Abstract:
1. A safety razor comprising: a handle and a cartridge selectively detachable from the handle, the cartridge comprising at least one blade with a sharp cutting edge and an expected shaving utility; a cartridge release mechanism arranged to move in a first direction coupled to the handle and configured to detach the cartridge from the handle in response to an action performed by a user; and a sensor within the razor comprising a pin member projecting from the cartridge release mechanism, the pin member momentarily interacts with a resistive member only during detachment of the cartridge from the handle the resistive member configured to generate a signal in response to the momentary interaction of the pin with the resistive member, the resistive member comprising a polymer having particles of metal or semi-conducting material dispersed therein wherein the resistive member has a first level of conductance when quiescent convertible to a second level of conductance in response to the action applied by the cartridge release mechanism.
