This presentation gives a study analysis of powering and energy harvesting for internet of things.I made with the mindset that anyone should understood it who doesnt know about technical terms

11. But the problem is..

13. Energy
Harvesting

16. HELIOMOTE
FLECK
SOLAR BISCUIT SUN FLOWER

17. Thermal energy
Thermoelectric generator
Pyroelectric
technique
It generates electrical
energy when there is
temperature difference
Efficiency
5 to 7 %
TEG
Translates a thermal gradient
Between two surfaces into an
electric potential

18. Mechanical energy
Piezoelectric
Electrostatics
Electromagnetic
These are the techniques used to harvest
mechanical energy

19. RADIENT ENERGY
Large aperture power
Receiving antenna
Utilizable
DC power

20. Low power
hardware
Best way to improve battery life
Is to decrease the power consumed
by hardware components
Computation
System
Microcontrollers are the
Heart of the every embedded system
that communicates with real world
Heavily duty -
cycled mode
In which system is active only for very
short bursts of times separated by
long idle intervals during which system
can be placed in low power mode ,
sleep mode
Phoenix
processor
is an event driven
subthreshold processor
that has an sleep power
consumption of only 30pW

21. Communication
Subsystem
fact that device will communicate
with each other or with cloud based
services accessible through the
internet
Wireless
communication
Is more power hungry than other
Tasks such sensing or computation So
choosing an appropriate wireless technology
that Is power efficient is avital design choice
Despite its relatively high
power consumption ,wifi is
the preferred wireless
standard for many IoT
applications due to its near-
obiquitous nature
Its an advance version of well known
Bluetooth standard that was designed
for low power communication

22. Manufacturing Asset tracking
Radio
frequency
identification
Technology allows devices such
as batteryless smart tags to
operate using power harvested
from nearby readers RF
transmission

23. FUTURE
Ambient
backscatter
A novel technique that allows
Two battery less devices to communicate
With each other by backscattering existing
wireless signals from TVstations and cellular
transmission
