IoT Applications in Healthcare

With the Internet of Things, devices can communicate and exchange data within a centralized network. It is possible to gather all of that data in real-time, which provides a passive collection of analytical materials. As an enhancement for medical facilities, this means a regular hospital can become a smart hospital.


The facility is an advanced one where all data is centralized and tracked simultaneously. With these tech features, modern hospitals have many options to improve their efficiency, convenience, and even cost savings.

There are many more benefits of IoT applications in healthcare. This technology has a wide range of applications in medicine. Let’s take a look at a few examples.


Remote patient monitoring

As of 2018, NHS England has announced its willingness to support remote diabetes treatment as a non-departmental public body of the Department of Health and Social Care. The announcement took place on World Diabetes Day 2018. CGMs (Continuous Glucose Monitors) are a possible solution. Once inserted into the arm of a patient, the device monitors blood glucose levels continuously.

You can easily access monitoring data using an Android or iOS device. Some of these products are available on the mass market, such as Freestyle Libre and Eversense. Diabetes research and treatment are greatly enhanced by smart health monitoring devices.

Throughout its 90-day life, the Eversense continuous glucose monitoring sensor can be implanted in the patient’s arm.

Remote patient monitoring with IoT

The use of remote capabilities (also known as telehealth) may make visits to the local hospital virtually unnecessary in other situations. This is especially helpful for people with mobility problems.

To further delve into the subject, the Internet of Things is capable of connecting and tracking virtually any medical sensor that is implanted into a human body. Medical help will be provided just in time for critical patients, as well as preventing cardiac arrests (MoMe Kardia from InfoBionic).

Tracked ingestible sensors

According to a 2003 study conducted by the World Health Organization, about 50% of prescribed medications aren’t taken correctly or are ignored. Proteus’ ingestible sensors solution is one example of how to address this issue. Upon dissolution in the stomach, these sensors replace prescriptions and send a signal to a receiving device.

Proteus’ ‘smart pills’ are amazing technological advances that will surely contribute to reducing the rate of incorrect, unnecessary consumption of important medical prescriptions. These are truly advanced methods of medication administration.

Its size is the same as a regular pill, even though Porteus Smart Pills are a cutting-edge piece of medical technology. There are also smart pills that contain tiny cameras, allowing users to view their body’s interior environment. The Medtronic PillCam is an example.

Mobile health

Mobile health, which includes watching and managing one’s health via mobile, can be a real lifesaver for modern patients since virtually everyone owns a smartphone. The mobile health industry makes a significant contribution to critical situations as well as regular treatment instances. Health tracking devices can be managed through mobile apps, as we have already discussed in the section titled ‘Remote patient monitoring.’

There are only a few startups that are using their apps to gain market share. Apps like these can serve as a full-blown healthcare hub, providing access to valuable medical information, analyzing organism patterns, managing other body-inserted IoT sensors, and contacting your doctor with a single tap.

The solution is especially valuable for countries with underdeveloped healthcare systems where people cannot afford to visit hospitals regularly yet possess smartphones. As a result, governments are able to monitor the health of the population and compile massive statistics.

The App Store already has a number of apps with various functions and purposes:

  • Apps for managing medications;
  • There are Apps for fitness
  • Apps for tracking your body, activity, and sleep
  • Monitoring apps for pregnant women
  • Apps for recording individual health information

The list could go on and on. On a mobile application market compatible with your operating system, you can check it all out yourself.

Smart hospitals

Smart hospitals

A vast majority of countries on the planet (even the developed ones) are unhappy with their flawed, difficult-to-manage hospital infrastructures. It is the enormous amount of paperwork, the long and frustrating lines, and the overwhelming workload doctors and nurses face that is at the root of the problem.

Smart healthcare system with the help of IoT development

The integration of IoT solutions can turn around practically all such situations. With the help of blockchain and smart contracts, cumbersome, massive paper registers can be replaced by an automated, centralized database; an all-inclusive management system can receive submissions, control queues, and track staff members in real-time via smartphones; all equipment can also be monitored and managed remotely (e.g., shutting down in an emergency).

Investing in such innovations can significantly reduce hospital costs, protect forests, and make patient and medical staff lives easier. A smart automated solution will also result in increased productivity as it can identify health problems immediately, which would otherwise require months of live doctor diagnosis.

Improved treatment for chronic diseases

IoT based Smart hospitals

Through the use of wearables, sensors, data analytics, and mobile technology, chronic diseases can be treated more efficiently and effectively. 

The issue is that recurring health issues must be tracked over time and analyzed. Identifying trends in disease fluctuations and juxtaposing them to determine the most effective treatment method can be done that way.

All of that tech allows doing just that, with many additional capabilities provided by the integration of blockchain and artificial intelligence. As difficult and underexplored as chronic health issues are, this is crucial. 

Challenges of IoT in Healthcare

Despite the fact that the Internet of Medical Things appears to be a highly efficient and revolutionary tech concept, there are some major challenges that must be overcome until IoT is fully implemented in healthcare. A large, game-changing integration like this entails a variety of technical difficulties and adaptation challenges. The main include:

  • Initiatives that need to be developed. There is still a long way to go for many IoMT initiatives addressing chronic diseases or any other issues. In order to achieve regular enhancement results, this technological niche as a whole must grow significantly.
  • There may not be enough memory available. There is a huge amount of data generated by IoT sensors and devices, which must be analyzed because it is important. All these volumes of information must be stored in indefinite data repositories.
  • There is a problem with regular updates. Many hardware solutions come with as many software tools to manage and power them. To work smoothly and stay at its latest version, the software must be updated on a regular basis. The constant updating will take a lot of time and effort and could result in many technical problems.
  • Data security for sensitive personal information. A hardware-based Internet-enabled medicine is one that uses the Internet for its functionality. The Internet is susceptible to hacking and breaching. Potentially sensitive private data can be undermined due to this.
  • Regulations in global healthcare. Regulatory bodies worldwide must still approve the IoMT. Due to formalities, many innovations may be delayed for some time.
