low power we can get from harvesting energy from
environment. The phone takes advantage of
vibrations that occur when a person is talking in a
phone. The antenna connected to those components
converts that motion into standard analog radio
signal emitted by a cellular base station. This
process essentially encodes speech patterns in
reflected radio signals in a way that uses almost no
power.
We, a team of five members (Team Arsenal)
developed this application as a part of SMART
INDIA HACKATHON 2017 conducted at CVR
college of Engineering under the Ministry of
Empowerment of Persons with Intellectual
Disabilities.. To conclude with, We, Team Arsenal
are the PROUD CONTESTANTS of SMART
INDIA HACKATHON’17.
To transmit speech, the phone uses Vibrations from
phone to encode speech patterns in the reflected
signals. To receive speech, it converts encoded radio
signals into sound vibrations. The power can also get
from ambient light with a tiny solar cell-roughly the
size of a grain of rice. Phone sense speech, actuates
the earphones, and switch between uplink and
downlink communications, all in real time. It is
powered by either ambient radio signals or light.

BATTERY FREE MOBILE PHONE
Battery free mobile phone almost consumes very
low power. The components of phone receive and
transmit speech and communicate with a base
station. The phone calls use a few microwatts of
power which it gets from light or wifi signals. The
