Flexible electronics are a new type of electronics that are flexible like human skin, unlike traditional rigid circuits. They are made by mounting electronic devices on flexible plastic substrates. Two main approaches to making them are transferring completed circuits to flexible substrates or directly fabricating circuits on flexible substrates. Flexible electronics have applications in smart cards, e-readers, displays, wearables and more. They are lighter weight and consume less energy than rigid circuits, though manufacturing precision is currently challenging. Researchers hope flexible electronics will create new opportunities and eventually be cheaper to produce than today's rigid electronics.

1. FLEXIBLE ELECTRONICS

2. INTRODUCTION
• The electronic circuits has driven advances in
technology for over a half century.
• Today your cell phones, computer and even car
all rely on the engineering that has made
electronics circuit smaller, faster and smarter, but
circuits are mechanically limits they are rigid.
• Now several scientists are hoping
to change that as a new type of electronics
are developing that are FLEXIBLE as humans

3. WHAT IS FLEXIBLE
ELECTRONICS?
• Flexible Electronics, also known
as flex circuit.
• It is a technology for
assembling electronic circuits by
mounting electronic devices
on flexible plastic substrates, such as
polyimide, PEEK or transparent
conductive polyester film.

5. Manufacturing method
Flexible electronics are composed of Backplane and
Frontplane optoelectronics and Encapsulation that are
fabricated as fully integrated circuits on flexible substrates.
Two basic approaches have been employed to make
Flexible electronics:
1) Transfer and Bonding of completed circuits to a
flexible substrate.
2) Fabrication of the circuits directly on the flexible
substrate.

6. Materials for flexible electronics
A generic large-area electronic
structure is composed of
Substrate
Backplane electronics
Front plane
Encapsulation

7. SUBSTRATE
Flexible substrate are replaced by
plate glass substrates. Flexible substrate is
made up of:
 Thin glass
 Plastic film
 Metal foil

8. Backplane technology
• Backplanes provide or collect power
and signal to or from frontplanes
• Backplanes may be active or passive
• Backplane electronics include:
 Silicon Thin-Film Transistors
 Organic Thin-Film Transistors
 Transparent Thin-Film Transistors
Materials for Interconnects and
contacts

9. Frontplane technology
• Frontplane carry the specific optoelectronic
application.
• Frontplane materials of Display include:
Liquid Crystal Displays
Electrophoretic Displays
Organic Light-Emitting Displays
Sensors
Actuators
Electronic Textiles

10. FABRICATION PROCESS
BATCH PROCESS
• Flexible foil
substrates, cut
to sheets, will
be the drop in
replacement for
the rigid glass
plates or silicon
wafers.
ROLL TO ROLL
• Flexible electronics are
usually associated with
Roll to Roll processing.
• This Fabrication
includes solar cells
which is most desirable.

11. Applications
• Smart cards, Electronic paper
• Mobile communication
• Personal computers/portable displays/E-
readers
• Large area displays
• Wearable electronics
• Automotive applications
• Electronic billboards

12. Advantages Disadvantages
• Response time is
much faster
• Thinner Display
• Better contrast ratio
• Wider viewing
angles
• Light weight
• Less Energy
consumption
• Expensive
• Limited market
availability
• Integration of
components would
be challenge
• Precision methods
required

13. UPGRADING ELECTRONICS

14. Future Scenario
Flexible electronics will create a huge impact
and demand in the electronic industry in future.
Also, flexible electronics will be many times
cheaper than today’s electronics. Flexible
electronics in future will achieve the factors of:
 making Transistors smaller and Circuits
denser
 Getting a better grip on power consumption
 Developing new fabrication techniques and
tools
 High-density displays

15. Conclusion
Based on the current trends we outlined
the more likely technological Future needs
and discussed the potential exploits of
Flexible Electronics in various manners.
The research on Flexible Electronics may
lead to development of many innovative
applications.
