18 Claims

1. A method of treating restless legs syndrome (RLS), the method comprising:

affixing a patch externally on a dermis of a user adjacent to a targeted nerve of the user, the patch comprising a flexible substrate, a processor directly coupled to the substrate, and electrodes directly coupled to the substrate;

detecting an occurrence of RLS; and

in response to the detecting, activating the patch, the activating comprising generating electrical stimuli via the electrodes that is directed to the targeted nerve, the activating further comprising:

determining a target charge level;

outputting a series of pulses from the electrodes;

for each pulse outputted, measuring a charge value of the pulse and compare the charge value to the target charge level;

if the charge value is greater than the target charge level, reducing a strength level of a subsequent outputted pulse;

if the charge value is less than the target charge level, increasing the strength level of a subsequent outputted pulse; and

repeating the determining, outputting and measuring.
