felt that the corrosion on the artificial materials resembled the connection<br />

between the artificial human and nature.<br />

used aluminum (+) and<br />

stainless steel(-).<br />

I experimented with the distance between the positive and negative<br />

poles (the aluminum and the stainless steel) in the salt/baking powder<br />

water. I also applied many different power supplies, from 3V to 6V.<br />

Higher voltage/current produced more gases (oxygen and hydrogen),<br />

created more oxidation and heat – it is almost like a short circuit. For this<br />

project, I used 5V DC and 350 milliamps power supplies and it was fine<br />

for a week [based on personal communication with Eric Graham (Center<br />

for Embedded Networked Sensing)].<br />
