摘要
An electric toothbrush head includes a bristle field with responsive bristles that decrease in stiffness in response to excessive brushing pressure. The toothbrush head also features a mechanical force-protection mechanism, which induces a reversible displacement of the bristle field in response to excessive brushing force. These features help to mitigate the effects of excessive force and provide a safer brushing experience.
