Abstract
A shaver comprises a skin engaging portion and a cutting element, wherein the skin engaging portion comprises a force-generating member that can be selectively activated during use to increase or decrease a force of attraction to the skin of a user. The force-generating members may be electro-adhesive elements. A controller may be provided to selectively activate these elements.
Claims15
A shaver comprising a skin engaging portion and a cutting element, wherein the skin engaging portion comprises a force-generating member configured and arranged to generate a force of attraction to the skin of a user, the shaver further comprising a control element that can selectively adjust said force of attraction during use, characterized in that the control element comprises a sensor for measuring a parameter associated with the skin and a controller for selectively adapting the force of attraction in response to a measured property of the parameter.
(canceled)
The shaver according to claim wherein the parameter is indicative of a degree of doming of the skin ahead of the cutting element.
A method of controlling operation of a shaver comprising:
- moving a skin engaging portion of the shaver across the skin of a user in a direction of motion, whereby the skin engaging portion engages the skin and a cutting element engages hairs to be cut;
- adjusting a force of attraction between the skin and at least a region of the skin engaging portion during said movement, in order to adjust a degree of stretching of the skin ahead of the cutting element;
- characterized in that the method further comprises:
- measuring a parameter associated with the skin;
- and
- selectively adapting the force of attraction in response to a measured property of the parameter.
