Emerging technologies such as artificial intelligence and sustainable energy are reshaping how we live, work and interact with the planet. In this rapidly changing landscape, mechanical engineering plays a crucial role in developing and integrating these exciting innovations into our daily lives. Experts in this field use their knowledge of mechanical systems to design and build machines, engines and other tools.1

According to the United States Bureau of Labor Statistics (BLS), the demand for mechanical engineers will increase by 10% between 2022 and 2032.1 This article examines how mechanical engineers contribute to developing robotics, smart manufacturing and other emerging technologies.

Overview of Emerging Technologies

The phrase 'emerging technologies' refers to cutting-edge advancements in the early stages of development. Businesses and universities often dedicate many resources—such as funding for research, equipment and staff—to these innovations, which can then advance at an accelerated pace. They can transform industries and society by introducing more efficient processes and products.2

Recent examples, including artificial intelligence, flexible batteries and sustainable fuel, are revolutionizing our world: how humans generate ideas, power devices, travel and more. However, they also lead to new challenges, such as ethical dilemmas and public resistance to change.3

The Role of Mechanical Engineers in Emerging Technologies

Mechanical engineering experts have broad skill sets, enabling them to drive progress in many sectors. They analyze complex problems and use engineering principles and tools such as computer-aided design to develop creative solutions: longer-lasting batteries, innovative medical devices and power-producing machines, among many others. They also test emerging technologies and optimize the performance of new tools and mechanisms.1

These professionals frequently collaborate with experts in other disciplines. Multidisciplinary projects can lead to exciting new developments that require knowledge from several areas. For example, as reported in Forbes, mechanical engineers have already collaborated with experts in epidemiology and global health to solve sanitation problems.4 They also work with researchers in the automobile industry to create more aerodynamic cars and work in partnership with construction professionals to create more efficient heating and cooling systems.1

Robotics and Automation

Mechanical engineers play a pivotal role in the design process and maintenance of robotic systems. They integrate hardware with actuators, sensors and other critical components. One such pursuit involves building robots with sensors that detect light and activate specific behaviors, like adjusting position to avoid sunlight.1

Many industries rely on new and ongoing development in robotics and automation. During and since the worst of the COVID-19 pandemic, for example, hotels and hospitals have used sanitation robotics to disinfect rooms. One model—a disinfection robot controlled with a laptop or tablet—uses an electrostatically charged nozzle to spray positively charged chemicals onto negatively charged surfaces for highly effective cleaning. Its six-axis arm gives it a longer reach than other robots, so it can spray areas thought to be unreachable as well as high-touch surfaces such as light switches and doorknobs.5

Similarly, prompted by mounting pressure and growing demand for contact-free delivery of food and other items, care facilities and delivery services employed (and continue to use) robots to transport food, medication, infectious samples for testing, documents and other items to patients, medical professionals and customers in the general public.5

Artificial Intelligence and Machine Learning

In a 2023 article for the Plant Engineering website, product engineer Shreedhar Murthy Hebbur Subbaraju wrote, “In mechanical engineering, the use of artificial intelligence (AI) to automate routine tasks, optimize and streamline processes and improve quality control and testing precision is on the rise … When used correctly, AI can free engineers from menial work, allowing them to focus on alternative design and other more complex and interesting tasks. The use of AI also opens the door for engineering innovations, such as the development of smart and autonomous systems.”6

AI and machine learning (ML)—that is, training computers to learn from data to make predictions or decisions without being specifically programmed—have become deeply entwined with mechanical engineering. For example:7

  • Using data from sensors, machines and other sources, predictive maintenance of mechanical equipment uses machine learning algorithms to detect and predict potential failures in mechanical systems before they occur
  • AI and ML are crucial in the operation of autonomous vehicles (self-driving cars), helping them to navigate the environment while detecting obstacles, recognizing traffic signals, anticipating possible hazards and reducing fuel use by taking the most efficient routes
  • In this age of big data, the racing world can look to AI, ML and mechanical engineering to analyze data from past races in order to improve vehicle designs and automate production of new models

Sustainable Energy

It seems nearly impossible to overstate the importance of mechanical engineers in the development of sustainable energy. Consider their tremendous contributions in these areas:8

Solar Energy

Photovoltaic (PV) systems convert sunlight into electricity. Engineers are involved in the design and integration of solar panels, intent on improving their energy conversion efficiency, durability and cost-effectiveness. Further, they:

  • Develop advanced tracking systems that maximize the panels’ exposure to sunlight
  • Optimize heat dissipation mechanisms to prevent overheating
  • Explore innovative materials for improved solar cell performance
  • Contribute to the development of solar thermal systems that harness solar energy for heating and cooling applications

Geothermal Energy

Geothermal energy systems use the Earth's natural heat for electricity generation and heating. Mechanical engineers design and optimize geothermal heat pumps, power plants and other heat extraction technologies. They improve the efficiency of heat exchangers, drilling techniques and fluid circulation systems, which helps ensure optimal energy transfer and system performance.

Hydroelectric Power

Mechanical engineers design efficient hydroelectric power turbines and generators that convert the kinetic energy of flowing water into electricity. They work to make the turbines efficient and reliable and to minimize their environmental impacts. They’re also vital to the design and construction of dams, penstocks and other infrastructure components needed for harnessing hydropower.

Wind Energy

Mechanical engineers design and develop wind turbines, the windmill-like towers that have become symbols of renewable energy. They work to enhance the turbines’ efficiency, reliability and durability. They use advanced computational modeling, aerodynamic analysis and material science to optimize the shape, size and materials used in turbine blades, maximizing energy conversion and keeping maintenance needs to a minimum.

Energy Storage

In order to integrate renewable energy sources into the electrical grid, we need effective energy storage systems that address intermittency and meet changing demands. Mechanical engineers develop advanced energy storage technologies including batteries, compressed air energy storage (CAES) and flywheels. They work to enhance these storage systems’ energy density, efficiency and lifespans, enabling seamless integration and optimizing energy utilization.

Biomedical Engineering and Medical Devices

Mechanical engineers collaborate with healthcare professionals to develop better medical devices and prosthetics. For instance, in 2023, a team of engineers at Stanford University developed an electric “skin” that detects sensations like pressure and warmth; it can be used on prosthetic limbs to help patients interact with their environment more intuitively.9

Engineers can also apply mechanical principles to improve the efficiency of healthcare systems and procedures. Tools such as surgical robots improve patient outcomes by using complex mechanical operations to perform tasks like removing kidney stones.10 These creations help alleviate the staffing shortage many hospitals face today.
