  • Pressure-sensing toothbrush
    Patent number: 5876207
    Abstract: A toothbrush including a head, a tuft of bristles positioned at the head, a piezoelectric film disposed within the head in such a way that a force applied to the tuft of bristles generates voltage in the piezoelectric film, and an indicator for indicating that a predetermined level of voltage is being generated in the piezoelectric film. Preferably the tuft of bristles is able to "float" within the head of the toothbrush. The indicator is constructed to provide a signal that is perceivable by a user of the toothbrush (e.g., a visible signal or an audible signal).
