Electrospinning apparatus 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 having a first end and a second end opposite the first end;
• and
• a consumable portion coupled to the first end of the durable portion,
• wherein the consumable portion includes:
• an electrode,
• a hollow nozzle configured to output the solution from a nozzle tip thereof, the hollow nozzle defining a first portion of a flow path of the solution to outside the device, and the nozzle tip defines a second portion of the flow path, and
• a housing 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 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 and move radially inward to control the drive mechanism and application of a high voltage to the electrode to create an electric field for application to the solution to electrospin o electrospray the solution from the hollow nozzle toward the deposit surface,
• wherein circuitry is configured to provide the high voltage to the electrode,
• wherein the switch is closer to the second end of the durable portion than the housing of the consumable portion is to the second end of the durable portion,
• wherein the housing of the consumable portion that contains the predetermuied maximum volume of the solution has a proximal end at which the solution is output and a distal end opposite the proximal end, and
• wherein the distal end of the housing is closer to the nozzle tip than the switch is to the nozzle tip.

A method comprising:

• providing a portable, hand-held device for electrospinning or electrospraying toward a deposit surface a predetermined solution formulated for the device;
• and
• using the device to electrospin or electrospray the predetermined solution toward the deposit surface, the device comprising:
• a durable portion having a first end and a second end opposite the first end;
• and
• a consumable portion coupled to the first end of the durable portion,
• wherein the consumable portion includes:
• an electrode,
• a hollow nozzle configured to output the solution from a nozzle tip thereof the hollow nozzle defining a first portion of a flow path of the solution to outside the device, and the nozzle tip defines a second portion of the flow path, and
• a housing 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 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 and move radially inward to control the drive mechanism and application of a high voltage to the 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 electrode,
• wherein the switch is closer to the second end of the durable portion than the housing of the consumable portion is to the second end of the durable portion, and
• wherein no portion of the switch overlaps the consumable portion in a top plan view of the device.
