Fitness bracelet with pulse and pressure measurement function

Fitness bracelets with a different set of functions are beginning to gain more and more popularity. This is not surprising, because such devices are very convenient and useful. The main functions are the measurement of pulse and pressure. Today, the word "fitness" has acquired a broader meaning than it was originally intended. Everyone needs to monitor their health 24 hours a day. It was for this that a device was invented that can control the state of the body.

"Smart" device exists in the form of wristbands and bracelets that are worn on the wrist. They are very comfortable to wear, which is noted by many users. In fulfilling their medical purpose, these devices act as normalizing vital parameters. These include pulse and pressure.

When doing cardio in the gym (or giving your body some kind of load), wearing such a bracelet would be a very right decision. Such products are also relevant for the elderly, because information about the heart rhythm is also important for them.

There are generalized parameters, but the body of each person is individual. You should have a clear idea of ​​​​your result of the measured readings.

These devices are equipped with various sensors that can read information from your body and the environment.

Almost all of them have a heart rate monitor that measures heart rate. This feature is highly appreciated by users. By fixing this parameter, you can easily display a cardiogram describing the work and condition of your heart on the monitor.

Due to certain circumstances, the heartbeat can become faster and slower. This should be taken into account when analyzing the cardiogram.

These factors include time of day (during the day, the value is greater than at night), ambient temperature (as it increases, the heart rate also increases), food intake (also contributes to increased frequency). The heart rate for women is slightly higher than for men. Damage to the body and diseases in this period are also important. Height also affects the pulse. Taller people have a slightly lower heart rate than people of medium and small stature.

If the condition worsens, accompanied by a change in the heartbeat, it is worth sounding the alarm. After all, a decrease in it may be evidence of hidden lesions of the heart, inflammation of the tissues of the heart muscle, increased intracranial pressure, peptic ulcer disease, myocardial infarction (or serve as a sign of intoxication in the body).

An important function of these bracelets is a sensor that shows the pressure of a person. The value of pressure refers to the force with which the blood flow affects the surface of the vessels. This indicator depends on the volume of blood passed per minute. There is a set of values ​​​​of blood pressure (blood pressure) norms, according to which the state of the body is determined.With it, you can track the functioning of the organs as a whole and each system separately.

Blood pressure is an individual indicator, its value depends on various factors. We can single out the main ones:

• heart rate and strength;
• atherosclerosis;
• constriction and expansion of blood vessels;
• the work of the endocrine system;
• feature of blood.

The indicator depends on the person's age, weight, time of measurement, lifestyle and other factors:

• the norm of blood pressure is considered to be 120/80;
• reduced ranges from 110/70 to 100/60;
• slightly elevated can be called from 139/89 to 130/85;
• 140/90 or more is considered high.

Together, these factors are determined by the tonometer built into most bracelet models.

After the first pedometer released in the 60s, a theory appeared that for the body to work properly, 10,000 steps must be taken per day. At present, given the image and diet of people, it is believed that this amount is not enough. It needs to be doubled. Nevertheless, such a distance will be useful for the healing effect. After all, it's much better than nothing.

Sometimes we have no idea about the number of steps taken. Thanks to the pedometer built into the smart device, you can easily track and control the value for the past day.

Gradually increasing their number, you can help improve the functioning of the body as a whole. After all, movement is life.Everything begins to change precisely at the moment when there is a conscious violation of the measured life of a person. Find the strength to improve your health, and the body will be grateful to you throughout your life.

Helping you start a new day alarmpresent in the device.

Every modern person tries to control his sleep phase and the time spent in it. The principle of awakening the body is that the worn device produces pulsating actions for the time that you have set in advance. Waking up, you can see all the phases. This data records the time when you fell asleep, woke up, as well as the period of deep and intense sleep.

There is also a useful function that allows you to program an alarm for the necessary days of the week.

