Nanotechnology

Nanotechnology begins when structures become so small that they are no longer visible to the naked eye—and materials suddenly develop new properties. “Nano” primarily describes a scale: a nanometer is one-billionth of a meter. What matters, however, is not just the small size itself, but what it makes possible. Surfaces can become more reactive, materials more stable, coatings more functional, particles more conductive, and optical properties can be specifically modified. This is precisely why nanotechnology is found in so many applications today, even if it isn’t always explicitly referred to as such—for example, in functional surfaces, catalysts, battery materials, sensor technology, medical technology, displays, and semiconductor processes.

Nano- and microsystem technology

Nano- and microsystems technology makes it possible to perform complex functions in the smallest of spaces. While the focus used to be primarily on microsystems technology, structural dimensions, manufacturing processes, and levels of integration have continued to evolve. Today, the focus is on miniaturized systems in which sensors, actuators, electronics, materials, and data processing work together. They measure, control, regulate, and respond—often without the user even noticing. Whether in smartphones, vehicles, medical technology, production facilities, or smart infrastructure, many applications seem to work “as if by magic” because, behind the scenes, highly integrated systems precisely capture information and translate it into actions.

Innovative Materials

Materials are the foundation of nearly every technical innovation. From the Stone Age through the Bronze Age to the Silicon Era, materials have demonstrated just how profoundly they shape technological development. Even today, progress often begins with materials: semiconductors enable microelectronics, lightweight construction materials reduce weight and energy consumption, functional surfaces create new properties, and high-performance materials make extreme loads manageable. The BMFTR points out that around 70 percent of all product innovations are based on improved or novel material properties—a strong argument for viewing materials not as a supplier detail, but as a key strategic technology.

Photonics

Photonics uses light as a tool, a carrier of information, and a precision instrument. It encompasses technologies that generate, control, measure, or harness photons for various applications—ranging from lasers, optical sensors, and imaging to fiber-optic communications, displays, medical technology, manufacturing, and quantum technologies. The BMFTR describes photonics as the science that studies photons and translates that knowledge into technologies; together, photons appear as beams of light or laser beams. Photonics is particularly relevant in industrial manufacturing: Lasers have become versatile tools for precise, flexible, and resource-efficient production processes.
