Measuring the “on-skin” time of a transcutaneous electrical nerve stimulator (TENS) device in order to minimize skin irritation due to excessive uninterrupted wearing of the same

A method for monitoring the on-skin time of a transcutaneous electrical nerve stimulation (TENS) device, said method comprising the steps of:

• creating a profile of a user;
• applying an electrode array to the skin of the user to provide contact between the electrode array and the skin of the user;
• electrically stimulating at least one nerve of the user with an electrical stimulator connected to the electrode array;
• monitoring the electrode array to determine if the electrode array is positioned on the skin of the user and, when the electrode array is positioned on the skin of the user, recording that determination as an on-skin condition, wherein monitoring the electrode array to determine if the electrode array is positioned on the skin of the user includes monitoring the electrode array when electrical stimulation is being delivered to the user and when electrical stimulation is not being delivered to the user;
• calculating a duration of time of the on-skin condition;
• and
• providing the user with feedback of the duration of time of the on-skin condition, wherein the feedback depends upon the profile of the user.
