A shaving aid delivery system for a shaving system includes a razor head having a resilient reservoir for holding a shaving aid and a piezoelectric ceramic disposed adjacent the resilient reservoir. The delivery system also includes a shaving strip disposed within the razor head, an actuator and an ejection port. The shaving strip is oriented to engage the skin of a user during a shaving stroke and the actuator electrically couples to the piezoelectric ceramic such that, upon activation, the actuator causes deformation of the piezoelectric ceramic which, in turn, deforms the resilient reservoir and forces the shaving aid from the reservoir through the ejection port. Alternatively, the actuator may include a shape memory alloy which, upon transformation between states, deforms the reservoir and forces the shaving aid from the reservoir through the ejection port.

1. A shaving aid delivery system for a shaving system, comprising:a razor head having a plurality of reservoirs for holding a shaving aid, each of said reservoirs including a resilient portion; a shaving strip disposed within said razor head and oriented to engage the skin of a user during a shaving stroke, said shaving strip being positioned relative to each of said reservoirs; an ejection port disposed within each of said reservoirs for issuing said shaving aid from said reservoir into contact with said shaving strip upon activation of an actuator; and at least one piezoelectric material disposed adjacent to said resilient portions of said reservoirs, said piezoelectric material being coupled to an electrical source through said actuator such that, upon activation, said actuator causes deformation of said piezoelectric material which, in turn, deforms said resilient portion of said reservoir and forces said shaving aid from said reservoir through said ejection port. 2. A shaving aid delivery system according to claim 1 wherein said shaving aid is selected from the group consisting of: silicone oils, Aloe Vera compounds, medicinal agents, cosmetic agents, essential oils, vitamin oils, sunflower oils, sesame oils, Jojoba oils, Allantoin, sodium pyruvates, polyethylene oxides, non-ionic polyacrylamides, polysaccharides, sodium lauryl sulphates, polystyrene compounds and polypropylene compounds, Dimenthicone, Alcohol Benzoates, Glycerin, Cety Alcohol, and Steryl Alcohol.3. A shaving aid delivery system according to claim 1 wherein one of said plurality of said reservoirs includes a first shaving aid and another of said plurality of said reservoirs includes a second shaving aid, each of said first and second shaving aids is selected from the group consisting of: silicone oils, Aloe Vera compounds, medicinal agents, cosmetic agents, essential oils, vitamin oils, sunflower oils, sesame oils, Jojoba oils, Allantoin, sodium pyruvates, polyethylene oxides, non-ionic polyacrylamides, polysaccharides, sodium lauryl sulphates, polystyrene compounds and polypropylene compounds, Dimenthicone, Alcohol Benzoates, Glycerin, Cety Alcohol, and Steryl Alcohol.4. A shaving aid delivery system according to claim 1 further comprising a plurality of piezoelectric materials, each of said piezoelectric materials being disposed adjacent one of said plurality of reservoirs.5. A shaving aid delivery system according to claim 4 comprising, a plurality of actuators, each of said actuators being electrically coupled to one of said piezoelectric materials.6. A shaving aid delivery system according to claim 5 wherein each of said actuators is selectively and independently activatable to direct shaving aid from each of said corresponding reservoirs into contact with said shaving strip.7. A shaving aid delivery system according to claim 1 further comprising a plurality of shaving strips, each of said strips being disposed adjacent to one of said plurality of reservoirs.8. A method of ejecting shaving aid from a razor head comprising the steps of:providing a razor head having: an electrical source; reservoir for holding a shaving aid, said reservoir including a resilient portion; a piezoelectric material coupled to said electrical source and disposed adjacent said resilient portion of said reservoir; a shaving strip disposed within said razor head and oriented to engage the skin of a user during a shaving stroke; an ejection part for directing said shaving aid from said reservoir into contact with said shaving strip; and selectively activating the electrical source to deform said piezoelectric material which, in turn, deforms said resilient portion of said reservoir to force said shaving aid from said reservoir through said ejection port into contact with said shaving strip. 9. A shaving aid delivery system for a shaving system, comprising:a razor head having a plurality of reservoirs for holding a shaving aid, each of said reservoirs including a resilient portion; a shaving strip disposed within said razor head and oriented to engage the skin of a user during a shaving stroke, said shaving strip being positioned relative to each of said reservoirs; an ejection port disposed within each of said reservoirs for issuing said shaving aid from said reservoir into contact with said shaving strip upon activation of an actuator; and at least one shape memory alloy disposed adjacent to said resilient portions of said reservoirs, said shape memory alloy being temperature sensitive such that, upon a change in temperature, said shape memory alloy deforms which, in turn, deforms said resilient portion of said reservoir and forces said shaving aid from said reservoir through said ejection port. 10. A shaving aid delivery system for a shaving system, comprising:a razor head having at least one reservoir for holding a shaving aid, said reservoir having at least one resilient portion; a deformable element disposed adjacent to said resilient portion of said reservoir, said deformable element including a piezoelectric material and an electrical source; an ejection port for issuing said shaving aid from said reservoir; and an actuator coupled to said deformable element for initiating deformation of said deformable element which, in turn, deforms said resilient portion of said reservoir and forces said shaving aid from said reservoir through said ejection port. 11. A shaving aid delivery system for a shaving system, comprising:a razor head having at least one reservoir for holding a shaving aid, said reservoir having at least one resilient portion; a deformable element disposed adjacent to said resilient portion of said reservoir, said deformable element including a shape memory alloy which is temperature sensitive; an ejection port for issuing said shaving aid from said reservoir; and an actuator coupled to said deformable element for initiating deformation of said deformable element which, in turn, deforms said resilient portion of said reservoir and forces said shaving aid from said reservoir through said ejection port. 12. A shaving aid delivery system for a shaving system comprising:a razor head having at least one reservoir for holding a shaving aid, said reservoir having at least one resilient portion; a deformable element disposed adjacent to said resilient portion of said reservoir; an ejection port for issuing said shaving aid from said reservoir; an actuator coupled to said deformable element for initiating deformation of said deformable element which, in turn, deforms said resilient portion of said reservoir and forces said shaving aid from said reservoir through said ejection port; and a segmented shaving strip disposed within said razor head and oriented to engage the skin of a user during a shaving stroke.
