Assessment of Smartphone Technology to Measure Electrodermal Activity: A validation study
-

Central Queensland University, Australia
Aim: Measuring electrodermal activity (EDA) both in laboratory settings and in the field usually requires the use of sophisticated and costly recording equipment. The current study sought to examine whether EDA data recorded with a new Smartphone application and associated recording device would produce comparable results to those obtained by traditional laboratory-based equipment.
Methods EDA was simultaneously recorded using the smartphone application, eSense (Mindfield Biosystems Ltd) and ProComp Infiniti (Thought Technology Ltd) while participants (n = 20) completed a number of tasks. After a resting baseline was recorded, participants engaged in a light exercise task, a deep breathing relaxation task, a visual discrimination task, an auditory habituation task, and a complex cognitive processing task.
Results: A fairly strong correlation was found between the data obtained using the eSense smartphone application and data recorded using the ProComp Infiniti recording device, r(19) = .85, p < .000. While the general EDA trace appeared to be comparable between the two devices, the main factor contributing to the lack of a strong correlation between the two pieces of equipment appeared to be a slight time lag in the eSense recording application.
Conclusions: The results of the current study showed reasonable success of the eSense smartphone application to be used in research settings. Further development of the application and equipment could greatly benefit EDA research by providing a low-cost and portable way of measuring EDA either in a laboratory or in the field.
