US 8,620,434 B2 · Method and system for dynamic recalibration of tens stimulation points to compensate for changing electrode conditions with fail-safe and auto-recovery functionality

Abstract

A device and method for applying transcutaneous electrical nerve stimulation via an electrode. The device includes the electrode being arranged for detecting a change of a skin impedance and being configured for switching from a stimulation mode of operation for stimulating the nerve, into a recalibration mode of operation upon detection of the changed skin impedance. The device may include a plurality of electrodes being configured for detecting the change of the skin impedance and being configured for adjusting an electrical current flowing through the skin via the plurality of electrodes.
