Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIA
Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 13:
14. A system comprising:
a stimulator comprising an array of independently addressable electrodes configured to be positioned on a patient's skin, each electrode of the array of electrodes is configured for transcutaneous stimulation, wherein the array of independently addressable electrodes comprises:
a plurality of conical spikes each having an electrically insulated portion and a non-insulated tip, and
wherein the non-insulated tip has a shape and height configured to penetrate the patient's skin to bypass one or more of or sweat gland of the patient's skin;

at least one return electrode; and
a controller comprising:
a non-transitory memory storing instructions; and
a processor configured to access the non-transitory memory and to execute the instructions to at least:
deliver an electrical waveform with a set of stimulation parameters to one or more independently addressable electrodes in the array of electrodes; and
deliver another electrical waveform with another set of stimulation parameters to one or more other independently addressable electrodes in the array of electrodes,
wherein the stimulator is configured to emit a shaped and focused electrical field for stimulation of a target tissue based on the electrical waveform and the other electrical waveform.
