Presents a Seminar on:

“Flexible Electronics”

FLEXIBLE ELECTRONICS

Outline:• Introduction to Flexible Electronics• Focused areas:

• Flexible Circuits boards (FCB’s)• Flexible electronic components• Flexible displays

• Manufacturing technology in brief• Future of flexible electronics• Applications• Advantages and disadvantages• Conclusion


What is flexible electronics ?

Flexible electronics, also known as flex

circuits, is a technology for assembling

electronic circuits by mounting electronic

devices on flexible plastic substrates.


Flexible Circuit boards


Flex circuits are made up of

flexible plastic substrate

usually polyimide, Polyester or

thin sheets of glass

Flexible electronic components

Electronic components such as transistors

are being made from silicon nanomembrane

usually called TFT’s(thin film transistors).

Flexible resistors & capacitors structures

are shown diagrammatically usually called thin

flim resistors and thin flim capacitors


Resistor Capacitor


Lithium-ion flexible battery

Non volatile Memories


Flexible Displays

Organic light-emitting diodes (OLEDs) are

normally used instead of a back-light for flexible

displays.


Manufacturing of flexible circuits & devices

For the manufacturing of flexible electronics

“Roll to Roll” (R2R) processing inkjet printing

and soft lithography process is used.


Steps of R2R processing

Layers materials and their thicknessBase material or substrate

1.Flexible polymer flim2. Polyethylene terephthalate3. Thin glass sheet

12-125 µm

Conductive path 1. Copper foil2. Polyester3. Graphene

200 nm


Market Growth• The market for flexible, printed, and organic large-area electronics

is rapidly growing. Currently estimated at over $200M, the global

market is expected to increase to a $800M market by 2020.


Future Flexible Electronic products

Applications• Automotive field.

• Space crafts.

• Foldable displays.

• Military.


Flexible solar cells

Flexible outwears

Samsung key note CES


Stretchable Lithium ion battery


Developed by University of llinois at Urbana

ADVANTAGES

light weightSmaller dimensions

requiredSpace savingFoldable and bendable

DISADVANTAGES

Initial investment may be expensive

Integration of components would be challenge for engineers

Precision machines required


ConclusionFlexible electronics in future will play a part in

field of security, entertainment and may lead to

innovative applications

The demand for flexible electronic products at

present may not be noticed but upto 2020 there

would be huge demand and preference will be given

to the flexible products in market
