Abstract:
A wet shave razor system comprising a razor head having one or more blades and a handle, wherein the razor head further comprises one or more in situ sensors comprising piezoelectric or piezoresistive material in a non-directly skin-engaging position for producing a feedback signal based on forces encountered during shaving, the handle further comprises one or more receptors for receiving the signal from the one or more in situ sensors, wherein conducting means extend from the one or more in situ sensors to the receptor to provide an electrical circuit between the one or more in situ sensors and the one or more receptors, wherein the one or more receptors comprise a feedback signal processing circuit which receives the feedback signal and the feedback signal processing circuit is connected to an indicator which comprises a light, a light emitting diode, a motion producing device, or any combination thereof which produces an indication in response to the feedback signal.
