Introduction
The idea of digital twins is no longer science fiction – it’s a reality that exists and is fueling innovation across industries. Born in aerospace and manufacturing, digital twins have now invaded healthcare, energy, urban planning, and more. Where the Internet of Things (IoT), artificial intelligence, and big analytics converge, these virtual twins are empowering organizations with strong capabilities to track, analyze, predict, and optimize their businesses in ways that were once unimaginable.
Current market research suggests that the digital twin market is expected to expand from $7.48 billion in 2023 to over $96 billion by 2030, at a compound annual growth rate of nearly 40%. This exponential growth is indicative of the revolutionary potential that these technologies possess in the industrial sector.
As companies are increasingly under pressure to squeeze out maximum operational effectiveness, reduce costs, and spur growth, digital twins are becoming increasingly indispensable assets in their digital transformations. Digital twins provide virtual copies that enable companies to test scenarios, predict outcomes, and make decisions with unparalleled accuracy.
What are Digital Twins?
A digital twin is a virtual representation of a physical object, system, or process that is continuously updated with real-time data. Unlike static models, digital twins evolve alongside their physical counterparts, creating a dynamic digital mirror that captures the current state, historical performance, and predicted future behavior.
The concept consists of three basic elements that work together to create a comprehensive virtual model:
The physical elements are the objects, systems, or processes being modeled in the real world, equipped with sensors that gather and send data. The sensors may be as basic as temperature sensors or as advanced as IoT sensors that track multiple parameters at once.
Virtual components consist of computerized representations that take in and compute this data, thereby creating precise replicas. These representations involve physics-based simulation, statistical computations, and increasingly artificial intelligence to convert the information and predict future conditions.
Lastly, the bridge between the physical and virtual world allows for two-way data exchange, facilitating real-time synchronisation and feedback loops. Such a bridge is key to converting a static model to an actual digital twin, allowing changes in the physical world to be mirrored immediately in the digital world and to feed insights derived from the digital twin back into the physical world for action.
Take the case of a wind farm: For each of the individual turbines there is a digital twin that tracks performance data such as rotation speed, temperature, and vibration patterns. At Ørsted, the largest offshore wind developer globally, engineers employ digital twins to maximize turbine performance according to wind conditions. By tracking data from thousands of sensors, their digital twins forecast when equipment will fail and pre-book maintenance well ahead of time before expensive breakdowns. This has boosted energy output by up to 8% and prolonged the lifetime of turbines by years.
Use Cases in Different Industries
The versatility of digital twin technology has enabled its adoption across diverse sectors, each finding unique applications that address specific challenges.
Manufacturing and Industry 4.0
In manufacturing, digital twins serve as the backbone of Industry 4.0 initiatives. Companies implement digital twins to transform their operations in numerous ways that deliver measurable benefits to their bottom line
Siemens’ Amberg electronics factory in Germany is a great case of a cutting-edge use of digital twin technology in manufacturing. The factory has created precise virtual copies of its production lines, machines, and processes. The digital twins give engineers the ability to test changes in the production process virtually before implementing them on the factory floor. Before manufacturing a new product, Siemens tests the entire production process in the virtual environment so that one can detect and solve possible bottlenecks or quality issues before actual manufacturing begins.
Digital twins also have predictive maintenance capabilities that transform how businesses manage equipment maintenance. Digital twins in one of Bosch Rexroth’s German valve factories track the condition of key equipment based on vibration patterns, temperature fluctuations, and other factors. When the digital twin identifies patterns that suggest a failure is likely, it automatically schedules maintenance before a breakdown.
Healthcare and Medicine
The healthcare industry is experiencing a revolution through patient-specific digital twins and medical device twins, fundamentally changing how treatments are developed and delivered.
Scientists under the Dassault Systèmes’ Living Heart Project have developed detailed digital models of human hearts with individual patient information. Cardiologists at the Mayo Clinic use these models to study the possible effect of different surgical methods on blood flow and cardiac function in individual patients. In a particularly complicated case of a congenital heart defect, surgeons used a digital twin in a simulation of the evaluation of five different surgical approaches before selecting the best option. The patient recovered better than expected, with enhanced cardiac function after surgery compared to the original estimate.
The future of personalized medicine relies heavily on digital twins. Researchers at the UK’s Virtual Physiological Human Institute are developing comprehensive digital twins that model not just individual organs but entire physiological systems. These models can simulate how patients with specific genetic profiles will respond to different medications, potentially revolutionizing drug development and prescription practices.
Smart Cities and Urban Planning
Urban digital twins are transforming city planning and management by creating virtual replicas of entire urban environments that help stakeholders visualize complex systems and make better decisions.
Singapore’s Virtual Singapore initiative is arguably the most comprehensive digital twin city deployment anyone has ever undertaken. The digital twin combines real-time information from the city-state’s thousands of sensors, from traffic networks and energy grids to water systems and even building controls. Urban planners employ the digital twin to model the impact on air flow, sunlight exposure, and traffic patterns before construction begins. When designing a new subway line, engineers modeled several routes in the digital twin, their impact on the existing network and passenger routes.
Use of a digital twin in Boston is centered on climate resilience. The city has developed a comprehensive virtual model that replicates the potential impacts of sea level rise and intensified storms on various neighborhoods. The simulation integrates information concerning building characteristics, underground infrastructure, and topography to forecast patterns of flooding with accuracy. During Hurricane Sandy in 2012, neighborhoods that were labeled high-risk by the digital twin closely aligned with actual flooding events. Municipal officials now employ these models to determine priorities for infrastructure investment and to create tailored resilience plans for at-risk communities.
Energy and Utilities
Energy providers utilize digital twins to navigate the transition to sustainable energy sources, manage complex infrastructure, and improve reliability.
The Italian utility company Enel has developed digital twins of its electricity networks in several countries. Virtual copies control the flow of electricity through huge networks of thousands of kilometers of cable and numerous substations. When a severe storm swept through central Italy in 2020, the digital twin forecasted where outages were likely to occur by scanning wind patterns and vegetation models. This enabled Enel to dispatch repair crews ahead of actual service outages, thereby cutting the average outage duration by 30% compared with comparable past events.
In the water utility sector, London’s Thames Water uses digital twins to manage its aging network. The company created extremely detailed virtual copies of its underground pipe networks, with data on pipe age, material, pressure, and soil conditions. These simulations predict likely points of failure with 80% accuracy, allowing maintenance crews to replace vulnerable sections before leaks occur. This preventive approach has reduced water loss due to leakage by millions of liters annually and avoided enormous costs in emergency repairs.
