Biopotentials measurements are essential for biological research and biomedical monitoring of excitable tissues. This chapter provides an overview of biopotential monitoring, from the biological basis to the circuit and ...

Biopotential measurements are very sensitive to electromagnetic interference (EMI) from power-lines. Interference conditions are mainly imposed by electric-field coupling, whose effects can be described by coupling ...

Obtaining a complete biopotential acquisition system suitable for the real-world use of an intelligent wheelchair is still an open problem without a satisfactory solution. It is perhaps the single block that may be hindering ...

Biopotentials are essential ssiignals that are immersed in the body like underwater currents in an ionic ocean. Electrodes allow their detection by transducing these ionic phenomena into electrical signg nals, feasible to ...

Sigma Delta analogue-to-digital converters allow acquiring the full dynamic range of biomedical signals at the electrodes, resulting in less complex hardware and increased measurement robustness. However, the increased ...
