Determining a pressure associated with an oral care device, and methods thereof

A method for determining a pressure applied via an oral care device, the method comprising:

• determining, via a vibrational sensor, vibrational data emitted by the oral care device in use;
• determining, based on the vibrational data, an applied pressure of the oral care device for respective zones of a plurality of zones within an oral cavity of a user;
• determining, for each zone, an optimal pressure and a non-optimal pressure associated with the zone;
• and
• based on the applied pressure for a given zone being substantially the non-optimal pressure, causing the applied pressure for that zone to be substantially the optimal pressure by adjusting a motor intensity of the oral care device;
• wherein the vibration sensor comprises a microelectromechanical systems (MEMS) device configured to directly measure a mechanical vibration to determine the vibrational data, the MEMS device being a microphone configured to determine the mechanical vibration emitted by the oral care device;
• wherein at least one zone of the plurality of zones has a different optimal pressure and non-optimal pressure than another of the plurality of zones.

An oral care system comprising:

• an oral care device comprising:
• a head comprising cleaning elements;
• and
• a vibrational sensor configured to determine vibrational data emitted by the oral care device in use, the vibrational sensor comprises a microelectromechanical systems (MEMS) device configured to directly measure a mechanical vibration to determine the vibrational data and an inertial measurement unit (IMU), the MEMS device being a microphone configured to determine a mechanical vibration emitted by the oral care device;
• and
• at least one processor operably coupled to the vibrational sensor, the at least one processor configured to:
• determine, based on the vibrational data, an applied pressure of the cleaning elements for respective zones of a plurality of zones within an oral cavity of a user;
• determine, for each zone, an optimal pressure and a non-optimal pressure associated with the zone;
• and based on the applied pressure for a given zone being substantially the non-optimal pressure, cause the applied pressure for that zone to be substantially the optimal pressure by adjusting a motor intensity of the oral care device;
• wherein the processor is configured to determine the optimal pressure and the non-optimal pressure via machine learning techniques.
