Preface
Anuntappedopportunityintherealmofcommunicationandinformationtech-
nologyliesintinysmartdevicesthatwillsoonbeembeddedinalmosteverything
includingpaperandpackaging,thehumanbody,andvariouseverydayobjects.
These smart electronics may sense their environments, process information,
communicate by wireless means, and form ad hoc multihop spontaneous
networks,givingrisetoaworldwide-distributedsystemthatisseveralordersof
magnitudelargerthantoday’sInternet.Thisso-called“Internet-of-Things(IoT)”
willenableawiderangeofapplicationsandprovidenewbusinessopportunities
in many areas including medical and healthcare, safety and security, logistics
and inventory management, manufacturing, and automation. The electronics
as basic devices disappear or are cleverly hidden, but the functionalities are
availableinaubiquitousfashion.
To realize the vision of IoT toward a truly connected smart world, there are
three key enablers for such smart electronics: (i) extremely low-power or even
self-poweredintegratedcircuitsbasedonadvancedcomplementarymetal-oxide
semiconductor (CMOS) technology for computing, communication, sensing,
andperception;(ii)flexibleandlargeareaelectronics(LAEs)formultifunction-
ality and interfacing to the analogy world; and (iii) hybrid system integration
technologiesthatintegrateconventionalsilicon-basedCMOSchipswithprinted
materials/devices on flexible substrates. As silicon chip is inexpensive as mea-
suredbyperfunctionwhereasprintedelectronicsischeapasmeasuredbyper
area,webelievethatthehybridintegratedsolutionofsiliconchipsandLAEswill
bethemostpromisingsolutionforfuturesmartelectronicssystems.Thisbook
covers various aspects of smart electronic systems and summarizes our recent
researchfrommaterials,devices,systemstoapplications,withspecialfocuson
LAEsusingprintingtechniquesandintegrationtechnologiesforhybridflexible
systems.
