Electrospinning devices and systems and methods thereof

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 semi-durable portion configured to removably receive therein a consumable portion,
• wherein the semi-durable portion is configured to be removably coupled to the durable portion,
• wherein the durable portion is configured to provide a high voltage to the semi-durable portion and includes:
• a user control interface configured to receive manual input from a user to control a drive mechanism and application of the high voltage to at least one electrode to create an electric field for application to the solution to electrospin or electrospray the solution from a nozzle of the semi-durable portion toward the deposit surface,
• wherein the semi-durable portion is configured to provide the high voltage to the at least one electrode and includes:
• the nozzle, which is configured to output the solution from a nozzle tip thereof, and
• the at least one electrode, which is inside the nozzle,
• wherein the at least one electrode includes:
• a hollow tube, and
• a conductive body portion surrounding the hollow tube such that a portion of the hollow tube extends from a first side of the conductive body portion,
• wherein the conductive body portion forms at least one secondary electrode, and
• wherein a second side of the conductive body opposite the first side corresponds to an outward-facing side of a second planar portion, the second side having one or more projections extending therefrom,
• wherein the device further comprises a high voltage (HV) line to provide the high voltage from the durable portion to the semi-durable portion, the HV line being surrounded by insulation of the semi-durable and/or insulation of the durable portion.
