Abstract
The present invention relates to a device for picking up at least one impedance measurement in a physical, physicochemical and/or biological process including: a probe suitable for being applied to an environment containing biological cells, said probe including a body, a first group of at least one electrode and a second group of at least one electrode, a conditioner suitable for outputting signals showing the electrical impedance of said environment between the electrode(s) of the first group and the electrode(s) of the second group, said conditioner being electrically referenced to a measurement mass, a connection means suitable for connecting the probe and the conditioner, characterised in that said probe also includes a third group of at least one electrode electrically connected to a reference electric potential.
