Inkjet printing into new applications

I was just reading about an interesting new application for the inkjet printing device we all have at home. As the inkjet head can print micron small dots on different surfaces Panasonic has lodged a patent for an electronic spraying device to apply liquids on skin. This could become an alternative way to apply make-up and would allow for sensational make-up effects comparable to airbrush. Buying blush or foundation will never be the same once the product has been introduced!
But inkjet is also going into very different applications. Most of these applications use electronics. And because inkjet heads can print pico millimeters, integrated electronic circuits can be printed. Printing will go beyond simple colour and coatings printing, but will include printing of electronic conductive materials. In this way circuits and sensors can be printed on various substrates.
Probably the best known application is the integration of RFID on paper or film. When I visited the LabelExpo in Brussels this was one of the highlights of the fair. However most of the RFID tags were still made separately and not immediately printed on the substrate. Inkjet printing will allow to do that directly on the substrate offering higher flexibility and smarter paper. This paper can be used to develop smart products like packaging that integrates diodes that light-up when the date for consumption is approaching or paper that is sensitive to pressure or can light up.
It sounds like a science fiction application but is reality: the elaboration of cells, tissues and so called bio paper for veins in medicine
