More Information
Summary:A personal care device comprising functionality 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 emitter elements (e.g. electrodes) upon stimulation with a drive signal from a signal generator. The device further includes means for monitoring a functional status of the emitter elements via monitoring changes or variations in one or more electrical characteristics of the signal generator circuit, 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.
