To say that modern medicine is striving would be a moderate expression. The progress accelerates daily ‘without any remorse’, transforming all known medical practices. Global healthcare evolves based on the latest achievements of the planet’s greatest minds and amazing prospects of autonomous, self-learning tech solutions.

Along with such rapid development, however, comes a strict necessity to keep up with the pace. The good thing is that all medical fields are either looking to or already go hand in hand with advanced technologies – from diagnostics to therapeutics, from pediatrics to complex surgery.

internet of things in healthcare

Technologies are numerous – artificial intelligence, machine learning – you name it. But what particular tech concept or combination of concepts can provide sufficient monitoring and managing powers such an evergrowing global niche requires? The answer may be found in the Internet of Things or IoT. Despite the concept’s relatively young age, it’s already become closely entangled with healthcare. So much so that it’s commonly coined the Internet of Medical Things.

It’s easily explained by the numerous benefits of IoT in healthcare and how it helps to improve medical services. The adoption of IoT devices for healthcare allows the industry to provide better patient care and experience, improve management, reduce errors, improve treatment outcomes, etc.

The extensive centralization and interconnection capacities the IoT tech provides are difficult to overestimate. It brings health monitoring, remote treatment, and hospital physical and digital infrastructure organization to a whole new level.

IoT is a rapidly growing technology that connects everyday objects to the internet, allowing them to communicate and share data. 

This technology has the potential to revolutionize many industries, including healthcare. By connecting medical devices, wearables, and other healthcare-related technology to the internet, IoT enables new forms of remote monitoring, telemedicine, and medical device connectivity. It’s important to explore the place of IoT in healthcare and the benefits it can provide to patients, healthcare providers, and the healthcare system as a whole.

In healthcare, IoT can potentially improve patient outcomes, reduce costs, and increase efficiency. Remote patient monitoring, for example, allows healthcare providers to track vital signs and other health data in real time, which can help identify potential problems early on and intervene before they become serious. Telemedicine, which uses technology to connect patients with healthcare providers remotely, can increase access to healthcare for those in remote or underserved areas. Additionally, medical device connectivity can improve communication and collaboration between healthcare providers, helping to ensure that patients receive the best possible care.

IoT can also help reduce healthcare costs by increasing efficiency and automation. For example, by using IoT to track inventory and automate ordering processes, hospitals can reduce the amount of waste and improve their bottom line. Additionally, by using IoT to monitor patients remotely, healthcare providers can reduce the need for expensive hospital visits.

Furthermore, IoT can also play a crucial role in the future of healthcare by enabling new forms of precision medicine, drug delivery, and virtual reality-based therapy. With the help of IoT, medical professionals can gain a deeper understanding of patients’ health, disease, and treatment outcomes, which in turn can lead to more individualized, efficient, and effective treatments.

So let’s ponder IoT powers in healthcare in a bit more detail.


The Internet of Things allows the setting up of a centralized network of interconnected devices to generate and exchange data within a single framework. All that data can also be tracked and gathered in real-time, which provides a passive accumulation of analytics materials. In terms of enhancement for medical facilities, this means that a regular hospital can be turned into a smart hospital.

It is an advanced facility where everything is tracked and managed simultaneously while all the data is collected in a centralized database. Such tech features open a myriad of benefits of IoT in healthcare to improve modern hospitals’ convenience, efficiency, and even budget-saving options.

One of the main types of IoT devices in healthcare is wearable devices. These include smartwatches, fitness trackers, and smart clothing. These devices can track a patient’s vital signs and activity levels and send that data to healthcare providers for analysis. Smartwatches, for example, can measure heart rate, sleep patterns, and steps taken, while smart clothing can track posture and breathing.

Another category of IoT devices in healthcare is medical devices. These include remote patient monitoring devices, such as smart pills and smart inhalers, which can track a patient’s medication adherence and send that information to healthcare providers. Smart pills, for example, have a sensor that sends a signal to a wearable device or smartphone when the pill has been ingested, and smart inhalers can track how often and when a patient uses their inhaler.

Home healthcare devices, such as smart medication dispensers, telehealth devices, and smart home assistants, are also becoming increasingly popular in the healthcare industry. Smart medication dispensers can remind patients when to take their medication and even dispense the correct dosage. Telehealth devices, such as video conferencing software, allow patients to have virtual consultations with their healthcare providers. Smart home assistants, such as Amazon’s Alexa or Google Home, can provide patients with information about their health and medication and answer general health-related questions.

