What is a smart product ?

Smart materials and systems

- are able to sense and respond to the environment around them,

- have the potential to improve existing technology / add new functionalities to products,

- are miniaturised devices which are able to describe and diagnose a situation,

-may be energy autonomous and networked.

Surface functionalization

Replicated data-matrix structure in polymer

anticounterfeiting

Smarter because:- safer (traceability)

- integrated in the product

- optical (non-contact) reading



Surface functionalizationMicro-optical waveguides

(a few µm width, a few tens nm depth)

Smarter because:- micro-optics for sensing

- integrated in the product



Surface functionalization

Micro-replication of a Lotus leaf hydrophobic effect

Smarter because:- added functionality: self-cleaning effect

- no coating required (single material)

P.E. = not a substitute to classical electronics= complementary to classical electronics

Products - low cost - wearable (clothes)- foldable - ultra-thin- transparent - bio-compatible- stretchable - environment-friendly- …


Printed Electronics (P.E.)Based on the deposition (= « printing ») of polymer, organic,

inorganic « inks » onto any kind of substrates

Paradigm shift !


Printed electronics by Aerosol Jet Printing

Principle:

(1) Aerosol origination- Ultrasonic- Pneumatic

(2) Aerosol transportation

(3) Jet collimation and deposition

© OPTOMEC/Sirris

-High resolution: 10µm minimum feature size

-Maskless process: high flexibility and cost efficiency

- Large range of available inks

- Conductive, dielectrics, semi-conductiveand even biologic materials

- Compatible with low Tg materials(local laser sintering)

- Flat, flexible and even 3D substrates




Principle:

© OPTOMEC/Sirris

Smarter because:- directly integrated in the product

- any substrate (even 3D)

- customizable wrt application
