In addition, it allows to quickly respond to patients’ needs and reduce the downtime, which translates in significant cost savings for medical providers and patients alike. 

IoT for Smart Healthcare

HIoT (healthcare Internet of Things) applications contribute to digital revolution in healthcare sector and improvement of medical service quality. 

IoT technology implies sensing activation and aggregating data from human body as a collecting target. Breaking down the technology implication, IoT-based operation in healthcare looks as follows: 

  • Interconnected devices collect health-related information from a patient that transfers as the input of data. These devices can include monitors, camera systems, sensors, actuators, and detectors.
  • The data received from the sensors in analog form needs to be aggregated and converted into digital streams.
  • After the IoT data has been digitized and aggregated, further processing may be required before it reaches the data center, this is where Edge Analytics comes in. After this, it is transferred to the cloud or data center.
  • Thus, physicians, medical professionals, or virtual assistants get the opportunity to take result-oriented and informed decisions with data received through IoT-based devices.

Another example of smart IoT solution in healthcare pertains to merging IoT and digital twins technology

When creating a digital replica, digital twins capture and aggregate data collected by sensors on medical products: consequently, it is sent back to a platform via an Internet of Things (IoT) network. It allows doctors and healthcare providers to track patient data with precision, monitor treatment progress immersively and construct a digital model of the patient, which potentially elevates customer experience to a completely new level.

Medical Professionals 

Getting data from monitoring equipment via IoT, doctors have wider opportunities in addressing health management and treatment issues. IoT-based devices assist physicians in enhancing positive medical outcomes.

Healthcare Facilities 

Using IoT-based devices in hospital set up greatly facilitates healthcare management operations. For example, with assistance of IoT, it is easy to track location and utilization of any kind of medical equipment in real time.

The numerous IoT examples also confirm the considerable reductions on capital expenditures once IoT healthcare solutions are brought into picture. Below, we explore some of the IoT applications in healthcare in greater detail due to their time proven status of game-changers in healthcare provision.   

The market offers a wide range of products, from complex surgical and endoscopic connected products to everyday IoT wearables of all different types.


People with hearing impairments discovered advantages of IoT healthcare wearables for better health management and amplified listening experience with additional augmented options built in various hearables. 

Apple AirPods’ presented new Live Listen feature that hugely widened opportunities of interactions with the environment for people with hearing loss. This and similar hearables assist millions of patients just by connecting to smartphones.  


With moodables, customers tap in better health management by getting low-intensity current to stimulate brain. 

Applying this head-mounted device also elevates mood almost instantly and augments antidepressants effect. One of the prominent vendors offering IoT-based solutions in this field is US-located Halo Neuroscience

Healthcare Charts 

By implementing healthcare charting doctors can save hours of working time on documenting the patient history, inputting test results, or history of medications intake. One of the companies that provide seamless experience in healthcare charting is Augmedix.

Its experts apply Google Glass technology to activate voice commands and input data instantly, by using a HIPAA-certified encrypted network.

Cancer Treatment

Curing cancer has always been a focal point for healthcare practitioners and technology innovators. At present, precision medicine and implementation of advanced healthcare equipment change the medical landscape. 

IoT-based devices that use machine learning and predictive analytics at the stage of prevention show wide capabilities in analysis of collected data and classifying abnormal patterns indicating cancer. 

For example, with iTBra that women can wear once a month for 2-12 hours, breast cancer diagnosis gets more efficient. The device is worn as regular lingerie, and the results of the performed test will be transmitted to a smartphone: this solution recommended itself as the effective measure within breast cancer prevention.

Hygiene Monitors 

The sophisticated environment monitoring systems implemented in hospitals can help enhance patients’ safety when they are admitted for medical treatment.

In case of applying hygiene monitors, the wireless sensors deployed on the mesh network periodically transfer data to an internal gateway device and display dashboard information on preliminary set hygiene and safety parameters inside medical facilities including the operation theatre in the hospitals. 

The data visualisation tools send early insights for addressing compliance and maintenance issues without fail.

Sleep Monitors 

Sleep monitoring IoT apps provide a real-time monitoring of any sleep-associated disorders, for example, obtrusive sleep apnea. Sleep monitors  proved to be the effective healthcare solution for detection of disturbing symptoms related to human sleep. 

For instance, Beddit sleep monitor enables consumers to measure and manage their sleep by retrieving insightful data through automatic and accurate sleep time tracking: patients and medical professionals have access to full information pertaining to patient’s sleep including quantity of sleeping hours, stress level, heart rate and environment conditions during sleep.
