1. A wearable neurostimulation device for transcutaneously stimulating one or more peripheral nerves of a user, the device comprising:
circuitry for generating electric stimulation signals;
a plurality of electrodes configured to emit the electric stimulation signals; and
one or more hardware processors configured to:
measure a plurality of electromagnetic characteristics across at least two of the plurality of electrodes,
wherein the at least two of the plurality of electrodes comprises a first electrode and a second electrode,
wherein the plurality of electromagnetic characteristics comprises a first electromagnetic characteristic of the first electrode, and
wherein the plurality of electromagnetic characteristics comprises a second electromagnetic characteristic of the second electrode;
determine a plurality of connection quality indicators based on the first electromagnetic characteristic and the second electromagnetic characteristic, said connection quality indicators corresponding to a degree of connection between the first electrode and the second electrode with skin of the user;
maintain one or more counters for the plurality of connection quality indicators over a time window based on repeated measurements of the plurality of electromagnetic characteristics within the time window;
wherein maintaining one or more counters for the plurality of connection quality indicators comprises determining if at least one of the one or more counters crosses a threshold within the time window; and
change an operating characteristic of the wearable neurostimulation device if at least one of the one or more counters has crossed the threshold within the time window;
wherein the one or more hardware processors are capable of determining the plurality of connection quality indicators based on the plurality of electromagnetic characteristics.
