An oral apparatus and a method capable of alleviating or curing snore and obstructive sleep apnea by applying a negative pressure through a mini oral interface to the oral cavity are provided. The polysilicon layer is positioned over the substrate. Extracted essential oil has also been shown to contain biologically active constituents that are insecticidal, nematicidal, fungistatic or which have antimicrobial properties. The apparatus also includes an external memory external to the processing unit and coupled to send configuration data to the configuration memory in response to a data feed signal outputted by the self-scrubber logic. If the first mode selection signal is activated, only the second control signal is activated.
