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.
Claims18
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,
- wherein the force-generating member comprises an electro-adhesive element comprising at least two charge-holding electrodes connected to a voltage source to output a voltage to induce a local charge onto the skin of the user, the electro-adhesive element covered by an insulating layer to prevent contact between the at least two charge-holding electrodes and the skin,
- a control element configured to selectively adjust said force of attraction during use, wherein the control element comprises a sensor for measuring a parameter associated with the skin and,
- a controller configured to control the voltage source to change the voltage to selectively adapt the force of attraction in response to a measured property of the parameter.
3 more elements
A method of controlling operation of a shaver comprising:
- moving a skin engaging portion of the shaver across a skin of a user in a direction of motion, whereby the skin engaging portion engages the skin and a cutting element of the shaver engages hairs to be cut, wherein the skin engaging portion includes a force-generating member configured to generate a force of attraction;
- adjusting the 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, wherein the force-generating member comprises an electro-adhesive element comprising two charge-holding electrodes connected to a voltage source to output a voltage to induce a local charge onto the skin of the user, the electro-adhesive element being covered by an insulating layer to prevent contact between the at least two charge-holding electrodes and the skin;
- measuring a parameter associated with the skin;
- and
- selectively adapting the force of attraction in response to a measured property of the parameter by controlling the voltage source to change the voltage.

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,
- wherein the force-generating member comprises an electro-adhesive element comprising adjacent first and second charge-holding electrodes covered by an insulating layer to prevent contact between the electrodes and the skin and connected to a DC source such that the first and second electrodes may be oppositely charged with respect to each other,
- a control element configured to selectively adjust said force of attraction during use, wherein the control element comprises a sensor for measuring a parameter associated with the skin and,
- a controller configured to selectively adapt the force of attraction in response to a measured property of the parameter.
