Sirris Innovate 2011 - Smart products by printing, prof. Marc Van Parys, Sensortex/HoGent
Nov 22, 2014
Prof Van Parys reports about recent smart product democases using thermochrome and luminescent sensor inks. This resulted in fascinating new products like a baby suit that changes color (when wet), or a bikini that measures light intensity and indicates the amount of sun screen to apply to the skin.

Advantages Disadvantages
No solvent = inflammable Relatively expensive chemicals
Little energy required Monomers/oligomers
Fast drying/curingNo drying untill UV exposed
UV can cause burns - avoid skin contact
High production speeds Ozone generation
Thermosensitive Prints - Coatings (low flexibility)
Little space required Unknown Technology (for most)
Relatively low equipment cost - Less space requirements
- Modular - implementation in excisting coating line
Adhesion problems on some substrates (but canbe solved)
