  • Publication number: 20070016125
    Abstract: An electroporating apparatus includes an electroporation electrode device that has a substrate, and an electrode unit provided on the substrate. The electrode unit includes a plurality of positive and negative electrode pads each of which has a skin contact surface area with a width ranging from 0.2 mm to 0.8 mm. Each positive electrode pad is spaced apart from the adjacent negative electrode pad by an electrode spacing of ranging from 0.5 mm to 1.5 mm. The positive and negative electrode pads are needleless. With a decrease in electrode spacing and electrode width, painless electroporation can be achieved when electric pulses of 0.2 ms or less and 150 V or less are applied is to a skin at 10 Hz or less.

  • Publication number: 20060004321
    Abstract: A painless drug delivery electrode device includes a substrate having top and bottom sides, and an electrode unit provided on the top side of the substrate and adapted to convey pulse signals to a skin. The electrode unit includes a plurality of positive and negative electrode pads which are adapted to contact the skin and which are arranged in rows. Each of the positive and negative electrode pads has a skin contact surface area smaller than 1 sq. mm. Each of the positive electrode pads is spaced apart from an adjacent one of the negative electrodes by a distance ranging from 0.2-1 mm.
