Patent ID: 8888249

Claim:
An apparatus for jetting a droplet using a nanotip a first surface of a printable matter, comprising; a main body including; a cantilever having a nanoplate and a nanotip provided under a lower surface of a first end of the nanoplate; a horizontal open channel extending from a chamber, formed in a second end of the nanoplate, to the first end of the nanoplate along an upper surface of the nanoplate so that fluid contained in the chamber is moved to the first end of the nanoplate through the horizontal open channel; a vertical open channel formed in one surface of the nanotip such that a first end thereof communicates with the horizontal open channel and a second end thereof extends to a pointed end of the nanotip so that the fluid that is moved to the first end of the nanoplate is moved to the pointed end of the nanotip through the vertical open channel; and a first electrode provided on at least one predetermined portion to make electrical contact with the fluid; a second electrode provided between the pointed end of the nanotip and the printable matter, the second electrode having therein a through hole, through which a droplet of the fluid is jetted from the pointed end onto the first surface of the printable matter; a power supply to supply a voltage to be applied between the first electrode and the second electrode; and a control unit to control the power supply.
