The principal promoting innovations for fourth medical revolution.

Technology	Feature
Telemedicine	This technology is useful for ensuring social distancing during the COVID-19 pandemic. It is beneficial for medical care in rural areas to use telecommunication technologies.
Biosensors	Biosensors can be used to distinguish signs of viral infection related to COVID-19. Useful to measure temperature and related changes in the patient’s symptoms. Perform the necessary functions as per the sensor’s design in any crisis.
MIoT	MIoT connects all healthcare tools and devices to the Internet to access real-time information. It gives greater control of chronic conditions.
Robotics	This technology is used in the hospital to scan an infected patient. Scan all patients, healthcare staff, and guests, with minimal risk to the doctors. Provide critical and noncritical services in remote and challenging locations.
Cloud storage platform	The platform uses computers to store data in cloud storage. All information is stored remotely after the care of the infected patient, which helps to achieve improved outcomes in the future.
Data security	Data management guarantees the security of medical data. Improves the administration of various therapy programs. Helpful in preserving and tracking confidential information about the transmission of this outbreak, inventory of services, medications, etc.
AI	AI with adequate preparation has a human-like intellect that helps anticipate, monitor, and interpret signs of COVID-19 or related diseases. It analyzes signs of cold, cough, fever, and other symptoms in patients with COVID-19. Enables support for telemedicine and provides tracking for individuals and clusters. Can be built into other systems and technologies for predictive analysis and disease modeling. Has implementation in the manufacture of drugs/vaccines. Helpful to classify the mortality rate and other anomalies of disease data.
Analytics of big data	The entire medical history of all patients is digitally, and anomalies are further examined. stored Rapidly recognize any signs of the given virus.
Bioactuators	Provides essential functions for the patient’s bed, operating table, and chair. Raise and lower bed according to the patient’s needs during treatment.
Blockchain	Pandemic control system algorithm for COVID-19. Applicable during a crisis for patient track and trace and disease/infection prevention. Involves outlining in the early stages of the disease.
Information technology	Provides a considerable change in information and data processing. Helps with the availability of backbone hardware and software for care.
Imaging technologies	Increased reality (AR)/virtual reality (VR) systems will promote learning and training in remote locations. AR/VR images can be used by a remote specialist in patients with major defects and recommended treatment. Health apps can encourage increased patient satisfaction.
Additive manufacturing	Consists of 3D scanning, 3D printing, and other software design and printing. 3D scanning is helpful to construct the necessary design for a part of the patient. 3D/4D/5D printing consumes less time and money, and satisfies the scarcity of critical COVID-19 pandemic items. The optimized design could be researched, evaluated, and improved.
Nanomedicine	Aid in healing infected patients’ cells with the help of protein repair. Nanoparticles the size of the novel coronavirus can be successfully used in patient care. Has the ability to cure and control infections in this ongoing scenario.
