Microcontrollers Applications in medical areas:

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 (-> PSoC, ASIC )● wide range of different microcontrollers available (memory, I/O, speed, busses, A/Ds )● data interchange using standard bus systems; -> various peripheral hardware accessible● IDEs and tool chains 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),Biomedical systems.

Some examples for microcontroller-based biomedical devices / applications:

● various sensors or meters: Body temperature, Blood Pressure, Blood Sugar Level, …

● Implants and prostetics

● Pacer makers (for heart, breathing, ...)

● functional Electrostimulation

● Orthesis and artificial limbs

● Biosignal acquisition equipment

● 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 Spo2 Module

Microcontroller In Research(body area network[BAN])

Pace Makers and Functional Electro-Stimulation

● 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

● lack of dopanine in substantia nigra● hyper-activity of nerve cells● pacemaker „inactivates“ those cells

Other Areas for FES - Implants / Pacer Makers

Some examples:

● muscle activation / support● gastrointestinal support● breathing support● chronic pain relief
