Electrolysis device and method of operating the same

Abstract

Provided is an oral care device (100) for dental tartar removal. The oral care device comprises a control arrangement (102) configured to provide an electrical signal, for example a time-varying electrical signal. The oral care device also comprises a pair of electrodes (104A, 104B) for contacting an aqueous solution. The pair of electrodes are each connected to the control arrangement and configured to, responsive to said electrical signal, generate hydrogen ions from water in the aqueous solution to deliver within a subject's oral cavity, in particular to the subject's teeth. A variation of the electrical signal controls said generation of hydrogen ions. The thus generated hydrogen ions can lower a pH local to the subject's teeth and thereby assist to dissolve tartar thereon. The variation, for example time-variation, of the electrical signal may provide control over the generation of hydrogen ions which contrasts with, for instance, an uncontrolled generation of hydrogen ions via a non-varying voltage across the pair of electrodes provided by a direct current source. Further provided is a method of operating such an oral care device.
