Production of wood-based electronics is one part of the development of printed electronics. The new manufacturing methods are significantly linked with printable electronics, which is going strong in the Oulu area. Different materials are optimized for the intended use of specific electronics: sustainability, recyclability, availability, environmental friendliness, and naturally also the price, which is affected by procurement, transport, and processing. Temperatures are being brought down and in many situations production at room temperature is already possible. Key guiding factors in the manufacture of electronics are the temperature of manufacture and the use of energy. Predictions of what kinds of applications wood-based electronics could be used for would be premature, but radio lenses that direct the signals of a radio transmitter have already been made of nanocellulose. The interfaces between communications technology and materials technology are interesting, and wood-based electronics are an important line of investigation, especially in a country like Finland where forest industry represents one fifth of the export of goods.
