Microcontrollers in embedded biomedical Applications
Microcontrollers in embedded biomedical Applications: We want to have systems that : ● are reliable ● are small and lightweight ● have a low power consumption These issues are critical when we deal with body implants
I: Introduction – Microcontrollers Some features / advantages of microcontrollers: ● ● ● 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 (-> PSo. C, ASIC ) wide range of different u. Cs available (memory, I/O, speed, busses, A/Ds ) ● data interchange using standard bus systems; -> various peripheral hardware accessible ● IDEs and toolchains for firmware programming / ● Simulation and high level languages -> 90% of the manufactured CPUs are not found in desktop PCs but in embedded systems, with growing areas of application: RFID, hidden "ubiquitous" computing, wearables, "smart environments", MEMS (micro electro-mechanical systems)
I: Introduction – Microcontrollers Some examples for u. C-based biomed devices / applications: ● various sensors or meters: Body temperature, Blood Pressure, Blood Sugar Level, … ● Implants and prostetics ● Pacer makers (for heart, breathing, . . . ) Adam blood glucose meter ● functional Electrostimulation ● Orthesis and artificial limbs ● Biosignal acquisition equipment www. heartratemonitor. co. uk
I: Introduction – Microcontrollers Some examples for u. C-based biomed devices / applications: ● 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 and Actuators for stationary medical equipment Life-point defibrillator Spo 2 Module

Pace Makers and Functional Electro-Stimulation http: //www. hgcardio. com/HRhythm/Treatments/a_pacemaker_schematic. jpg ● current pacemakers have 5 -7 yrs. battery lifetime ● feedback loops -> adapt to physical needs ● multichannel stimulation and measurement electrodes
Parkinson relief from deep brain stimulation http: //www. firstscience. com/SITE/IMAGES/ARTICLES/dbs/man_pacemaker. jpg http: //www. parkinson-club-u 40. de/Hirnschrittmacher. htm ● lack of dopanine in substantia nigra ● hyper-activity of nerve cells ● pacemaker „inactivates“ those cells
Other Areas for FES - Implants / Pacer Makers http: //www. bio-pro. de/imperia/md/content/bioregionen/freiburg/neuropro. jpg http: //www. altenpflegeschueler. de/krankheiten/querschnittslaehmung. php Some examples: ● muscle activation / support ● gastrointestinal support ● breathing support ● chronic pain relief
