1. A device, comprising:
- an array of stainless steel electrodes;
a polarity switching module coupled to the array of stainless steel electrodes for switching polarity of electrodes in the array of stainless steel electrodes;
a memory device; and
at least one processor coupled to the array of stainless steel electrodes and the memory device, the at least one processor configured to;
determine a number of adjacent electrode pairs in the array of stainless steel electrodes contacted to scale a skin conductance response threshold;
fuse all negative electrodes together and all positive electrodes together in the array of stainless steel electrodes upon activation of the electrodes in the array of stainless steel electrodes; and
measure a single overall skin conductance response to capture a total electrode activity measurement.

Abstract
Handheld devices using an array of stainless steel electrodes located on an edge and/or back of the handheld devices for acquiring electrodermal activity are provided. The stainless steel electrode array may allow for the skin conductance level (SCL) or skin conductance response (SCR) on an individual to be measured and collected. The skin conductance signal may be related to sympathetic nervous system activity which is a major component of human emotion, known as arousal, or emotional intensity such as anxiety, stress, fear, or excited, etc.
