The technology we use was developed at TU Berlin in the frame of the European Project STELLA. The goal of the project was the integration and electrical interconnection of commercially available components into a stretchable matrix material in order to realize stretchable electronic systems. The technical solution from TU Berlin is based on the use of polyurethane as stretchable substrate material. For the realization of the systems established techniques for fabrication, component assembly, encapsulation and electrical testing of conventional printed circuit boards are used.
By using established technologies enables a fast and cost effective realization of stretchable systems. Potential products and application fields are medical sensors, automotive and fashion design.
Stretchable electronics can easily be integrated into textiles by lamination. Various methodologies for the electrical interconnection to textile electronics and peripherals, like power supply are available: embroidery, crimping and press buttons.
