Shaving systems and methods
A shaver, comprising a handle body, a cartridge coupled to the handle body, the cartridge including a skin care treatment head, a transducer configured to generate electrical energy from mechanical energy, thermal energy, sound or acoustic waves, magnetic field and/or radiofrequency energy; and a battery configured to receive electrical energy generated by the transducer.
1. A shaver, comprising:
a handle body;
a razor cartridge coupled to the handle body, the cartridge including a skin care treatment head; and
a transducer configured to generate electrical energy from mechanical energy, thermal energy, sound or acoustic waves, magnetic field and/or radiofrequency energy; and
a battery configured to receive the electrical energy generated by the transducer.
2. The shaver of claim 1 , wherein the mechanical energy is generated by vibration or motion of the shaver during use.
3. The shaver of claim 1 , further comprising:
a pusher operably connected to the cartridge and the transducer, the pusher being movable relative to the handle body; and
an accelerometer configured to capture the mechanical energy generated by the motion of the pusher and/or the motion of the shaver, wherein the accelerometer is configured to transfer the captured energy to the transducer.
4. The shaver of claim 3 , further including a magnet coupled to the pusher, wherein the transducer is configured to generate electrical energy from a magnetic field generated by motion of the magnet.
5. The shaver of claim 1 , wherein the mechanical energy is generated by an external pressure applied to an outer surface of the handle body.
6. The shaver of claim 1 , wherein the transducer includes a piezoelectric element.
7. The shaver of claim 1 , further including at least one of a sensor, processor, or transmitter coupled to the battery.
8. The shaver of claim 7 , wherein the at least one of a sensor, processor, or transmitter is configured to receive electrical energy from the battery and/or directly from the transducer.
9. The shaver of claim 1 , further including an indicator configured to provide a status of the battery.
10. The shaver of claim 1 , further including a notification element configured to provide a notification of a change in a status of the battery.
11. The shaver of claim 10 , wherein the notification element is configured to provide an audio, visual, or haptic notification upon the change in the status of the battery.
12. The shaver of claim 1 , further including a USB port.
13. The shaver of claim 1 , wherein the skin care treatment head comprises one or more blades, an exfoliation head, a sponge, and/or soap.
14. The shaver of claim 1 , wherein the mechanical energy used by the transducer to produce energy, originates by a physical activity of the user.
15. The shaver of claim 1 , wherein a connector assembly couples the handle body with the razor cartridge, the connector assembly being configured to and dimensioned so that the razor cartridge is able to move about and along multiple axes.
16. The shaver of claim 15 , wherein a biasing element configured to bias the razor cartridge back into a rest position with respect to the handle body after use is provided spaced apart from the connector assembly.
17. The shaver of claim 1 , further including an actuating member configured to enable actuation of a PCB control circuit mounted inside the handle body, the PCB control circuit configured to control generation and frequency of vibrations in the shaver.
18. The shaver of claim 1 , wherein one or more walls of the handle body are made of a compressible material including a piezoelectric layer such that when pressure is applied to the compressible material during shaving a compression force is applied to the piezoelectric layer thereby generating electrical energy.
19. A method of harvesting energy from a shaver, wherein the method comprises:
providing a shaver according to claim 1 ; and
moving the razor cartridge with respect to the handle body.
20. The method of claim 19 , further comprising providing protocols for purposeful user-induced charging of battery before using the shaver thereby providing instructions to the user to perform a physical activity with the shaver to enable the transducer to produce energy to charge the battery.
