2. • A small generator creates electricity which travels
through small cable to the brain, where electrodes carry
out the simulation. Bionic brains can help with
Parkinson's dieses
• Skin is one of the hardest to replicate because of pressure
temperature and pain are hard to replicate. Sensor would
send signals to a computer. It will be years before they
can attach e-skin to limbs and to the brain until electrical
advances are made.
Brain and Skin
3. • To replace a damage eye a light sensitive chip which is
attached under the retina which sends electrical pulses to
the brain. Patients after fitted with the chip were only able
to see basic shapes.
• The bionic ear, Cochlear implants is a device that sends
electrical impulses directly to the brain.
• In a normal ear their are thousands of tiny hair in the
cochlea that send electrical impulses to the brain.
Ears And Eyes
4. • The whole hear is replaced by two chambers which are
attached to pump that allows blood in and out
• Theses artificial hears are made out of plastic and
simulate a real heartbeat.
• In a artificial pancreas a sensor detects the amount sugar
in the blood which is sent to a computer which calculates
the insulin does which is then sent to the blood cells.
Heart and pancreas
5. • In a bionic arm muscles generate small electrical signals
which can be picked up by sensors on the skin which
generate specific movement.
• In a bionic leg seven sensors including a gyroscope and
an accelerometer detect the leg in a three dimensional
appearance, an on board computer operates hydraulic
valves which control the leg's movement.
• The artificial legs can respond to climbing walking
backwards and different speeds.
