Sci-Fi-ology: Science Fiction and Tribology

Science fiction has long been a source of inspiration for technological innovation, pushing the boundaries of what is possible through imaginative storytelling. While many sci-fi inventions may seem fantastical, they often contain elements grounded in scientific principles.

Equally, a large number of sci-fi inventions simply wouldn’t work without tribological innovation or engineering considerations, which would play crucial role in translating these fictional technologies into reality. In this article, we will explore how tribology could theoretically influence and enable various sci-fi inventions. So let’s ‘engage’!


Frank Herbert’s Dune series introduced readers to the fascinating world of Arrakis, a desert planet covered in vast sand dunes. The iconic Ornithopters used by the inhabitants of Arrakis to traverse its harsh terrain exemplify the importance of tribology in science fiction. These aircraft-like vehicles rely on intricate wing-flapping mechanisms to stay aloft and manoeuvre through the abrasive desert sands.

In the real world, sand and other airborne abrasive particles can wreak absolute havoc on mechanical systems. Components subjected to such conditions must employ advanced lubrication and wear-resistant materials to prevent rapid degradation. In sandy environments, aircraft can encounter significant damage to plane turbine engine components from sand being sucked into the engine at incredible speeds – including damage to compressor rotor blades, vanes, and impellor wheels (all very important if you want to stay in the air for long). Dust and very fine sand can even be kicked up so high into our own atmosphere that they effect jetliners!

The Terminator

James Cameron’s Terminator series introduced us to the menacing yet sophisticated machines of the future, including the T-800 model. These humanoid robots are capable of human-like movements and interactions, showcasing advanced robotics technology. Tribology plays a critical role in making machines like the T-800 functional, as it enables smooth and precise articulation of their mechanical joints.

In robotics, tribological considerations are essential to reduce friction in joints and bearings. Lubricants, coatings, and materials with low-friction coefficients are vital for achieving life-like movements in robots. These principles have real-world applications in the development of industrial robots, prosthetic limbs, and even surgical robots which are helping the medical sector perform surgeries currently!

Star Trek

The Star Trek franchise has long captivated audiences with its vision of a holodeck, a virtual reality environment where users can interact with simulated worlds. One of the most intriguing features of the holodeck is its ability to provide haptic feedback, allowing users to feel the virtual objects they interact with. This concept has a direct parallel in real-world, touch-screen technology and the science of skin tribology.

In the development of touch-screen technology, tribology plays a crucial role in simulating the sensation of touch. Surface textures, friction coefficients, and tactile feedback are carefully engineered to create a realistic touch experience. Understanding the science of skin tribology has led to innovations in haptic technology, enhancing user experiences in gaming, virtual reality, and touch-sensitive devices. It even allows you to use your touch screen phones, tablets and other devices!


Christopher Nolan’s Interstellar took audiences on a mind-bending journey through space and time, featuring awe-inspiring depictions of black holes. These massive cosmic phenomena are surrounded by swirling accretion disks formed by immense gravitational forces and the friction generated by matter spiralling into the black hole.

While the accretion disks in Interstellar are a product of extreme astrophysical conditions, they are fundamentally driven by friction and gravitational forces. Understanding tribology principles can help scientists and astronomers better comprehend the complex dynamics of these cosmic structures. In practical terms, tribology also plays a role in the development of high-performance bearings and lubricants used in space exploration equipment.

Theoretical and imaginative sci-fi inventions often rely on principles grounded in real-world science and technology. Tribology serves as a bridge between these fantastical concepts and practical applications.

Whether it’s the challenges posed by sandy conditions, the precision of robotics, the intricacies of haptic feedback and skin interactions, or the expansion of knowledge of the cosmos, tribology underpins the feasibility and functionality of these advancements. As science and technology continue to advance, tribology will continue to play a pivotal role in making the seemingly impossible a reality!
