Abstract
A device for delivery of TENS current, attachable to a handheld skin treatment device with a mechanical motion source, comprises a housing for mounting on the handheld skin treatment device, with a conductive skin contact head with first and second electrodes for receiving a TENS signal as a voltage established between the electrodes and a connector mounted in or on the housing and configured to interface with the mechanical motion source to receive the motion of the motion source. The device has an energy converter in the housing to convert the motion into electrical current, a power control circuit for receiving the electrical current and converting it into at least one power supply output voltage; and a signal generation circuit connected to the at least one the power supply output voltage for producing as an output a TENS signal for delivery to skin.
