Electrical characteristics of printed products determined in a snap
The pilot production environment of VTT Technical Research Centre of Finland
and PrintoCent, the community of printed electronics, in Oulu is being
complemented with roll-to-roll testing equipment. The equipment is used for
testing the electrical characteristics of printed electronics products,
enabling the measurement of the conductivity of printed components. Data can
thus be collected on the functionality of, for example, OLED screens and
organic solar panels.
The new testing equipment will speed up the measuring of components
considerably compared to the old manual method. It only takes three minutes to
measure all components in a square metre of material. Measurement data are
also saved automatically for the later, detailed scrutiny of individual
components. If necessary, the device can be used to measure all the components
in a printed roll, producing more detailed and comprehensive data than
previously possible on the functionality of roll components.
Oulu-based SME Probot Oy built the unique device according to specifications
provided by VTT. The input of Probot Oy to the design and construction of the
device will contribute to the growth in printed-electronics expertise in Oulu.
The idea of electronics produced by a printing machine is to create new
functionalities for products, including various electronic components and
diagnostic features. This production method enables the manufacture of large
production runs at great speed and with costs small enough for the components
to be incorporated in mass-produced products. Possible applications for the
technology are in home diagnostics, dispersed energy production, electronic
products, intelligent packaging and intelligent environments.
PrintoCent, the printed-electronics community established by VTT, the
University of Oulu and the Oulu University of Applied Sciences, provides
companies with a platform for agile development of completely novel industrial
products and enables industrial pilot production with minimal risk.
