The Application Of 9 Major Sensors For Wearable Devices Is Revealed.

At present, the most common technology for collecting body movement data is calculating steps. For the first time, this technology is used on pedometer, and now it also provides consumers with data sources.

In addition to changes in shape -- from

reach

Most pacing devices need to add other functions to detect other indicators of the body.

There are thousands of sensors in the market, and there will be more and more sensors.

Now engineers are using sensors to detect and measure heart rate, sweat, temperature, sleep, reproductive health, calories, GPS coordinates, blood pressure, UV ultraviolet and glucose levels.

Well, these

What are they used for? What products will be used? How do you predict the future?

A simple hardware called PPG can measure blood beats on the skin.

It works by placing a light sensor at a green light. When your blood pulse is under the skin, it changes the brightness of the light sensor, and the change of brightness is the signal of heartbeat.

The hardware is simple, but the data is not accurate enough.

You just need to hand over the sensor, and you can pretend to be a heartbeat.

So smart software developers have added some functions to enable the sensor to get the most accurate data.

This type of hardware also uses smart watches, FitBit, Microsoft Bracelet 2 and so on.

If you see a green light on your wearable device, don't be afraid. It's just a heart rate sensor.

Measuring heart rate is important because it can tell you a lot about overall health.

If your heart beat too fast for your age and body weight, it may mean that some organs of your body are not functioning properly.

In pursuit of healthy life, besides healthy exercise and diet, there is also a life style without stress by healthy heart.

Sweating is the way the body cools and releases toxins. So, for people who are interested in all kinds of human data, sweat is a treasure chest.

A skin electric sensor can detect molecules in your sweat. The sensor sends a small current through the pores. When you sweat a lot, the signal returns faster than it does without sweating.

After analyzing the sweat basically, the sensor can tell you the condition of the body one by one.

For example, if you drank a lot last weekend, sweating this morning in order to catch a bus, you will be surprised to find that your sweat will reveal the secret of your indulgence on weekends.

When the heart rate and sweat sensors are combined, the temperature sensor can reveal a lot of information about a person, first of all, their emotions.

This type of computing data is usually used in emotional computing, especially playing games.

The idea is that computers can know your emotions and react appropriately to them.

If you feel depressed, your skin may become sticky, your heart rate will increase slightly, your body temperature will also rise. After remembering these data points, the computer will let you go out for a walk and breathe fresh air.

Another function of wearable devices co tracking is sleep, which makes the accuracy of different devices different.

Some devices just tell you how long you sleep (but you have to tell it that you are asleep), and other devices know when you are asleep and track your sleep cycle and heart rate.

The most productive and interesting thing is whether you have enough sleep and how long you sleep will always be a topic of debate. But most people agree that 8 hours is the ideal choice.

I like to know if I sleep well, especially if the sensor can tell me when I will go to deep sleep, then I will know that I may lie in bed for 8 hours, but I really sleep for 5 hours.

People no longer need to calculate daily calorie, because wearable technology takes over the task.

Collecting heat calorie data provides important information, especially if you want to know what sports are most effective.

The sensors mentioned above can summon the calorie burning hardware.

Algorithm is the reason why this data is so important.

Some devices will tell you how many calories you take, no detailed descriptions of food and weight, and some tell you how many calories you burn.

Some sports training equipment is equipped with GPS sensors, which is helpful to share travel routes and distance.

In addition to tracking your position, another great thing is to see the altitude you go through.

Not all landscapes are flat. Therefore, the sensor and basic activity tracking can improve the accuracy of exercise.

Measuring blood pressure is no longer a tradition for doctors to use sphygmomanometer and stethoscope.

For those suffering from hypertension or hypotension, it is very convenient to measure blood pressure with a household wireless system.

Although it is not as convenient as wearable devices, it can be carried in bags.

Withings has a very good device that can connect to your smartphone or tablet computer, and you can share any unusual data with your doctor.

As we all know, the sun is also getting stronger and stronger because the O type area is getting smaller and smaller.

This means that every time you go to the Department of Dermatology doctors, they will remind you to put sunscreen cream on the exposed skin every day.

UV detection is an important indicator worthy of attention.

Some devices will measure your time in the sun, tell your age, and your skin sensitivity, at the appropriate time, it's time to go indoors.

Other devices will let you know the intensity of UV light and send a reminder that you need to apply more sunscreen.

Either way, you need a smart phone to help pform data into understandable information.

Insulin measurement is crucial for people with diabetes.

Some devices pass the medical approval, you can measure the glucose content of your body.

Some are chubby watches, while others are small patches. The wearer can decide the style.

However, those who use these devices also need to cooperate.

Because diabetes has to worry about its health every day, it is important to raise vigilance while maintaining a simple lifestyle.

At present, there are many sensors in the development stage, and in the next few years, they will become smaller and smaller.

More and more precise.
