Today I am going to talk about one of my college project which I performed for my internal assessments. I am going to talk about biodegradable electronics and their future scope. I read this information and related articles from ( https://www.researchgate.net/publication/242012066 ).

1. GUIDED BY : DR. AR BALLAL

2. GLOBAL E WASTE PRODUCTION IN 2018 WAS 49.8 TONS
PLASTIC ELECTRONICS -OLED DISPLAYS, ORGANIC
PHOTOVOLTAICS(OPVS),OFET
PLASTIC ELECTRONICS TAKE AROUND 500 – 1000 YEARS TO
DECOMPOSE
THEY ARE TOXIC TO PLANTS AND ANIMALS AND NONBIODEGRADABLE,
SO RESEARCH INTO NEW ELECTRONIC MATERIALS WHICH ARE
BIODEGRADABLE, BIOCOMPATIBLE IS NEEDED.
 THESE MATERIALS CAN BE CLASSIFIED AS
1. SUBSTRATES AND INSULATORS
2. SEMICONDUCTORS

3. materials of
bio – origin are
suitable
substrates for
the fabrication

have excellent
insulating
properties
which make
them suitable
as gate
electrode
insulators for
OFETs.

4. •low cost
•non-toxicity
•biodegradability
•biocompatibility and
bioresorbability for
biomedical application.

6. ENVIRONMENTAL MONITORING

8. IN VIVO IMPLANTS

9. DISSOLVABLE
GELATIN
CAPSULES

ELECTRONIC CIRCUIT FOR DRUG
DELIVERY AND DRUG STORAGE

10. RFID SENSORS ON FOOD

11. • CAROTENOIDS, GLUCOSE ETC ARE LINEAR 𝜋 – CONJUGATED
MOLECULES
• ACT AS HOLE TRANSPORTING AGENTS
• THEY ARE CHEAP, BIODEGRADABLE, BIOCOMPATIBLE, NONTOXIC
• MATERIALS LIKE 𝛽 – CAROTENE AND GLUCOSE CAN BE USED TO
MAKE TRULY GREEN ORGANIC FIELD EFFECT TRANSISTOR
(OFETS)
• HAVING MOBILITIES IN THE RANGE OF 1×10-4 CM2/VS
• WHICH IS NOT EFFECTIVE.

12. • SO MATERIALS LIKE ANTHRAQUINONES AND PERYLENE ARE USED
WHICH HAVE INCREASED MOBILITIES.
• INDIGO AND INDIGOIDS LIKE TYRIAN PURPLE ARE ALSO BEING USED
• APPLICATIONS LIKE AMBIPOLAR OFETS AND VOLTAGE INVERTER
CIRCUITS.

14. Biocompatible conducting materials has been an emerging field in
recent years
A multitude of biological pathways involve protons
So protonic/electronic interfaces are of importance while creating
biomedical devices which can be achieved conductors of bio –
origin
These materials of bio-origin have both electronic conduction
and ionic conduction
used in biomedical applications as well as in biodegradable
electronic devices

15. The first material that was used in an organic electronic
device was based on melanin
Melanin is a biological polymeric material responsible for
brown – black pigmentation in animals.
It was used in resistive switching elements, it has also been
used in various sandwich diode type devices.
Proton conducting material can also be used for fuel cell
applications.

16. Many conducting polymers are well suited to be used as
bioelectronics material as they can conduct both
electronic and ionic currents
Conducting polymers show excellent biocompatibility
Poly(3,4 – ethylenedioxythiophene) doped with polyanion
poly(styrenesulfonate) (PEDOT:PSS) is a Conducting
Polymer
Biosensing applications, and even in vivo studies.

17. Cell growth done on PEDOT:PSS films are reported to be free from toxicity.
PEDOT:PSS can be applied on living brain tissue as conformal polymer
electrodes for in vivo electrocorticography.
Interfacial conducting PEDOT nanotubes have been successfully used for
neural recording

18. A number of conducting polymers have been found to be biocompatible like
polyaniline, polypyrrole
Retain their conductivity and favourable mechanical properties flexibility in
biological systems
Non toxic and do not trigger any immune response

19. PEDOT NANOTUBES

20. • WE CAN CONCLUDE THAT THESE ORGANIC ELECTRONICS WHICH
ARE SUSTAINABLE, BIOCOMPATIBLE, BIODEGRADABLE,
BIORESORBABLE, NON – TOXIC
• THEY SHOW PROPERTIES ON PAR WITH OR SOMETIMES GREATER
THAN THE TRADITIONAL ELECTRONIC DEVICES.
• THE RESEARCH IN THIS FIELD IS IN ITS INFANCY BUT HAS SHOWN A
GREAT POTENTIAL AND CAN MAKE A HUGE IMPACT IN THE
FUTURE.
• THESE ORGANIC MATERIAL CAN GET DEGRADED BY SPECIFIC
STIMULUS OR BY CERTAIN ENVIRONMENT WHERE IT IS BEING USED
IN A CERTAIN TIME PERIOD.
• IT REMAINS IN THE ENVIRONMENT UNTIL ITS PURPOSE IS SERVED
