Abstract:
Inkjet Printed Flexible and Disposable RF Electronics:
With the advent of wearable sensors and internet of things (IoT), there is a new
focus on electronics which can be bent so that they can be worn or mounted on non-planar
objects. Moreover, there is a requirement that these electronics become extremely
low cost, to the extent that they become disposable. The flexible and low cost aspects
can be addressed by adapting additive manufacturing technologies such as inkjet printing
on low cost plastic and paper substrates. This talk introduces inkjet printing as
an emerging new technique to realize low cost, flexible and large area systems
Prof. Atif Shamim – received his M.A.Sc. and Ph.D degrees in electrical engineering
at Carleton University, Canada in 2004 and 2009 respectively. He was an NSERC Alexander
Graham Bell Graduate scholar at Carleton University from 2007 till 2009 and an NSERC
postdoctoral Fellow in 2009-2010 at Royal Military College Canada and KAUST. In August
2010, he joined the Electrical Engineering Program at KAUST, where he is currently
an Associate Professor and principal investigator of IMPACT Lab. He was an invited
researcher at the VTT Micro-modules Research Center (Oulu, Finland) in 2006. Dr.
Shamim was the recipient of the best paper prize at the European Microwave Association
Conference in 2008. He was given the Ottawa Centre of Research Innovation (OCRI)
Researcher of the Year 2008 Award in Canada. His work on Wireless Dosimeter won the
ITAC SMC Award at Canadian Microelectronics Corporation TEXPO in 2007. He received
the best student paper finalist prize at IEEE APS conference in 2005. He also won
numerous business related awards, including 1st prize in Canada’s national business
plan competition and was selected for OCRI Entrepreneur of the year award in 2010.
He is an author/co-author of over 100 international publications and an inventor
on 13 patents. His research interests are in flexible and wearable wireless sensors
through additive technologies such as inkjet printing. Dr. Shamim is a Senior Member
of IEEE and serves on the editorial board of IEEE Transactions on Antennas and Propagation.
in the field of Radio Frequency (RF) electronics. The recent interest in inkjet printed
RF electronics is due to the latest developments in nano-particles based conductive
inks which can

achieve conductivities close to that of bulk metals. In addition to the conductive
inks, dielectric and semiconductor inks are also emerging. In this talk, a multilayer
process will be presented where dielectrics are also printed in addition to the metallic
parts, thus demonstrating fully printed devices. Many inkjet printed designs, primarily
for wireless sensing applications, will be shown. In the later part, it will be shown
how 3D inkjet printing of plastics can be combined with 2D printing of metals. The
promising results of these designs indicate that the day when electronics can be
printed like newspapers and magazines through roll-to-roll and reel-to-reel printing
is not far away.
