1. A portable, hand-held device for electrospinning or electrospraying toward a deposit surface a predetermined solution formulated for the device, the device comprising:
a durable portion; and
a consumable portion coupled to the durable portion,
wherein the consumable portion includes:
a hollow nozzle configured to output the solution from a nozzle tip thereof, an inner peripheral surface of the hollow nozzle having a hollow electrode defining a first portion of a flow path of the solution to outside the device so that the hollow electrode and the solution are in direct contact with each other, and the nozzle tip defining a second portion of the flow path, and
a housing including a solution container configured to contain a predetermined maximum volume of the solution, and output the solution to the hollow nozzle, wherein the durable portion includes:
a drive mechanism configured to cause the solution from the housing to be output to the hollow nozzle, and
a user control interface including a switch configured to receive manual input from a user in the form of a pressing operation to control the drive mechanism and application of a high voltage to the hollow electrode to create an electric field for application to the solution to electrospin or electrospray the solution from the hollow nozzle toward the deposit surface,
wherein circuitry is configured to provide the high voltage to the hollow electrode, and
wherein a first end of the hollow electrode is disposed in the hollow nozzle and a second end of the hollow electrode is disposed in the solution container.
