ØWhat is printed electronics.

•Revolutionary technique of making electronics components

•Printed electronics is based on new materials •Printed electronics is based on new materials and manufacturing processes.

•Simple way of fabrication of simple electronics components

ØWhy printed electronics

•Primary advantages of printed electronics include low cost•Additive Process (low waste)•Low Capital Investment •Low Capital Investment •Flexible form factor•Pe is suitable for solar panels, RFID tags, packaging•Potentially a more environmentally friendly process

ØDifferences between printed and conventional electronics

conventional electronics

Printed electronics

•high cost •Low cost

•In this may involve 7 •In this may involve •In this may involve 7 step of fabrication

•In this may involve 3 step of fabrication

•Rigid •Flexible

•High performance •Low performance

•High capital investment

•Low capital investment

ØProcess of printed electronics

ØSteps in printed electronics fabrication

Printing

Printing: is printing ofNanoparticle ink on substrate

Curing : is a photochemicalprocess in which high-

Curing

Laminating

process in which high-intensity ultraviolet light isused to instantly cure or “dry”inks

Laminating: is protectingfrom outer environment

ØPrinted Electronic Materials

Semiconductors:- is place main role in electronics and it necessary to form as ink.E.g.:- any Nanoparticle semiconductor inksemiconductor inkDielectric. This is a non-conductive(i.e. insulating) material used toblock or inhibit charge migration.E.g.:- Imide-Norbornene copolymer,Metal oxide

Conductors:- anywhere that charge always needs to be able to move freely.E.g.:-silver ink, conductive carbon ink, silver chloride ink.ink.

Substrate. This is thefoundation on which thedevice is builtE.g.:-plastic, steel or evenpaper

ØAdvantages

•Printed electronics include low cost•Flexible form factor•Ease of production•Ease of integration•Ease of integration•Lighter Weight•Rapid development cycles

ØDisadvantages

•Less integration capacity (not for VLSI)•Less life time•Easy to damage•Low power capacity•Low power capacity

ØApplications

•Solar cells•Printed LED•TFT•SENSORS•Printed batteries(Paper)•Printed batteries(Paper)•MEDICAL SENSORS•RFID•Smart Packaging•Touch Screens•Smart textiles•Logic and memory

•Other problem inusage of PV isflexibility can also beachieved

•Printed LED

•Using printed technologyflexible led will develop

•Organic light emittingdiodes (OLED) arediodes (OLED) arereceiving a lot moreattention in recent years,

•SENSORS •Printed batteries(Paper)•RFID

•Smart Packaging Flexible Displays Touch Screens

ØFuture of printed electronics

•IN Future printed electronics gives Color•And easy fabrication•Colorful wide area solar cells•Combination of other technologies in wide range of applications

· PE with nano technology· PE with NEMS· PE with robotics· PE with biomedical science

range of applications

ØConclusion

Printed electronics main advantage is very low cost soit is used in solar cells is good idea.Printed electronics will have implications across awide range of industries. Displays, RFIDs, sensors,and wearable or biocompatible electronic equipmentand wearable or biocompatible electronic equipmentare amongst the hottest research topics.
