Abstract :
This work presents equipment able to measure impedance of skin-electrode interface during the recording of biopotentials. This equipment is connected to a system previously developed in our laboratory for signal acquisition (SAASBIO-III). The aim is to assess the impedance and warn the operator if the measured values are not suitable. The electrode may be replaced to improve the measurements
