What is Digital Twin and How Will It Be Used in 2026? 

The backstory about the invention of a digital twin is a bit scattered. But let me try to put it as simple as possible for you: the early versions of the digital twin were used by NASA for the Apollo mission. It wasn’t called digital twin back then, and it was in 2010 when John Vickers coined the term ‘digital twin’. 

However, among the scientific community, Dr. Michael Grieves was the first one to formalize this technology in 2002 via his research on the product lifecycle.  

Anyway, What Actually is a Digital Twin? 

To explain it in the simplest words, a digital twin is a digital carbon copy of an object that physically exists. For example, it can be a Formula 1 car, a satellite, or even an RC plane. 

In fact, I first came across the term digital twin when I was working on a prototype for an RC plane. I used to connect to my high-speed WOW! Internet, load up the software, and improve the digital twin of my 3-D printed RC plane without making physical changes to my RC Airplane. That’s cool technology, isn’t it?

The digital twin of the airplane I made mimicked the exact behavior of its physical form under different circumstances. They look and feel the same; however, the only difference is that one is digital and the other exists physically. 

At this point, you might be wondering, how is it being used in the real world apart from my hobby of flying RC planes. Let’s talk about that as well. 

What Are Its Current Use Cases? 

Manufacturing

The most significant use case of digital twin technology is manufacturing. 

Let me walk you through it in detail. 

The most important goal of every manufacturing facility is to maximize efficiency. Engineers are working day in and day out to improve the efficiency without affecting the current capacity. They can’t test something better without stopping the current processes. 

That’s exactly why they rely on a digital twin of their processes. They can tweak things to see whether they improve efficiency or not on a digital twin without disrupting the workflow. 

Healthcare

Performing a surgery on corpses is fine, but surgeons can’t exactly know what will happen when some sort of drug is used on a patient during surgery. 

Well, they can know now by creating the digital twin of the organ, which replicates the same behavior of that organ when exposed to the drug. This will help them save more people and improve the overall medicines. 

On top of that, a digital twin of a hospital is also possible. This was actually the case during the pandemic when thousands of people were heading to the hospital, and managing them was a tough job. 

Philips created a hospital-level digital twin during the pandemic to efficiently manage beds in the ICU, CCU, and other wards at the hospital. They didn’t experiment on the actual hospital; they just created a digital twin, and when they were successful, they executed the plan for all the hospitals. 

Entertainment

Concerts in the West are massive. I have been to two Eminem concerts, and it was crazy. Thousands of people are in the same place. 

That’s why experimenting on an actual concert isn’t an option. Instead, their digital twin is created, and then it is implemented across the real concerts. 

Infrastructure

Do you know how Japan has managed to build skyscrapers that aren’t prone to tsunamis and earthquakes? They didn’t build them right away; millions of dollars were spent to create their most accurate digital twins. 

Their digital twins were thrown into multiple testing phases, and when they finally decided on one, they started building it. That’s how smart cities are actually built. 

These were the current use cases of digital twin. What about their future use cases? 

How Will Digital Twin Be Used in 2026? 

Customer Support

This is one of those aspects where digital twins will shine in 2026. Major corporations spend big bucks to ensure that their customers have after-sales support. This has been done via a full-fledged team of human-based customer support. 

Not only does it cost more, but it is prone to natural human errors. 

Their best alternative isn’t standalone AI but a mix of humans and AI support. A 3D avatar (basically a twin) of a highly effective customer support agent can be created, and with the power of AI, it can be used to improve customer support. 

TaaS

Corporations had to buy a 360 digital twin software to create their own digital twin. Well, the way software has been offered as a service, in 2026, a twin will be offered as a service. That’s why Twin as a Service (TaaS).

Training

Military training is extensive, and keeping tabs on the statistics was very inefficient until now. 

Whether it is military or any other department, employees can create a digital twin of themselves to understand where they actually lacked during the training. They can actually compete with themselves and improve them everyday through digital twin technology. 

The bottom line is that digital twin technology is super effective in improving almost every industry. The secret is revealed, and through TaaS, more industries will see inclusion of digital twins in their workflows in 2026.
