Promotion of personal skills for project and team management

Speaker: Luis Ignacio Ballesteros Sanchez

This workshop focuses on project and team management skills needed for developing complex engineering projects, especially focusing on the challenges linked to the engineering design of biomedical devices. Successfully leading these projects, which requires working in multidisciplinary teams, depends not only on necessary knowledge and technical skills, but also on a wide set of personal skills including: communication skills, honesty, work ethics, flexibility, ability to work in harmony, loyalty, among others. This workshop will help participants to rapidly detect and solve problems when working in multidisciplinary and multicultural teams. It will also provide the teams from UBORA with resources for identifying key roles and for enhancing overall team performance, by taking advantage from individual skills and from mutual support. The participation of UBORA mentors is also highly recommended to create a debate for good practices in collaborative biomedical engineering projects and education.

Teaching resources:




Electronic Simulation of the Signal Acquisition Process

Speaker: Philippa Makobore

The workshop will focus on signal acquisition, specifically filtering and amplification of a signal. We have chosen this topic because signal acquisition is a key component in the design of biomedical devices. Physiological signals almost always need to be filtered and amplified before any meaningful information can be derived from them.

Teaching resources:

Speaker: Adrian Martínez Cendrero, Rodrigo Zapata Martínez

This workshop, in connection with the lesson on “Mass production and mass personalization of medical devices”, will present common tools for digitalizing human geometries and for designing and prototyping biomedical devices personally adapted to the patients. Optical imaging digitalization and related software reconstruction tools will be used during the workshop and teams will have the opportunity of scanning their components, in case some of the biodevices to be developed during the UBORA School may benefit from personalized approaches. Some cases of study linked to ergonomic supports and splints for articular pathologies will be presented.





Tracking movements

Speaker: June Madete

This workshop uses Biomechanics (body as a machine) principles to analyse motion. It will focus on calculating the orientation of a body in a three-dimensional space using a maker based system and show how 3 coordinates, x,y,z, can be transformed to motion of the Knee. In addition, compare the marker data to CT scans and Fluoroscopy and show how engineering principles can be applied to clinical data to.




Image processing

Speaker: Chiara Magliaro

Large amounts of biomedical and clinical data rely on images, and their processing and analysis are crucial for research as well as for diagnostic and therapeutic purposes. This workshop introduces the main concepts of image processing and analysis and their implementation using the Matlab Image Processing Toolbox.
After a quick theoretical lesson on image fundamentals, contrast enhancement and image segmentation, during the hands-on training you will use Matlab to implement a simple “Mood detector” from an image of a person. Workshop highlights:

  • Understanding of the concepts of Image Processing;
  • Practical sessions on Image processing, applied to face detection;
  • Implementation of an algorithm for detecting people mood from an image of a person.

Physiological signal acquisition using open source tools

Speaker: Ashwin K Whitchurch

This workshop will focus on using open source hardware to measure human physiological signals and derive not only basic vital signs such as heart-rate, respiration and SpO2, but also more advanced analyses such as heart-rate variability, stress, cardiac function and so on. Participants will have a chance to get hands-on on some open source hardware for this purpose and would leave with an idea about how to work with these devices to develop new applications.

Open source tools for usability analysis of medical devices

Speaker: Cinzia Bernardeschi supported by: Maurizio Palmieri

This workshop aims at presenting PVSio-web, an open source toolkit for design and analysis of user interfaces for medical devices. Using the toolkit, one can transform a static picture of a device into an interactive simulation that closely resembles the behaviour and visual appearance of a real system. A formal (i.e., mathematical) model defines the behaviour of the device. The model can be analysed systematically to check use-related safety properties of the user interface design, such as visibility of operating modes, ability to recover from use errors, and predictability of automated user interface functions. The students will learn how to use the toolkit to design the data entry system of medical device, which is typically used by clinicians to setup the therapy in the device. A set of already developed simulations based on real devices will be used as running examples.

A brief (practical) story of the pacemaker

Speaker: Mannan Mridha

To study the pacemaker signal with the help of Oscilloscope and calculate the energy it delivers, and design a pulse generator to deliver variable energy to stimulate heart with different needs and conditions.
Pacemakers are implantable medical devices that are prescribed for people whose hearts are beating too slowly or irregularly. A pacemaker stimulates the heart muscle with precisely-timed discharges of electricity that cause the heart to beat in a manner quite similar to a naturally occurring heart rhythm. A pacemaker consists of:

  • A pulse generator with battery and circuitry providing electrical energy and timing;
  • A pacing lead – an insulated wire that carries electrical impulses to the heart and information about the heart’s natural activity back to the pulse generator; one or two leads are used depending on the type of pacemaker prescribed. The idea is to demonstrate how the above is achieved by connecting a pacemaker pulse generator to an oscilloscope.
  • The signal delivered is presented on the Oscilloscope, and the amplitudes and the pulse width is measured.
  • Measurement of the Pulse width and Pulse duration should be done again, and this time by connecting a 50 Ohm resistor parallel to the oscilloscope and study the signal again, measuring the signal and the draw the pulse form. It is required to Draw the pulse form and Measure Pulse width, Pulse Amplitude and Calculate Time constant, RC.
  • Calculate the voltage drop on Rin, and current through Rin to find the value of Rin. Now, knowing the time constant, and Rin total, Calculate the value of Cin.
  • Calculate the total energy delivered by the pacemaker to 50 Ohm load.


The students can use the circuit above to deliver variable energy required to stimulate a heart, depending on the needs and conditions. The students can learn to:

  • Vary the pulse amplitude by changing R1 and R2
  • Change the pulse width by varying R3 and R4 to achieve the desired pulse width to get different energy for pacing.
  • Calculate the time constant T from oscilloscope by studying the signal from op pin 2 and comparing the result from the respective R C values.
  • Finally, calculate the energy it delivers in a certain time.
