2. WHAT ARE SENSORS?
● A sensor is a device, module, machine, or
subsystem whose purpose is to detect
events or changes in its environment and
send the information to other electronics,
frequently a computer processor.
● A sensor is a converter that measures a
physical quantity and converts it into a
signal which can be read by an observe or by
an instruments.

3. WHAT ARE BIOSENSORS?
● A bio sensors is an analytical device, used for
the detection of an analyte,that combines a
biological component with a physiochemical
detector.
● It is an analytical device which converts a
biological response into an electrical signal.
● It detects, records and transmits information
regarding a physiological change or process.
● It determines the presence and concentration
of a specific substance in any tet solution.

4. WORKING OF BIOSENSORS:
● First biological
recognition element
which highly specific
towards the biological
material analytes
produces.

5. ● Second transducers detect and
transduces signal from biological
target - receptor molecule to
electrical signal which is due to
reaction occur.
● Third after transduction signal from
biological to electrical signal where
its amplification is necessary and
takes place and read out in detector
after processing the values are
displayed for monitor and
controlling the system .

6. TYPES OF BIOSENSORS:
Biosensors can be classified on their
working as follow:
● Calorimetric biosensors
● potentiometric biosensors
● Amperometric biosensors
● Conductometric biosensors
● Acoustic wave biosensors
● Optical biosensors

7. ARTIFICIAL HEART:
● The TAH replaces the lower
chambers of the heart, called
ventricles. Tubes connect the
TAH to a power source that is
outside the body. The TAH
then pumps blood through
the heart’s major artery to
the lungs and the rest of the
body.

8. ● The TAH has four mechanical valves that work like the heart’s
own valves to control blood flow. These valves connect the
TAH to your heart’s upper chambers, called the atrium, and to
the major arteries, the pulmonary artery, and the aorta.
● Once the TAH is connected, it duplicates the action of a
normal heart, providing mechanical circulatory support and
restoring normal blood flow through the body.
● The TAH is powered and controlled by a bedside console for
patients in the hospital.
● After they leave the hospital, people with a TAH use a
portable control device that fits in a shoulder bag or backpack
and weighs about 14 pounds. It can be recharged at home or
in a car.

9. ● The power is provided by internal
rechargeable battery.
● The battery is charged by wireless
energy transmission through the
coils above and under the skin.
● Internal controller monitors system
and controls pump speed.
( Internal controller
increases/decreases blood flow
based on blood oxygen levels)
How are they powered?
