The stylus may include a stem having a grip region and an end having a tip. This stylus may include a conductive path between the grip region and the tip having an electrical conductivity that is greater than a predefined amount. During use, a user may grasp or hold the grip region of the stylus. Then, while maintaining contact with the stylus, the user may touch or contact a surface of, e.g., a touch-sensitive display at a contact point using the tip. The stylus may form a conductive path between the user's fingers and the surface. This conductive path may allow the user to transfer or redistribute electric charge to or in the touch-sensitive display, so that a location of the contact point may be determined by the touch-sensitive display while protecting the user from pathogens on or associated with the surface. ## Claims ### Claim 1 A stylus, comprising: a stem having a grip region and an end having a tip, wherein the stylus comprises a conductive path between the grip region and the tip, wherein the tip has a surface resistance less than 102Ω and the stem has a surface resistance less than 104Ω, or a conductive path between the grip region and the tip having an electrical conductivity greater than 10−13 S/m, and wherein the stylus is disposable. ### Claim 2 (depends on 1) The stylus of claim 1, wherein the stylus is configured for use with a touch-sensitive display based on a capacitive detection technique. ### Claim 3 (depends on 1) The stylus of claim 1, wherein the stylus is configured for use with a physical button. ### Claim 4 (depends on 1) The stylus of claim 1, wherein the stylus is configured for use with a human-interface device. ### Claim 5 (depends on 1) The stylus of claim 1, wherein the tip has a Shore hardness between Shore 00-0 and Shore D-0. ### Claim 6 (depends on 1) The stylus of claim 1, wherein the stem has a Shore hardness between Shore 00-90 and Shore D-100. ### Claim 7 (depends on 1) The stylus of claim 1, wherein the stylus comprises a material including conductive fibers that provide the conductive path. ### Claim 8 (depends on 1) The stylus of claim 1, wherein at least a portion of the stylus includes a conductive coating. ### Claim 9 A package, comprising: a housing surrounding a stylus, wherein the stylus comprises: a stem having a grip region and an end having a tip, wherein the stylus comprises a conductive path between the grip region and the tip, wherein the tip has a surface resistance less than 102Ω and the stem has a surface resistance less than 104Ω, or a conductive path between the grip region and the tip having an electrical conductivity greater than 10−13 S/m, and wherein the stylus is disposable. ### Claim 10 (depends on 9) The package of claim 9, wherein the housing comprises a hook or a receptacle configured to remateably couple to a hook. ### Claim 11 (depends on 9) The package of claim 9, wherein the package comprises multiple instances of the stylus. ### Claim 12 (depends on 9) The package of claim 9, wherein the stylus is configured for use with a touch-sensitive display based on a capacitive detection technique. ### Claim 13 (depends on 9) The package of claim 9, wherein the tip has a Shore hardness between Shore 00-0 and Shore D-0; and wherein the stem has a Shore hardness between Shore 00-90 and Shore D-100. ### Claim 14 (depends on 9) The package of claim 9, wherein the stylus comprises a material including conductive fibers that provide the conductive path or at least a portion of the stylus includes a conductive coating. ### Claim 15 A method for providing instructions, comprising: providing a stylus, wherein the stylus comprises: a stem having a grip region and an end having a tip, wherein the stylus comprises a conductive path between the grip region and the tip, wherein the tip has a surface resistance less than 102Ω and the stem has a surface resistance less than 104Ω, or a conductive path between the grip region and the tip having an electrical conductivity greater than 10−13 S/m, and wherein the stylus is disposable; and providing or displaying instructions for use of the stylus, wherein the instructions indicate that a user grasp the stylus at the grip region and touch the tip to a surface of a touch-sensitive display. ### Claim 16 (depends on 15) The method of claim 15, wherein the touch-sensitive display is based on a capacitive detection technique. ### Claim 17 (depends on 15) The method of claim 15, wherein the tip has a Shore hardness between Shore 00-0 and Shore D-0; and wherein the stem has a Shore hardness between Shore 00-90 and Shore D-100. ### Claim 18 (depends on 15) The method of claim 15, wherein the stylus comprises a material including conductive fibers that provide the conductive path or at least a portion of the stylus includes a conductive coating. ### Claim 19 (depends on 15) The method of claim 15, wherein the instructions indicate that the stylus is for use with the touch-sensitive display. ### Claim 20 (depends on 15) The method of claim 15, wherein the instructions indicate that the stylus is for use with a physical button.
