Abstract
An iontophoretic patch for transdermal delivery of biologically active agents includes at least two electrodes in contact with at least two hydrogel reservoirs. At least one of the hydrogel reservoirs carries at least one active agent and, in use of the iontophoretic patch, is disposed on a user's skin and delivers at least one active agent into the skin. The patch includes a control unit to generate a stimulation pattern having stimulation parameters delivered to stimuli locations on the skin. A stimulation unit generates a time sequence of pulses from the stimulation parameters generated by the control unit. The patch further includes a demultiplexing unit configured to perform independent spatio-temporal distribution of the electrical pulses in the time sequence of pulses to at least one electrode; at least one optical sensing system, for continuously measuring an amount of the active agent in the hydrogel reservoir; and a feedback unit.
