A dual purpose wearable patch includes a stretchable and permeable substrate, a sensing unit mounted in the stretchable and permeable substrate, wherein the sensing unit can conduct a measurement of a user to produce a measurement signal, one or more electrodes respectively attached to the stretchable and permeable substrate, a circuit substrate on the stretchable and permeable substrate, wherein the circuit substrate includes a circuit electrically connected with the one or more electrodes and the sensing unit, and a semiconductor chip mounted on the circuit substrate and in connection with the circuit. The semiconductor chip can receive the measurement signal from the sensing unit and can produce a treatment control signal to control the one or more electrodes to apply a voltage across the users body.
