TRANSDUCERS

  • This block deals with biomedical sensors and transducers.
  • The classification criterion that has been used in this course for the sensors and the transducers is based on their physical operation principle.
  • Resistive, optical or photoelectrical sensors and transducers, used in the temperature data and optical signals acquisition, are studied in this board.

AMPLIFIERS

  • The electrical signals, generated by sensors, is usually at a low level of amplitude and power, so that it is necessary to amplify it before its transfer, further analogue or digital processing and visualization.
  • In this course we will study the characteristics of the pre-amplifiers and amplifiers for the processing of biomedical signals.

FILTERS

  • In this course we will study the devices that allow the passage of biomedical signals with given characteristics, while attenuating those that do not comply with the required parameters.

PULSE CONVERSION INDICATOR

  • The events monitoring systems such as the frequency of the cardiac pulsations, the breathing frequency, etc., require that an analogue signal be converted to pulses and visualized on a display in order to be measured.
  • In this course students will study some circuits for analogue to pulse conversion, sound indicator and analog frequency meter. 

ECG – EEG – EMG

  • In this course we will study first of all the general specifications of the systems for the measurement of bioelectrical signals and subsequently the characteristics of some special systems.
  • This course comprises a further instrument, the ECG SIMULATOR, which is mandatory to provide power supply to the circuit and provides a simulated ECG signal for performing experimental activity

PULSE RATE

  • Concept of cardiac rhythm and typical values, in different subjects and in different conditions of the subject
  • Measurement of the cardiac frequency
  • The use of optical sensors
    • Comparator with hysteresis for the processing of the signal provided by the optical sensor
    • PLL, frequency dividers, PIC and their role in the measurement and visualization of the cardiac rhythm

CIRCUIT BLOCKS

  • Effects of breathing and exercising on the frequency of the pulsations
  • Effects of the temperature on the measurement of the frequency of the pulsations

TEMPERATURE AND RESPIRATION

  • Anatomy of the respiratory airways or tracts
  • Measurement of the body temperature
  • Temperature sensors
  • Temperature meter
  • Measurement of the respiratory frequency

CIRCUIT BLOCKS

  • Variation of the temperatures on the surface of the body
  • Advantages of the use of the electronic instrumentation with respect to the classic mercury thermometers for the measurement of the temperature
  • Main functions of the breathing system
  • Breathing frequency while relaxing and while exercising

GALVANIC SKIN RESISTANCE

  • Galvanic resistance of the skin
  • The function of the different skin layers
  • The electric characteristic of the skin
  • Behaviour of the human body at the passage of an electric current
  • Different types of measurements
  • Measurement of the resistance and of the  potential
  • Visual and audio signaling

CIRCUIT BLOCKS

  • Variation of the resistance in direct current of the skin with relation to humidity.
  • Recording of the changes of the galvanic resistance of the skin due to emotional or physical stimuli
  • Typical circuit that is used in the monitoring of the GSR

AUDIOMETER

  • Biophysics of sounds
  • Physiology of the auditory system: Perception, transmission and conduction of the sound
  • Diagnosis and evaluation of the acoustic deficit
  • Audiometer

CIRCUIT BLOCKS

  • Typical circuit of an audiometer
  • Graphical visualization of the hearing sensitivity of a patient in the whole frequency range

 T.E.N.S.

CIRCUIT BLOCKS

  • Mechanism through which electrical pulses are able to perform an analgesic effect
  • Typical circuit that is used in the transcutaneous electrical nervous stimulation

MAGNETOTHERAPY

  • Low frequency and low intensity magnetic fields and high frequency electromagnetic fields, where the magnetic component is almost equal to the electrical component, act on the whole body through an effect of substitution or activation of the missing electrical currents.
  • Consequently, they cause a fast regeneration of the bony and cutaneous tissues and considerably increase the immune defenses of the body.

ELECTROSTIMULATION

  • The electro stimulation, or the involuntary muscular contraction that is caused by electrical pulses, is a practice used both in rehabilitation and in sport or fitness.
  • It causes selective muscular contractions, more powerful and extended than those that are possible through voluntary efforts;
  • It allows, without physical efforts, amazing results such as the increase of the tone and of the volume of the muscles;
  • It increases the metabolism of the fats with consequent reduction of the adipose zones; it tones up the muscles and it progressively reactivates the functionalities of limbs that need reeducation

LASER THERAPY

  • I.R. is a beam of non visible, unidirectional and monochromatic light (since it is emitted in the infrared band) that transfers remarkable amounts of energy represented by photons.
  • This radiation does not produce heat, it does not alter the tissues and it is not felt by the patient that is under therapy.
  • It performs an anti-inflammatory and revitalizing action.

IONOPHORESIS

  • The ionophoresis is a technique that allows the substances in ionic form to penetrate from the surface of the skin to the deeper layers through a current.
  • These substances, named active principles, of different dimensions and molecular weights, become extremely effective because they act inside the skin tissues at higher concentrations.
