Abstract
A personal care device () comprising an RF signal generator () for generating RF-frequency electromagnetic emissions for a cleaning or treatment function. The RF emissions may be output from a set of two or more RF electrodes () (e.g. electrodes) upon stimulation with an RF drive signal in a frequency range from 3 kHz to 30 GHz from an RF signal generator. The device further includes a controller () for detect a degraded functional state of the RF electrodes () via monitoring changes or variations in one or more electrical characteristics of the RF signal generator (), e.g. drift in one or more electrical characteristics from reference factory levels, or sudden changes in the characteristics, indicating a short-circuit. A response action can be generated based on the electrical characteristics meeting pre-defined criteria indicative of a certain degraded functional status, for example generating a sensory alert for a user or data output, or performing remedial action such as deactivating sensed defective or worn electrodes.
