Abstract
A portable, hand-held electrospinning or electrospraying device and system, method, and portions thereof are described. Such device can be for electrospinning or electrospraying a predetermined solution toward a deposit surface. The device can have a durable portion, a semi-durable portion, and a consumable portion. The consumable portion can be received and held by the semi-durable portion, and the semi-durable portion holding the consumable portion can be removably coupled to the durable portion.
Claims20
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,
- 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.
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, and
- wherein part of the consumable portion overlaps the semi-durable portion in a side view of the device.
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
- wherein the coupling of the semi-durable portion to the durable portion includes a combined electrical and mechanical connection including a connection rod extending from an end of the durable portion and into the semi-durable portion, the connection rod having an end thereof coupled to an elastic member.