Typically, the devices are watertight, capable of maintaining normal operating conditions when submerged to a certain depth. Thanks to this, there is no need to remove them while taking a shower or exercising in the pool.

All fitness bracelets have a similar principle of operation. The main underlying element is a device called an accelerometer. This is a device that determines the difference between the values ​​of the change in motion in space relative to the acceleration of gravity. Usually it is made in the form of sensitive devices, combined into one, which is further enclosed in a suspension. The result is a part that can capture any change.

A typical accelerometer has two boards with electric charges, a counterweight is located between them. In the process of interaction of the counterweight with the boards, a spatial picture of the movement of the holder in the three-coordinate system begins to be created.

For some devices, other functions are included:

• fixing the geographical position - thanks to GPS (satellite navigation system);

• measurement of body temperature, environment, sweating (if there is a temperature and humidity sensor);
• burning calories;
• recognition of activity types;
• motivating task system.

Basically, there is no software for these parameters, there is only their fixation.

If you install a program for devices (such as tablets and smartphones), then when the bracelet and the device interact, it becomes possible to analyze, organize and systematize the activity of the owner. To complete the program setup, you will need to enter the basic parameters of the owner. These are age, height and weight. They are necessary for more accurate calculations of the obtained values.

Your read data enters the program via Bluetooth or Wi-Fi. Then the program is processed, and as a result you get the result in the form of diagrams or graphs.

After reviewing the results, you can adjust physical activity and lifestyle, making them optimal. By doing these steps, you will get excellent health and do not overwork in the presence of excessive stress.

The availability of each feature depends on the model you choose. Consider exactly what you need. Then you will get exactly the device from which you will get the maximum benefit.

They are about half the price, therefore, more affordable. The precise programmed basis in the bracelets results in more information about its owner.Longer run time is also an advantage.

To decide on the choice of a particular model, it is important to clearly understand the criteria you need. After that, it will be possible to compare the devices with each other, choosing the best option.

The pricing policy is quite diverse. There are a large number of devices that can be called good in the price segment up to five thousand rubles. This option usually combines a set of basic functions. It will be suitable for you if you do not want to overpay.

The next selection criterion is the platform. Often, these bracelets interact with tablets and phones, capturing and analyzing all the data. It is worth considering this point before buying.

Almost always, the basic functionality remains unchanged and is identical for all devices. The number of steps taken, distance, calories burned - this is the sufficient minimum for many. In more expensive models, you can find the presence of such functions as the number of heartbeats, weight and diet control, GPS tracking, the ability to answer incoming calls.

Free time is also extremely important. Usually, the work of a fitness bracelet without recharging reaches one month.

For those who lead an active lifestyle, doing various sports, the right decision would be to choose waterproof bracelets. They are very comfortable while swimming.

Raw materials for the manufacture of devices are the most diverse.

Straps for them can be:

• nylon with a sticky fastener;
• solid rubber, making the bracelet more durable;

• rubber with metal fasteners that allow you to adjust the size;
• silicone without a fastener, with greater elasticity (unlike rubber);

• silicone with a holster button;
• leather clasp.

The outer casing is mainly made of plastic and rubber. The elements inside can be made of various alloys, copper or graphene. The latter material is able to generate less heat, allowing the creation of conductive connections with a thickness of less than 22 nanometers. The speed of movement of charge particles in graphene and mobility have a higher indicator than in the previous ones.

At the same time, copper elements remain common to this day (due to their reliability).

For more expensive models, there is a special technology - twelve stages of metal coating processing.

The main module has a metal coating one millimeter thick. This action takes place in twelve stages. The element is made using the mold method, then polished and sandblasted. When forming the effect of a mirror for the edges, face milling is performed. Thanks to the process of laser microperforation, holes are drilled (in the amount of 91). Each of them is 0.02 mm in diameter. Together, they create three indicators - with a diameter of 1 mm. Holes are filled with specially designed UV adhesive (to prevent dust from entering the device).
