Formulation and printing of a new generation of PEDOT:PSS for
printed photonics applications.

Rosalie Lapointe, MSc student
Prof. Mario Leclerc (Université Laval)
The objective of this project is to produce an intelligent packaging using electronic
sensors to allow food products to be tracked in real time. In collaboration with INO,
we produced a printed temperature sensor using self-doped PEDOT:PSS analogs.

Shellac-Paper Composite Substrates for Impermeable Printed Electronics
Calum Noade, MSc student; Rahaf Hussein, MSc Student
Prof. Tricia B. Carmichael (University of Windsor)
Shellac is a natural bio polyester resin with unique resinous composition that is highly resistant
to molecular imbibition with water, leading to its high moisture- and gas-barrier properties
as a thin film coating or free-standing substrate.

Prof. Clara Santato (Polytechnique Montréal)
A viable route to reduce the carbon footprint of electronics is the development of
Sustainable Green Organic Electronics, using ubiquitous biosourced, biocompatible,
compostable and possibly biodegradable materials. Among the biosourced materials
available in nature, eumelanin is one of the most fascinating.

Green approach for fabrication of a cost-effective pH sensor
Mahtab Taheri, PhD Student
Prof. Jamal Deen (McMaster University)
In situ sol-gel deposition of RuO2 nanoparticles on the surface of graphene oxide

Water-processed flexible organic semiconductors
Cayley Harding, MSc student; Greg Bannard, MSc student
Prof. Gregory Welch (University of Calgary)
The water-based processing of a perylene diimide (PDI) organic semiconductor into
large area and solvent resistant films is reported. The compound, PDIN-H, is an
N-annulated PDI dye with a pyrrolic NH functional group that can be deprotonated
to render the material soluble in polar solvents.

Shahrzad Molavi, PhD Student
Prof. Thomas Szkopek (McGill University)
ISFET as (ion-sensitive field-effect transistor) is a semiconductor device that is used
for sensing ions in liquids. For an ISFET, having a low detection limit, high resolution
and low noise are important. A large area high-resolution ISFET for the detection
of lead ions in solution that uses graphene as a conducting channel is shown.
