Abstract

The development of stretchable and flexible electronics based on soft polymeric substrates requires novel approaches in the design, fabrication, integration, and packaging of passive and active electronic components. Here we demonstrate the fabrication, based on the use of supersonic cluster beam implantation and deposition, of a system consisting of a stretchable keyboard made by PDMS connected with a touch sensor and a matrix of LEDs printed on paper, through paper-based interconnections. The stretchable keyboard has conductive vias to electrically connect the top and bottom layers. Gold conductive films printed on paper are used to connect the keyboard with the electronic components that drive the LED matrix.