There are many advantages to using IoT devices in healthcare. They can improve patient outcomes by providing healthcare providers with more accurate and up-to-date information about a patient’s health. They can also increase efficiency in healthcare delivery, as well as reduce costs. Additionally, IoT devices can increase patient engagement and empowerment, as patients are able to take a more active role in their own healthcare.

The advantages of IoT devices for healthcare continue beyond there. Technology has a very diverse field of application in medicine. Let’s take a look at some major implementations.


Remote patient monitoring

In 2018, NHS England – an ‘executive non-departmental public body of the Department of Health and Social Care’ announced that it’s willing to support a remote diabetes treatment solution. The statement was made on World Diabetes Day 2018. The solution is a Continuous Glucose Monitor (CGM). A device the size of a penny monitors blood glucose levels non-stop after it’s inserted in a patient’s arm.

The monitoring data can be easily accessed via your Android or iOS device. Mass-market instances of such products are Freestyle Libre and Eversense. Such smart health monitoring devices bring huge value to the research and treatment of diabetics.

Also, going deeper into the remote subject, the IoT network can connect and track practically any sensor inserted into a human body for medical purposes. This will help prevent cardiac arrests (MoMe Cardia from InfoBionic) and all sorts of seizures to provide medical help for critical patients just in time.

Cardiac monitorInfoBionic’s wearable cardinal tracker streams ECG and motion data to the doctor in real time.

Tracked ingestible sensors

The World Health Organization conducted a study in 2003 to find out that about 50% of prescribed medicines aren’t taken correctly or completely ignored. A prominent example of resolving this issue is the ingestible sensors solution developed by Proteus. These tiny sensors take the place of a prescription and send a signal to a receiving device upon dissolution in the stomach. An amazing advanced creation, Proteus’ ‘smart pills’ will surely help reduce the rates of incorrect, senseless consumption of highly important medical prescriptions. Now, this is what one can call truly advanced drug management.

Practically all such situations can be turned around with the integration of IoT solutions. Huge, cumbersome paper registers can be replaced with an automated, centralized database, which can be additionally enhanced in terms of reliability with blockchain and smart contracts; a single management system can receive submissions, help optimally control queues, and track staff members via their smartphones; all the equipment can also be remotely monitored and managed (e.g., shut down in unprecedented cases).

Such innovations can help greatly reduce in-house costs for hospitals, preserve forests, and make both patients and medical staff’s lives easier. The overall productivity will also increase due to the automated smart solutions’ capability to immediately recognize health issues that would otherwise take months of live doctor diagnostics. The benefits of IoT in healthcare are highly valued by medical practitioners and patients.

Enhanced chronic disease treatment

With IoT-powered wearables, sensors, data analytics, and mobile opportunities, battling chronic diseases becomes more efficient and accessible. The thing is, recurring health issues must be monitored and analyzed over long periods. That way, trends in the disease fluctuations can be defined and juxtaposed to be most efficiently treated.

All that tech allows doing just that, with many additional capabilities provided by the integration of blockchain and AI on top of that. It allows developers to bring more benefits of IoT in healthcare. This is very important when it comes to health issues as difficult to understand and underexplored as the chronic ones. 


As much as the Internet of Medical Things seems to be revolutionary and highly efficient, there are still some major challenges of IoT in healthcare this tech concept must overcome down the road. With large, game-changing integrations such as this one, there comes along a myriad of technical difficulties and adaptation issues. The main include:

  • Underdeveloped initiatives. Many IoMT initiatives directed at battling chronic diseases or other issues still need time to grow and develop. This technological niche as a whole must grow a lot to start providing regular enhancement results.
  • Possible lack of available memory. IoT sensors and devices can generate colossal amounts of data, which is important and needs to be analyzed. This poses a question of huge data repositories that must hold all those data volumes for indefinite terms. Cloud solutions turn into one of the decisions here. 
  • Difficulties with regular updates. With so many hardware solutions comes as much software for powering and managing it all. This software must be timely updated in order to run smoothly and stay at its latest version. And here’s where constant updates require lots of effort and might spawn many technical issues.
  • Personal sensitive data security. An IoT-powered medicine has to follow all the latest security compliance regulations and adopt the best approaches to secure medical data. Encrypting data allows business associates and healthcare providers to make it difficult for attackers to decipher patient data even if they gain access to it.
  • Global healthcare regulations. The IoMT still has to be approved by global healthcare regulatory bodies worldwide. This will take time and may keep many innovations at bay just because of some formalities.


Considering the above-mentioned challenges, there are, indeed, downsides and benefits when it comes to medical IoT.

Advantages of IoT in healthcare

The ‘all-consuming’ connection of health devices and data centralization brings many significant benefits of IoT in healthcare to the table, such as:
