A non-woven material is thinner than paper and looks like a thin piece of textile. The material consists of fibres which are placed very close together on a breathable plastic coated foil. It is stretchable by up to 10 percent.
A stretchable, electrically conductive paste is printed on the material. Prints in graphite, graphic colours and lacquer are possible – all with stretchable properties and without crazing.
The stretchable sensors are screen printed on roll-to-roll printing equipment. During the production process, it is ensured that the non-woven material is handled without creasing, cracking or improper stretching, and without shrinking in connection with the curing of the conductive paste.
