1. A method for forming a physiological characteristic sensor, the method comprising the steps of:
- immersing a sensor electrode in a platinum electrolytic bath; and
performing an electrodeposition process by sequentially applying a pulsed signal to the sensor electrode and applying a non-pulsed continuous signal to the sensor electrode to form a platinum deposit on the sensor electrode.

Abstract
A physiological characteristic sensor, a method for forming a physiological characteristic sensor, and a method for forming a platinum deposit having a rough surface are presented here. The method for forming a physiological characteristic sensor includes immersing a sensor electrode in a platinum electrolytic bath. Further, the method includes performing an electrodeposition process by sequentially applying a pulsed signal to the sensor electrode and applying a non-pulsed continuous signal to the sensor electrode to form a platinum deposit on the sensor electrode.
