Embodiment Construction

[0052] The detailed description set forth below in conjunction with the accompanying drawings is intended as a description of various configurations, and is not intended to represent the only structure that can practice the concepts described herein. The detailed description includes specific details in order to provide a thorough understanding of various concepts. However, it will be obvious to those skilled in the art that these concepts can be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form to avoid making these concepts unobvious.

[0053] The word "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any embodiment or embodiment described herein as "exemplary" should not be construed as being more preferred or advantageous over other embodiments. Similarly, the term "embodiments" does not require that all embodiments include the discussed feature, advantage, o...

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.

Description

[0001] Cross references to related applications [0002] This patent application claims the right of priority to provisional application No. 61 / 651,955 filed on May 25, 2012 and entitled "METHODS AND DEVICES FOR ACQUIRING ELECTRODERMAL ACTIVITY ON A HANDHELD DEVICE USING STAINLESS STEEL ELECTRODES", which has been assigned To the assignee of this application, it is expressly incorporated herein by reference. Technical field [0003] In summary, aspects of the present disclosure relate to methods and devices for obtaining galvanic skin activity. Background technique [0004] Electrocutaneous activity (EDA) is measured in microsiemens (μS) and is a term that refers to how the skin conducts electricity when an external direct current (DC) or constant voltage is applied. In other words, EDA measures the conductance of an individual's skin, which varies with the moisture content of sweat emanating from sweat glands (all over the body but most densely on the palms and soles). Electrical...
