Published on

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.

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