Abstract: A force-sensitive toothbrush incorporates a bistable mechanism into the toothbrush handle. The mechanism can alert a user to excessive brushing force by changing shape in response to brushing forces exceeding a predetermined threshold. The mechanism can also automatically return to its original state when the brushing forces are lowered back down below the predetermined level. In one aspect, the mechanism may include a force-sensitive region having a principal beam and a secondary notched hinge buckling support beam located within the handle between the bristles and the gripping portion of the toothbrush. In another aspect, the force-sensitive region includes a principal beam and a secondary un-notched buckling support beam. In another aspect, the force-sensitive region includes a principal beam and a secondary support beam with a toothed clutch. These mechanisms can advantageously be molded into an integral toothbrush body using an injection molding operation.
