Shimmer3 GSR+ Kit 
Discontinued
The Shimmer3 GSR+ (Galvanic Skin Response) monitors skin conductivity between two reusable electrodes attached to two fingers of one hand. Caused by a stimulus the sweat glands become more active, increasing moisture on the skin and allowing the current to flow more readily by changing the balance of positive and negative ions in the secreted fluid (increasing skin conductance).
The Shimmer3 GSR+ unit can also provide a photoplethysmogram (PPG) signal from a finger, ear-lobe, or other location on the body when adding an Optical Pulse probe.
Shimmer is a widely used and trusted product with a long publication history. Find white papers, research papers and more here: https://shimmersensing.com/support/publications/
Why Chose Shimmer3 GSR+?
Reliable System
- Validated for use in biomedical-oriented research applications
- Four digitally controlled measurement ranges which developers use to ensure accurate measurements
- Gain selection can be hard-coded or manually selected
- Phasic conductance can be observed with respect to baseline level of skin conductance
Real-time Data Collection, Display, and Storage
- Provides pre-amplification of GSR signal, converts to digital format, and can stream directly to a host device without the need for an intermediate receiving unit.
- Provides real-time physiological data collection and streaming to a host PC for real-time display and storage
- Real-time LabVIEW drivers and support library for application specific analysis and software interface development
Lightweight, Wearable Unit
- Designed to be wearable, the Shimmer GSR addresses challenges of mobility and provides a high-quality, scientifically reliable data as either a wireless transmitter or an autonomous data-logger
- Free from wired constraints, the Shimmer GSR provides a comfortable and distress free solution for athletes, children, elderly and patients with a disability
- The small size and lightweight (28g) design allows the unit to be worn on any body segment for full range of motion during all types of tasks or exercises, without effecting their movement, techniques, or motor pattern
Adaptability (Wired vs. Wireless)
- Offers greater ergonomic value than larger wired units
- Easily combine GSR data with Shimmer’s integrated accelerometer for greater contextual information
- Easily combine GSR data with the full range of Shimmer Biophysical, Kinematic and Ambient sensor modules
Leverages Shimmer3 Functionality
- MSP430 microcontroller (24MHz, MSP430 CPU)
- Bluetooth Radio – RN-42
- Integrated 8GB micro SD card
- 450mAh rechargeable Li-ion battery
- Low profile & stylish wearable enclosure
- Highly configurable to user/developer’s specific needs

Cognitive Behavioral Therapy Reduces Symptom Severity and Normalizes Neurophysiological and Attentional Reactivity in Anorexia Nervosa: A Randomized Controlled Trial
Beykoz University + 2 more
Background: Anorexia nervosa (AN) is a severe psychiatric disorder marked by restrictive eating, distorted body image, and high relapse rates. While cognitive-behavioral therapy (CBT) is a widely used treatment, its mechanisms of action in AN remain incompletely understood, particularly beyond self-reported symptom change. This study investigated the effects of a 12-week CBT intervention on both […]

How do attention and emotion drive donations in charitable crowdfunding? An empirical study of users’ cognitive and physiological responses to image content
Copenhagen Business School
Abstract: This study investigates the attentional and emotional impact of different image types in medical crowdfunding campaigns, and how these images impact donations. Building on signaling theory and evolutionary explanations for the drivers of altruism, we hypothesized that donors will be more likely to support campaigns with images that depict illness than campaigns with images […]

User Interaction with Digital Twins for Driving: How Comparable Are Simulated and Real Trajectories?
University of Applied Sciences Hof + 4 more
Abstract This paper investigates the physiological responses of individuals driving both on a real route and within a vehicle simulator designed as a digital twin of that route. The analysis of observed data patterns in stress response bio signals provides sufficient evidence of similarity to validating the driving simulation digital twin as a reliable replacement […]

Decoding consumer responses to anthropomorphic products using electroencephalography, skin conductance, and eye-tracking
Hubei University
Anthropomorphic product design is often assumed to increase consumer engagement, but its neural mechanisms and boundary conditions remain underexplored. This study employed a multimodal neuroscientific approach—electroencephalography (EEG), galvanic skin response (GSR), and eye-tracking—to examine how anthropomorphized versus non-anthropomorphized products influence consumer responses. Forty-four young adults viewed AI-generated images of beverages, backpacks, and smartphones. While anthropomorphic […]

THE HIDDEN DIMENSION OF CONSUMER REACTIONS: NEUROMARKETING EVIDENCE AND ADVERTISING LITERACY
University of Ss. Cyril and Methodius in Trnava
Abstract:Advertising literacy has long been studied primarily through explicit methods such as questionnaires and interviews, which capture respondents’ self-reported knowledge and attitudes. However, these approaches face serious limitations – they are prone to biases such as social desirability and often fail to capture implicit processes involved in advertising perception that occur outside conscious reflection. Our […]

Disrupting the browsing experience: impact of sponsored social media content on affective flow without driving engagement
Ruhr West University of Applied Sciences + 2 more
Introduction: Understanding how emotional experiences shape consumer behavior in digital environments is a central issue in decision-making neuroscience. While social media feeds are saturated with sponsored content, little is known about how such content modulates affective rhythms and influences engagement.

Blending in or standing out? The disclosure dilemma of ad cues of social media native advertising
Ruhr West University of Applied Sciences + 2 more
Introduction: As social media platforms increasingly rely on native advertising embedded within user feeds, an open question is whether sponsored posts garner comparable, greater, or reduced attention relative to surrounding non-sponsored content. Subtle cues (e.g., disclosures, call-to-action (CTA) buttons) may alert users to the commercial nature of these posts or remain unnoticed in rapid-scroll environments. In […]
