A method for the realization of a surface grating of an integrated electrochemical sensor, consisting of a field effect transistor sensitive to alkaline earth metal surface substances as well as sensor.

摘要

The process is characterized in that the metal selected for the cathode (1) has a redox potential, constituting a reference potential that is substantially constant relative to water, which during electrolysis is greater than the effective reduction threshold of water, in order to avoid reduction of the latter. OH- ions, which are necessary for the nucleation of calcium carbonate, are produced during electrolysis only from oxygen dissolved in the water.
