Power systems for nail enhancements

Abstract

A nail enhancement includes a conductive substrate configured for placement proximal to a nail of a wearer and a color-changing layer comprising a chromic material that is integrated with the conductive substrate. A power source is in direct or indirect physical contact with the color-changing layer. The color-changing layer is activated to change appearance by the power source.

         6 . The nail enhancement of  claim 1  further comprising a power source positioned in a wearable device, the power source in wired electrical communication with the color-changing layer. 
     
     
         7 . The nail enhancement of  claim 1 , wherein the power source derives power from a wearer's body. 
     
     
         8 . A nail enhancement system comprising:
 a nail enhancement including:
 a conductive substrate configured for placement proximal to a nail of a wearer, 
   a color-changing layer comprising a chromic material, the color-changing layer integrated with the conductive substrate, and   nail wireless receiver connected to the color-changing layer; and   an external device comprising an external power source and a device wireless transmitter in communication with the nail wireless receiver;   
       wherein the color-changing layer is activated to change appearance by the external power source. 
     
     
         9 . The nail enhancement system of  claim 8 , wherein the external device is a wearable device. 
     
     
         10 . The nail enhancement system of  claim 8  wherein the external power source is a battery. 
     
     
         11 . The nail enhancement system of  claim 10 , wherein the battery is rechargeable. 
     
     
         12 . The nail enhancement system of  claim 11  further comprising a charging station for the battery of the external device. 
     
     
         13 . The nail enhancement system of  claim 8 , wherein the external power source derives power from a wearer's body. 
     
     
         14 . A nail enhancement comprising:
 a conductive substrate configured for placement proximal to a nail of a wearer;   a color-changing layer comprising a chromic material, the color-changing layer integrated with the conductive substrate; and   a power source comprising a bioelectric generator configured to harvest energy provided by a wearer's body, the power source in energetic communication with the color-changing layer;   
       wherein the color-changing layer is activated to change appearance by the power source. 
     
     
         15 . The nail enhancement of  claim 14 , wherein the bioelectric generator includes a piezoelectric material. 
     
     
         16 . The nail enhancement of  claim 15 , wherein the piezoelectric material is a deformable layer. 
     
     
         17 . The nail enhancement of  claim 14 , wherein the bioelectric generator is a thermoelectric generator that converts body heat from the wearer to electricity. 
     
     
         18 . The nail enhancement of  claim 14 , wherein the bioelectric generator includes a biofuel cell including an anode, enzyme, circuit, and cathode to process a body fluid into energy.
