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 using techniques like transfer bonding or direct fabrication. Flexible electronics have applications in smart cards, electronic paper, displays, and wearable devices. They offer advantages like thinner profiles, lighter weight, and better energy efficiency compared to rigid circuits. However, flexible electronics also face challenges like higher costs and the need for precision manufacturing methods. With continued advances, flexible electronics are expected to greatly impact the electronics industry and enable new applications.

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
