood gas analyzer, and finally obtain blood oxygen saturation. This method is multifarious and can not realize continuous detection.

With the development of clinical medicine, non-invasive blood oxygen measurement is now widely used. As long as patients wear a fingertip photoelectric sensor, continuous blood oxygen measurement can be realized. Its essence is to use red light with wavelength of 660nm and near infrared light with wavelength of 940nm as intake light source, measure the light conduction intensity through tissue bed, calculate blood oxygen concentration and blood oxygen saturation, and display the results by instrument. Using a similar principle, smartwatches can measure oxygen levels in a person's blood and determine whether they are healthy by measuring arterial oxygen saturation.

And there are many other functions like this, including helping rescue teams locate people who have fallen off cliffs and providing blood oxygen levels for COVID-19 prevention and treatment. Some couples are using smartwatches as a catalyst for love, measuring their heart rates to gauge their heart rate. It can be said that the health monitoring function of smart watches is almost irreplaceable, and it is the long-term trend of intelligent devices in the future.
