Techniques to "print" electronic circuits on to aircraft structures to reduce weight and boost data-collection quality are being developed by Airbus and BAE Systems.
Inkjet printing technology is to be used to deposit metallic and possibly ceramic materials, to build circuits on mechanical structures. Early work will see strain gauges and temperature sensors written on to aircraft surfaces, ending the need for plastic circuit boards. Direct printing will avoid the use of adhesives. These can interfere with sensor function and their removal could lead to more accurate data.
The research is investigating printing silver on to surfaces, but the variety of electronic components means there is a requirement to print other metals as well. Researchers are examining their properties and the effect they have on printer performance.
BAE says printed circuit life-cycle issues have to be investigated to answer questions relating to repairing a printed component and performance in extreme environments.
