In certain embodiments, a personal care device can include a housing, a functional assembly attached to the housing, a motor disposed within the housing and operatively connected to the functional assembly to move one or more components of the functional assembly, and a switch configured to move between at least two states.

A system and a method for adaptively releasing a lubricant or a cosmetic for a razor cartridge, a sensing unit detects a property of at least one of skin, air, water and a chemical agent in a region adjacent to the razor cartridge. A smart polymer provided on the razor cartridge is selectively responsive to a characteristic external stimulus by undergoing a physical or chemical change. A processing unit controls the release of the lubricant or the cosmetic by providing the characteristic external stimulus to cause the smart polymer to undergo a change. The processing unit compares the detected property to a reference threshold parameter and determines whether to provide the characteristic external stimulus to the smart polymer based on the comparison, thereby generating the lubricant or the cosmetic. The determined level of depletion of the smart polymer is indicated by a light, aural, or haptic indication.

The present invention relates to an electric personal care apparatus comprising a skin contacting portion configured for contact with skin of a user. The skin contacting portion comprises a porous and compressible material. The porous and compressible material is configured to hold a fluid by capillary forces. The porous and compressible material is configured to be compressed due to pressure contact of the skin contacting portion with the skin of the user, and configured to release the fluid onto the skin of the user when the porous and compressible material is holding the fluid and being compressed.
