Interestingly, IoT takes the credit for making Digital Twin technology one of the most cost-effective and functionally-feasible digital wonders of all times.
So, What Exactly is the Digital Twin technology?
Digital Twins can be defined as the virtual replicas of all physical entities or assets, both living as well as non-living. This includes digital systems, IoT products, places, people, jet engines, building a factory floor or next-gen processes. The idea behind creating a digital twin is to digitally represent both the dynamic as well as physical properties of an Artificial Intelligence (AI) or IoT product, so as to record, analyze and interpret its behavior throughout its complete life cycle.
Most commonly, data scientists and other Artificial Intelligence professionals create a digital twin or a virtual replica to study how an actual IoT device or system will behave under different circumstances. In other words, they use digital twins to record and test simulations before the actual devices are built and stationed in their designated areas of application. A digital twin acts as a bridge between the digital and the physical worlds.
In simple layman terms, think of digital twin as the initial prototype or blueprint of your internship project which you improve over time to create a fully-functional project by the end of your semester.

As is the usual case with most of the technologies backed by the Internet of Things and Artificial Intelligence, creating digital twins enables the products and devices to be easily reprogrammed in the course of operation. This is usually achieved with the help of sensors that are part of the prototype. For better understanding, let us take the example of a jet engine. A digital twin can be used to collect data and measure the performance parameters of the jet engine. Based on the data collected, improvements can be made and newer versions of the engine can be created, as and when necessary.
Due to the large amounts of data being digitized, the Digital Twin technology enables data to be computed, transmitted and stored in a fast and cost-efficient manner. Yet another revolutionary characteristic of developing a digital twin is that it can be shared among large groups of people, without any geographical or time constraint.
Uses of Digital Twin Technology
Some of the important and widely popular uses of the Digital Twin technology is the design and maintenance of the power generation machinery, most commonly turbines used in power generators and jet engines. Architects working in the field of Internet of Things are known to create and use digital twin blueprints to optimize the time and effort put into the development of AI and IoT-based devices.
With the help of the Digital Twin technology, the healthcare sector is already creating digital twins for patients. When coupled with IoT-based modern-day equipment and sensors, doctors in many parts of the world are now able to record and send health and fitness updates of patients to their respective digital twins.

TCS is constantly working on creating seamless convergence of both the physical as well as the digital versions of product prototypes. When put into action, the company has deployed digital twins of actual vehicles on roads and traffic-prone areas to address all kinds of challenges that are common to the entire automotive industry.
In the manufacturing sector, physical objects and machinery can be virtualized and seen as digital twins of the original machinery. The results and data sets obtained from working on the digital version of the machines/objects help in seamlessly integrating the results into the original physical entity. This way, companies can reap in the benefits from both the physical and the virtual entities simultaneously.
For example, Arctic Wind is a prominent mechanical firm in Norway that operates wind power plants. Checking the health of these wind turbines was a time-consuming, expensive and tedious process, given to the low temperatures and other unfavorable conditions. Hence, to monitor the overall health of the wind power plants, the company decided to install sensors on the wind turbines. By doing this, they can collect data and track the performance of the wind power plants. With the help of the digital twin, real-time data from the wind turbines can be collected, enabling employees to visualize any possible problem that can occur in the near future.
The concept of smart cities has been around for a couple of years now. However, to plan and implement such next-gen ideas of urban planning, builders and collaborators need to be absolutely sure of what they are doing! This is exactly where the Digital Twin technology kicks in. Creating a digital twin is a very popular part of urban planning methodologies, where the virtual twin captures real-time spatial data in 3D and 4D to study the behavior of modern geographical establishments. All this is possible thanks to the sensors embedded within cities and their digital twin counterparts.
For example, Augmented Reality (AR) is long being used to create reality maps, data from which is projected by professionals onto tabletops for further examination and correction.
