Fitness bracelet with pulse and pressure measurement

Fitness bracelets with a different set of functions are becoming more and more popular. This is not surprising, because such devices are very convenient and useful. The main functions are heart rate and pressure measurement. To date, the word "fitness" has acquired a wider meaning than was originally intended. Every person needs to monitor their health 24 hours a day. For this purpose, a device was invented capable of controlling the state of the organism.

A “smart” device exists in the form of wristbands and bracelets, which are worn on the wrist. Wearing them is very convenient, which is noted by many users. Performing 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 any load) to wear this bracelet would be a very good decision. Such products are also relevant for older people, 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 about your result of measured readings.

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

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

Due to certain circumstances, the heartbeat may increase and slow down. This should be taken into account when conducting a cardiogram analysis.

These factors include the time of day (during the day the value is greater than at night), the ambient temperature (as it rises, the heart rate increases), food intake (also contributes to more frequent). The heart rate for women is slightly higher than for men. Also important are the lesions of the body and the disease in this period. Growth also affects the pulse. People with higher growth have a heart rate slightly lower than people of medium and small stature.

With the deterioration of the condition, accompanied by a change in 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, ulcerative pathology, myocardial infarction (or be a sign of intoxication in the body).

An important function of these bracelets is a sensor showing the pressure of a person. The value of pressure implies the force with which the blood flow affects the surface of the vessels. This indicator depends on the amount of blood passed per minute. There is a set of values ​​of the norms of blood pressure (blood pressure), which is determined by the state of the body. 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. You can select the main ones:

• heart rate and their strength;
• atherosclerosis;
• vasoconstriction and dilation;
• the work of the endocrine system;
• blood feature.

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

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

Taken together, these factors are determined by the tonometer, built into most of the bracelet models.

After the first pedometer was launched in the 60s, a theory emerged that for the body to work properly, it is necessary to do 10,000 steps per day. Currently, given the image and diet of people, it is felt that this amount is not enough. It needs to be doubled. Nevertheless, such a distance would also be useful for a healing action. After all, it is much better than nothing.

Sometimes we have no idea about the number of steps. Thanks to the pedometer built into the smart device, you can easily monitor and control the value over the past 24 hours.

Gradually increasing their number, one can contribute to the improvement of the work of the organism as a whole. After all, movement is life. Everything begins to change at the very moment when there is a conscious violation of the measured vital activity of a person. Find the strength to improve health, and the body will be grateful to you throughout life.

Start a new day will help you alarm clockavailable in the device.

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

There is also a useful feature that allows you to program the alarm for the required days of the week.

Typically, devices are waterproof, capable of withstanding a normal working condition when immersed to a certain depth. Due to this, there is no need to take them off while taking a shower or swimming in the pool.

All fitness bracelets have a similar working principle. The main element underlying the device is the 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 further consists in a suspension. The result is a part that can catch any changes.

A typical accelerometer has two boards with electric charges, between which there is a counterweight. 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, there are other functions:

• fixation of geographic location - thanks to GPS (satellite navigation system);

• measurement of body temperature, environment, perspiration (with a temperature and humidity sensor);
• burning calories;
• recognition of activity types;
• motivating system of tasks.

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 device interact, it becomes possible to analyze, organize and systematize the activity of the owner. To complete the setup program will need to enter the basic parameters of the owner. This is 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 there is a processing program, and in the end you get the result in the form of charts or graphs.

After reviewing the results, you can correct physical activity and lifestyle, making them optimal.Doing these steps will give you a great feeling and will not overwork if you have an excessive load.

The presence of each function depends on the model you choose. Consider specifically those that you need. Then you will get exactly the device from which you will receive maximum benefit.

They are about two times cheaper, therefore more accessible. The exact programmed base in the bracelets as a result gives more information about its owner. Longer hours are also an advantage.

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

Pricing policy is quite diverse. There are a large number of devices that can be called good in the price segment of 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, recording and analyzing all the data. It is worth considering this moment before buying.

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

Independent work time is also crucial. Usually, the work of a fitness bracelet without recharging reaches one month.

For those who lead an active lifestyle, engaging in 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 sticky clasp;
• solid rubber, making the bracelet more durable;

• rubber with metal clasps that allow you to adjust the size;
• silicone without fasteners, with greater elasticity (as opposed to rubber);

• silicone with cobranded button;
• leather on the clasp.

The outer casing is mainly made of plastic and rubber. Elements inside can be made of various alloys, copper or graphene. The latter material is able to emit less heat, allowing you to create conductive compounds with a thickness of less than 22 nanometers. The speed of movement of charge particles in graphene and mobility are more important than in previous ones.

In this case, copper elements remain common to this day (due to its reliability).

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

The main module is coated with one millimeter thick metal. This action takes place in twelve stages. The element is manufactured using the mold method, then polishing and sand blasting are performed. When shaping the effect of a mirror, edge milling is performed for the edges. Due to the process of laser microperforation, holes (91) are drilled. Each of them with a diameter of 0.02 mm. Together, they create three indicators - with a diameter of 1 mm. Holes are filled with UV glue specially designed for them (to prevent dust from entering the device).
