TNO at Holst Centre (Eindhoven, The Netherlands) supports companies in the development of interactive surface technologies using structural electronics based on printed electronics that can be formed into any 3D shape, making rigid printed circuit boards a thing of the past. Printed circuit boards demand volume, cannot be adjusted in shape and are less cost-effective. With the approach TNO at Holst Centre has developed for structural electronics, both graphic and electronic parts are printed directly onto the backside of a substrate, creating a closed and smooth surface that contains all electronic functionalities. Touch buttons and icons can be located anywhere, on any surface and in any size. Technology design is therefore no longer restricted and pre-defined.
