Wearable devices are products controlled by electronic components and software that can be incorporated into clothing or worn separately like accessories. Global companies started developing an increasing number of devices that are small enough to be worn and contain powerful sensor technologies that are able to collect and transmit information about the user.

Wearable devices are most commonly used in the field of healthcare and medicine. They help both to treat some diseases and prevent them. The usage of wearable devices is rapidly growing year by year, along with the improvement of the technologies.


We would like to highlight the main types of wearable devices that are most frequently used.


Smart watches are probably the most popular type of wearable devices. It is possible to view messages, receive calls and control music playback by connecting a smart watch to a smartphone. There is a possibility to pay in stores by connecting a bank card as well. The smart watch can also function as a fitness tracker and collect the user’s data. Smart watches that can be charged from sunlight as well as from human heat have already been invented.


A vivid example of such jewelry is a ring that may be connected to a smartphone and collect data about the user's health. One more example is a pendant-voice recorder that converts voice into the printed text. Well-known jewelry brands started producing smart jewelry in order for it not only to be technologically useful, but also beautiful and fashionable.


Smart glasses are devices that move a computer display in front of a person’s eyes in order to present data with the help of appropriate technology. The display can be broadcast on the glasses’ lens or be a separate component. Smart glasses can also perform voice commands and contain artificial intelligence.


Head-mounted displays (HDMs) are a bit bulkier than other wearable devices. They are worn on the head and provide reflection in front of the user’s eyes. HDMs can function as monitors, provide information superimposed on the reality using augmented reality (AR) or fully immerse the user in virtual reality (VR) settings.


The clothing can collect more accurate and extensive information since it is in contact with most of the body. Smart clothing provides advanced tracking for both healthcare and enhancement of a lifestyle.Smart shirts that can diagnose respiratory diseases as well as smart shoes that monitor running form will be released soon. Smart socks that can detect the development of the foot ulcer, smart yoga trousers that vibrate to improve form during the exercises and smart swimwear that alert the user when the sunscreen should be applied are already available.

Businesses have also started using smart clothing as a way to build brand loyalty. For instance, they install the tracker in clothing in order to determine the frequency of wearing. Gifts and bonuses are provided for the often wearing.


Fitness trackers track the number of steps, heart rate, calories burned and a lot of other metrics. The difference between fitness trackers and smart watches is getting smaller and smaller. Nowadays it is possible to receive calls and have a number of other functions thanks to fitness trackers. However, fitness trackers tend to be cheaper, because they have relatively fewer features and focus on functionality rather than aesthetic appeal.


Implants contact the user’s body from the inside, but not on the skin. For example, pills with sensors that could monitor blood pressure and other health indicators are produced: once the patient swallows the pills, he can wear an external device to easily monitor the data received from inside the body. Smart tattoos that can monitor a user's health are predicted to become popular in the near future.


People without one or more limbs use devices that replace missing body parts. They use a combination of mechanical devices and human muscles to move and act as an additional limb. Nowadays, modern technologies offer not only the creation of realistic limbs, but also intuitive control of prosthetic arms and legs. Smart Prosthetics use the interaction of the human nervous system and the brain in order to improve the accuracy and comfort of movements.


We would also like to separately highlight wearable devices for children. Smart watches have become the most popular. They are specially designed for children, so they are less powerful and more affordable than regular smart watches. In the vast majority they are used by parents in order to track the location of children and to always be in touch with them. Children's smart watches mostly have a fun design, games and interactivity. Some of them include selfie cameras and simple messengers.

Wearable devices are of two types by configuration.

Autonomous systems: this type operates independently by configuration and has no information transmission or communication with other tools and systems.

Integrated systems: these media are integrated with other smart devices, such as watches, smartphones, PCs. These systems transmit vital signs and necessary parameters to other devices. In most cases, artificial intelligence (AI) is added to them for analysis.

Wearable devices such as fitness trackers and smartwatches have already become so common in daily life that they have ceased to be something unusual. Considering the growing demand and desire of users to monitor their own health and vital signs, the usage of wearable devices has more than tripled over the past four years.

According to the research, more than 80% of consumers are ready to wear fitness technologies.

As well, the growth of the market of wearable devices that are used for healthcare affects the decision of insurance companies, medical professionals and companies to take advantage of wearable devices for monitoring the health of patients.

As for insurance companies, they are able to reduce costs per patient as wearable devices promote the behavior that reduces hospital visits and readmissions due to poor control over personal health. On the same grounds, large companies encourage their employees to use wearable devices.


75% of users agree that wearable devices help them to take care of their own health.
