AI summary

Wearable neuromodulator devices. The devices may include a first electrode and a second electrode on a flexible substrate. A first hydrogel layer may be in electrical communication with the first electrode and a second hydrogel layer may be in electrical communication with the second electrode. A third hydrogel layer may be in electrical communication with the first hydrogel layer. The first hydrogel layer may be separated from the third hydrogel layer by a removable release layer. A circuit interrupt may be removably coupled with control circuitry. The circuit interrupt may be interposed between a battery and the control circuitry so that removing the circuit interrupt powers the control circuitry. The control circuitry may be configured to deliver a first predefined waveform between the first and second electrodes after the circuit interrupt is removed, and a second predefined waveform between the first and second electrodes after the release layer is removed.
