This paper presents a project-oriented laboratory. It is intended to provide an educational and research environment that stimulates innovative solutions in the growing field of Bioengineering. The authors took the advantages of the emerging technology and the increasing popularity of wearable biomonitoring devices, to teach students the key elements regarding the application of Information Technology in health monitoring. The students were involved in a complex project, along which they gain basic knowledge about the software development for biomonitoring, and apply it to effectively develop common structures and software applications. There are presented the stages of the laboratory work, with illustrations of the applications implementation at different levels of the hierarchy, starting from collecting data from the biomonitoring device, and finalizing with the data visualization by the end-user.

emphasized that a four-electrode probe made of gold was used for collecting the data, therefore a two-electrode impedance spectrum may not be fitted into our model. It is also well known that tissue is composed of many layers with different mechanical and electrical properties. The impedance probe is put in contact with the tissue sample, and then a small applied pressure is necessary for a good contact. Different applied pressure will result in different impedance spectra. All data were performed at very light applied pressure. In the case of the gelatin phantom, a very

long channel. After some time, the outlets would be opened to drain all the fluids in the channel. The next step is to inject the specific amount and type of drugs into the channel for cancer cells exposure while closing the single outlet and the two inlets. The cells would take some amount of time to absorb certain amount of drugs. Once that period is over, the rest of the liquid is taken out as a first testing sample for liquid chromatography – mass spectrometry (LC-MS) analysis. As a last step, the fresh medium is injected from the inlet to collect the popped

errors in measurements ( 147 ). Therefore, by successive measurements based on four electrode configuration, it would be possible to collect electrical data from several electrode pairs and consequently map the impedance of the subject under measurement ( 46 ). EIT measurements can be performed by applying different data collection methods ( 101 , 148 ) ( Figure 10 ) by which the current is injected and the voltages are detected: 1. Adjacent Drive or Neighboring method ( 149 ), 2. Opposite method, 3. Cross method ( 150 ), 4.Trigonometric or Adaptive method ( 151
