A novel instrument able to acquire Skin Potential Response (SPR) signals is proposed; SPR is a branch of Electrodermal Activity (EDA) and consists of reading nervous electric pulses that arise when the sympathetic nervous system activates sweat glands as a reaction of an external stressing stimulus.

Abstract
A novel instrument able to acquire Skin Potential Response (SPR) signals is proposed; SPR is a branch of Electrodermal Activity (EDA) and consists of reading nervous electric pulses that arise when the sympathetic nervous system activates sweat glands as a reaction of an external stressing stimulus. Scientific literature shows that EDA is a good methodology to detect workload, increased stress level and many neurological diseases or addictions. In this paper, we present the design and characterization of a wearable, battery operated, wireless device which can acquire SPR data and can be integrated in a wireless sensor network for the AAL. The developed control panel is responsible of receiving the SPR data, plotting them in real time and, on a secondary screen, providing to the patient visual and auditory stimuli; as a further stimuli generator, an adaptive game controlled by the SPR signal has been developed. The synchronous plot of stimuli markers and SPR signal on the same graph can provide a very useful information for the SPR analysis.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
