Stretchable printed circuit boards go into series production
Dynamically deformable, expandable circuit boards serve a broad and rapidly growing field of application in the electronics sector. The relatively young technology is already ready for series production.

Electronic chips are not only smaller, but also more flexible - in the truest sense of the word. The EU research project
Conformable electronics are printed circuit boards made of polyurethane, which can be freely deformed in three dimensions after assembly. It can be stiffened, such as for customized component assemblies in the automotive industry or made permanently stretchable, such as for integration into functional textiles or for medical applications. The material base is a highly elastic PU film. Compared to the polyimides used otherwise, the special circuits are extremely flexible, twistable, and even repeatedly extensible.
Ultimately, this technology allows completely new designs to be implemented with curved lighting or input elements. The spectrum of applications ranges from medical technology, IoT and consumer electronics, Industry 4.0, automotive, and aviation. Typical applications currently include smart bandages, textiles, and wearables.
