Patent ID: 8156602

Claim:
An oral care device for generating a chemical agent in situ outside of the oral care device, comprising: a head portion comprising a field of cleaning elements; a voltage source; a first set of electrodes disposed on the head portion within the field of cleaning elements and electrically connected to the voltage source, the first set of electrodes comprising a first cathode and a first anode, the first cathode and the first anode having a first electrical potential therebetween when receiving an electric charge from the voltage source; and a second set of electrodes disposed on the head portion and electrically connected to the voltage source, the second set of electrodes comprising a second cathode and a second anode, the second cathode and the second anode having a second electrical potential therebetween when receiving an electric charge from the voltage source, the second set of electrodes being disposed about the first anode; wherein the chemical agent is formed in situ upon contact with an aqueous electrolyte when the first electrical potential is applied wherein the first electrical potential is different from the second electrical potential.
