Listed below are some of the biomedical instrumentation projects that I have lead or directed.  Most of the projects were carried out at the University of Campinas with the participation of undergraduate and graduate students of electronic engineering before 1990 with the aim of transferring the technology to native industries.  The contribution of these young talents is gratefully acknowledged here. 

NOTE:  Not listed below are consulting projects that were carried out for specific manufacturers due to confidentiality limitations.
