Transient Electronics: as per the name defines itself "lasting only for a short time"these devices can very well be used in covert operations where they can simply disappear after serving their purpose.Help in reducing e-waste.

Dissolution Behaviors and
Applications of Silicon
Oxides and Nitrides in

Recent development in
transient electronics
This paper explains how
transient circuit or device
can dissolve completely

7. Current research
Research in the area has explored the use of transient
materials to create dissolvable devices, such as transistors,
resistors and diodes.
Scientists have designed transient electronics as temperature
sensors, solar cells and miniature digital cameras
Now conducting further studies, centered on developing
degradable polymer based materials
In the past, only partial dissolution of transient electronics
was possible, however, total dissolution has been achieved

8.  MATERIALS FOR TRANSIENT
ELECTRONICS….
Silicon: Dissolution time for silicon id 10 days for 35nm chip
in volume of water of 0.4ml
ZnO: It is an alternate to silicon and other semiconductor
Mg and MgO: it is used as conductor and interlayer dielectric
due to their spontaneous reaction of water [Mg(OH)2].
Silk: Analog with crystallization & thickness it varies
dissolution time of chip.

9. Structure
Electrodes inside silk based on
nanometer thick sheet or
ribbons of silicon called
silicon nano membrane .
Dissipation rate is modified by
controlling the crystal
structure of silk and thickness
of silicon layer

10. Thermally Triggered Degradation of Transient Electronic Devices

11.  Devices
Colpitt rf oscillator
Environmental sensor
Cut way of inductor

12. DISAPPEARANCE TIME

13. Transient Electronics Based Led Circuit

14. Applications
Healthcare and Surgical
 Military and Industry
Decomposition of unwanted electronic gadgets

15. Advantages
Eco-friendly.
Enhance quality of life.
Reduce the amount of unwanted electronic components in
market.
Help in military to transfer the important information from
alien countries to home country and then circuit get’s dissolve

16. Disadvantages
Can not create large systems.
Designing of devices varies according to circuit
requirements.

17. As water comes in in contact
with water ,that part of circuit
that is in contact get’s dissolve

18. Conclusion
However transient electronics is definitely a technology worth
pursuing.
The fact that these devices enhance the quality of life greatly
and also have a very minimal environmental impact is very
promising for the future development of the technology.
Hence by introducing transience, transient electronics based
devices or sub-parts will become compost rather than trash.
 Furthermore, these devices can very well be used in covert
operations where they can simply disappear after serving their
purpose.

19. Future scope
Although much progress has been made in
developing new materials and devices for high
performance transient electronics there is still plenty
of opportunity to study and improve device
performance and fabrication techniques compared
with other devices.
In the future, the envision more complex devices
that could be adjustable in real time or responsive to
changes in their environment
Its market may increase in next few years.

the future of

not just
"smaller,
faster and
cheaper" but
also bent,
stretched
and
