Examples of Healthcare IoT

IoT has some very interesting applications in the healthcare sector. The advances in the applications of IoT in the health area are occurring every day. Here are some of the examples that are bound to provide ultramodern medical solutions to some of the age-old medical problems and conditions.

1. Real-time health systems (RTHS)

  • DocBox: It is a vital sign monitoring system that can analyze a high volume real-time data inputs from critically ill patients in ICU (Intensive Care Units) and reduce the time nurses spend on transcribing data so they can focus on other important tasks such as care delivery.   
  • Activity Tracker amid Cancer Treatment: A cancer center has devised a tracker to collect lifestyle information of myeloma patients. The patient is required to wear the tracker for a week before or more for the treatment of cancer so the doctors can be absolutely certain about the information they need.
  • Sensors that can be Ingested: Proteus Digital Health has created sensors in the form of pills that can be swallowed and are being dubbed as digital medicine. The company has produced a pill that treats psychotic ailments and hypertension. Both the kind of diseases in which people lose their commitment to take the pill on a recommended basis. A study by the World Health Organization (WHO) has shown that 50% of the prescribed medication is not taken as directed by physicians. Proteus is determined to reduce this figure.

The pill has sensors monitors adherence of the patient. The pill gets dissolved in the stomach of the patient and produces small signals that can be picked by a small wearable sensor that can relay the data to a smart device.


2. IoT in Healthcare/Medical Projects

The IoT has a very significant contribution to the Healthcare technology industry. There have been several projects that engineers are working on, a hand full of them is mentioned below.

  • Consumer Home Monitoring:

    Pioneered by a startup project by a group of companies. The project includes monitoring systems like “Qardio” and “AlivCor” allowing consumers to do their ECG (Electrocardiogram) testing from the comfort of their homes without visiting the cardiologist.


There are great chances that the healthcare devices based on IoT will penetrate much deeper in our lives and the future of these technologies seems very bright and exciting.

  • Blockchain-Based Innovations:

    Blockchain had its cradle in Fintech. A cryptocurrency called Bitcoin became the cradle of Blackchin. A concept that was pioneered by Satoshi Nakamoto, a cryptographer, and a mysterious figure has created the concept of a distributed database that can communicate with computer peers sharing and verifying information on a consensus basis. As different computers communicate they confirm the validity of the information they contain. The blockchain is extremely huge and has found numerous innovative applications in and around the financial industry including medical healthcare.

Until now, there are no known methods to hack the blockchain data and this leads to secure transactions, safe data storage, secure data exchange, and virtually immutable medical records. Moreover, the transparent data flow is the advantages that make it unique to protect the privacy and security of the patient’s data. The medical organization is taking the initiative to incorporate blockchain into their systems to secure scores of medical records over the network.
