Abstract
Methods for monitoring toothbrush technique are provided, for example a method including, while a toothbrush user is brushing his teeth, acquiring data indicative of motion of the toothbrush along its longitudinal axis, and, providing information about the data for display. Devices and systems for monitoring toothbrushing technique are also provided.
Claims24
A toothbrush comprising
- a handle, a neck,
- brush region extending from said neck, the brush region including brushing elements extending from a base,
- a motion sensor disposed in said brush region, and
- a data storage device for storing data that is sensed by the sensor.

A toothbrush comprising
- a body,
- a plurality of bristles extending from a portion of the body, and
- a sensor constructed to generate a time sequence of data associated with orientation of the toothbrush, the sensor comprising five strain gages, two of which measure movement in an x-direction, two of which measure movement in a y-direction, and the fifth of which measures pressure in the z-direction, wherein the sensor is capable of measuring pressure exerted by the bristles on a user's teeth in the z-direction, independently of pressure in the x and y directions that is indicative of motion, to enable a determination of the motion of the toothbrush independently of the force applied by the user to the teeth during brushing.
A toothbrush comprising
- a handle, a neck,
- a brush region extending from said neck, the brush region including brushing elements extending from a base, said base including an aperture, and
- a motion sensor disposed in said brush region, an elongated portion of said sensor extending through the aperture and into said brushing elements.
A toothbrush comprising
- a handle, a neck,
- a brush region extending from said neck, the brush region including brushing elements extending from a base,
- a motion sensor disposed in said brush region, and
- a rotation sensor constructed to measure rotation of the toothbrush.

A toothbrush comprising
- a handle, a neck,
- a brush region extending from said neck, the brush region including brushing elements extending from a base,
- a motion sensor disposed in said brush region, and
- a modem for transmitting data that is sensed by the sensor to a remote computer.
