5. We want avoid sum critical issues, when deal with body implants.
Then,We want to have systems that,
 are reliable
 are small and light weight
 have a low power consumption
 Then, we want to use specific microprocessor is called microcontrollers.
 The primary difference between a microprocessor and a microcontroller
is that the microcontroller includes more supporting functions such as on-
board memory and I/O than the microprocessor.

7. They are small and flexible.
Easy to use ( most of the time )
Few external components and wires needed.
Low and ultra low power designs possible.
Wide range of different MCS available.
Data interchange using standard bus systems.
Using Simulation and high level languages.

8. Some examples for biomed devices /
applications
Various sensors or meters:
 Body temperature
 Blood Pressure
 Blood Sugar Level …

9. Implants and prosthetics
Pacer makers (for heart, breathing, ...)
Functional Electro stimulation
Orthesis and artificial limbs.
Biosignal acquisition equipment
Some examples for biomed devices /
applications

10. portable emergency equipment (defibrillator, ..)
Sports medicine.
Patient monitoring.
“Smart Homes", service robotics.
support of Communication for disabled persons.
wireless sensor networks / Body Area Network (BAN).
Sensors andActuators for stationary medical equipment.
Some examples for biomed devices /
applications

11. FES system is a computer controlled real time system.
Microcontroller with optimized software is basic
component in it .
Microcontroller to be chosen must have law power
consumption and required memory space

12. Pacemakers
 A pasemaker is composed of three part
A pulse generator
One or more leads
An electrode on each lead
 A pasemaker signals the heart to beat when the heartbeat is too
slow or irregular.
 It’s programmed demand only, so they do not compete with
natural heart beats.

13. Parkinson relief from deep brain stimulation
 Electrodes are placed deep with the brain through small holes in the
skull.
 The electrodes are commected by an extension wire to a programed
battery-powerded stimulator plased under the skin of the chest.
 DBS can help raduce the symptoms of tremor, slowness of movement,
stiffness , and working problems.

14. Other Areas for FES - Implants / Pacer Makers
 Some examples:
 muscle activation / support
 gastrointestinal support
 breathing support
 chronic pain relief
