20 Examples and Applications of IoT in Healthcare

Research is going on in every sector of science. Researchers are implementing those applications in different fields to understand the depth of each innovative idea. Technology is becoming more advanced with time. IoT is an upcoming technology with various applications in different fields. Few applications of IoT in the healthcare system may give you a pre-notion over the forthcoming revolution.

Applications of IoT in Healthcare

Lots of existing problems can be solved with the collaboration of IoT. Different IoT solutions can improve the efficiency level of treatment and monitoring of patients. Below we are representing a few ideas for IoT applications in the Healthcare sector.

1. Remote Patient Monitoring


30 percent of medical patients are re-admit into the hospital after surgery. The question is, why? The straight answer is the lack of monitoring patients. Tackling an emergency is still a challenge. Remote patient monitoring can be possible with the collaboration of IoT. Wearable devices with embedded sensors can monitor patient conditions the whole day long and can notify the doctor.

Insights of this application

  • Helps underprivileged rural people with the extended reach of the doctor so that proper guidance can reduce the death rate in rural areas.
  • Reduce travel and hospitalization costs overall.
  • Timely access to data by medical personnel increases the potential of this application.
  • Increasing demand for this type of IoT application in healthcare at any time, anywhere access is possible.
  • Sends a notification to doctors if the patient does not take medicine regularly.

2. Hospital Operations Management


Many people work around the hospital, and it is a crowded, busy place. Stealing medical equipment is a crime that can cost a life. Sometimes doctors are so busy that they don’t have the opportunity to observe multiple patients simultaneously. The Internet of Things in healthcare applications accumulates all the problems and brings the solution.

Insights of this application

  • It can reduce the regular cost of medical equipment by monitoring the current condition of each one.
  • Hospital authorities will know when they have to replace out-of-date equipment and when IoT sensors will send notifications.
  • Monitoring of how much quick response hospital staff can give to the patient.
  • Doctors will be able to know the current location of the required equipment, which can be time effective.
  • IoT applications can now also detect the cleanliness of hospital staff. This IoT in healthcare applications will help to maintain a healthy hospital environment.

3. IoT in Healthcare: Glucose Monitoring


Diabetes is a chronic disease. It occurs for abnormal functionality of the pancreas gland. The main task of the pancreas gland is to produce insulin hormone. Insulin controls the glucose level in our blood. When the pancreas produces less or no insulin, blood sugar can be up and down.

This can lead to vital internal organ damage. So IoT applications with wearable or embedded body sensors that continuously monitor and send data on sugar levels in the blood can minimize the risk of death by diabetes.

Insights of this application

  • Transmitters or sensors send data to the computer or smartphone screen, which can be analyzed by a physician.
  • As it is possible to detect sugar levels, early patients would be able to take the necessary steps early.
  • HbA1c is a protein related to diabetes. If it increases, the risk of the complexity of diabetes can rise. Monitoring the whole day and night by sensor helps to improve the HbA1c level.
  • One of the disadvantages of this type of application is it may not give you 100% accurate results.
  • The treatment of diabetes is still old-fashioned. If IoT in healthcare applications is implemented, it will be a lot easier to save more lives.

4. Connected Inhaler


Asthma is a disease that is not curable, but it is controllable by using an inhaler. Symptoms of an asthma attack can be realized by a patient half an hour to eight hours before. The Internet of Things in healthcare applications can provide smart solutions here. A sensor-connected inhaler can alert the patient to a triggering factor (air pollen, temperature) to prevent an asthma attack.

Insights of this application

  • The use of a mobile app by this application will make it possible to fight respiratory illness for a long time.
  • Accurate monitoring of the current status can prevent future attacks.
  • Doctors will be able to track the status of the illness and notify the patient if the use of an inhaler is necessary.
  • Calculates data found from the sensor and suggests patients take necessary steps.
  • Prevent extra hospital charges by early detection.

5. IoT in Healthcare: Interoperability


Different healthcare organizations started collecting massive amounts of data from IoT devices. Collecting those data, IBM Watson and Teva began a new IoT project that will be responsible for creating new methods of treatment and prediction of chronic disease.
