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 Adam blood glucose meter ● Biosignal acquisition equipment www.heartratemonitor.co.uk

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

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