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 (-> PSoC, ASIC ) ● wide range of different uCs 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 uC-based biomed 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 Adam blood glucose meter

I: Introduction – Microcontrollers Some examples for uC-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 Spo2 Module

Microcontroller In Research

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
