Humanoid robots, artificial intelligence, comprehensive automation: The Hannover Messe shows how rapidly Industry 4.0 is becoming reality. Behind the scenes, sweeping advances in materials science are leading the way – such as lightweight construction using high‑tech plastics.
The spectacular martial‑arts choreography during the visit of the German Chancellor to China, the new half-marathon record set for the first time by a non-human – what humanoid robots can now achieve is astonishing. Combined with artificial intelligence, science fiction is turning into reality.
This is true especially for industry, where the first machine‑like living beings are now being deployed. According to a recent study, up to 60 percent of manual tasks in areas such as production and logistics can, in principle, be automated. By 2030, several million humanoids could be installed.
The Hannover Messe makes clear to me why this is happening: the dynamic development is driven by the enormous innovative power of thousands of large and small companies. For example, on the opening day of the trade show, industrial supplier Schaeffler won the prestigious Hermes Award for an actuator platform – essentially the “muscles” in the joints of androids, enabling ever more precise fine motor skills.
Material Innovations for Technological Leaps
Automation and digitalization are the major technological drivers of industry, accompanied by the shift to electric energy. But we must also remember: all these robots, high‑tech computers, solar modules, wind turbines, and countless other forward‑looking applications always require equally innovative materials.
It is worth looking at a field that accelerates technological development significantly behind the scenes: lightweight construction. A key cross‑sectional technology that has long been underestimated. In Germany for example, the host country of the Hannover Messe, every second economic sector is connected to it. Lightweight construction directly contributes nearly four percent to Germany’s economic output and accounts for almost three percent of jobs.
It is therefore understandable that the Federal Ministry for Economic Affairs hosts the Lightweighting Summit at the fair every year. The motto of this year’s event, where I had the honor of giving the keynote: “Advantage Through Efficiency.” A topic that is becoming increasingly important for industry in times of rising competition and cost pressure.
Lightweight Construction with High‑Quality Plastics
In manufacturing, material costs are known to account for more than half of total costs. Increasing material productivity – meaning the ratio of value creation to material input – is essential to remain competitive globally. Resource‑efficient technologies such as lightweight construction are the key to it.

And high‑quality plastics are the ideal material for lightweight construction. Here, too, an epochal change is underway. AI and quantum computing are opening entirely new dimensions in development and production.
But even today, plastics impress with an unparalleled combination of excellent properties. They have low density while offering high strength. This makes it possible to manufacture components significantly lighter than, for example, metal. At the same time, plastics allow for low‑energy and cost‑efficient manufacturing processes.
However, economic viability is not measured solely by cost and material use, but also by functionality. And plastics excel here as well. Their high design freedom allows numerous features to be integrated – such as electronic elements like LEDs, sensors, or conductive tracks. These are also important material properties that drive lightweight construction forward.
Advantages for Efficiency and Resilience
But we cannot think about efficiency without considering a complementary economic core factor: resilience. Especially in times of volatile energy prices, lower energy demand becomes a strategic advantage – and those who rely on lightweight construction reduce it significantly: in production, in transport, and in operation.
At the same time, increasingly vulnerable supply chains benefit. Lighter components ease transport capacities, increase payload, and enable faster shifts between transport modes in times of crisis – from sea to air, from road to rail.
And finally, lightweight construction reduces not only weight but also complexity: function‑integrated components and modular structures simplify assembly and automation, reduce error rates, and make production systems more robust overall.
E‑Cars Benefit from Lower Weight
In light of this duality of resilience and efficiency, lightweight construction with high‑quality plastics is exactly the right approach to drive the transformation of key sectors. The strength of these advantages becomes especially clear in the mobility transition and the megatrend toward electric propulsion.
Just one hundred kilograms less on the scale reduces electricity consumption by an average of two to four percent. This extends the range without increasing battery size. Lightweight plastics such as polycarbonate reduce the high battery weight, protect the sensitive cells, and make vehicles more aerodynamic overall.
Electric cars have already arrived in everyday life, and humanoid robots will increasingly shape it. Without breakthroughs in materials science, without lightweight construction, and without the quiet performance of modern plastics, such technological leaps would be unthinkable. If we want to shape the future, this is exactly where we must begin – with the materials that make progress possible in the first place.
