Resum
The Discrete-to-Integrated Electronics group (D2In), at the University of Barcelona, in
partnership with the Bioelectronics and Nanobioengineering Group (SICBIO), is researching
Smart Self-Powered Bio-Electronic Systems. Our interest is focused on the development of
custom built electronic solutions for bio-electronics applications, from discrete devices to
Application-specific integrated circuit (ASIC) solutions.
The integration of medical and electronic technologies allows the development of biomedical
devices able to diagnose and/or treat pathologies by detecting and/or monitoring pathogens,
multiple ions, PH changes, and so on. Currently this integration enables advances in various
areas such as microelectronics, microfluidics, microsensors and bio-compatible materials
which open the door to developing human body Lab-on-a-Chip implantable devices, Pointof-
Care in vitro devices, etc.
In this chapter the main attention is focused on the design of instrumentation related to
amperometrics biosensor: biopotentiostat amplifiers and lock-in amplifiers. A potentiostat is
a useful tool in many fields of investigation and industry performing electrochemical trials [1],
so the quantity and variety of them is very extensive. Since they can be used in studies and
targets as different as the study of chemical metal conversions [2] or carcinogenic cells
detection, neuronal activity detection or Deoxyribonucleic acid (DNA) recognition, their
characteristics are very varied...
