“…However, the methods outlined in the literature are still preliminary. Non-invasive methods, like functional magnetic resonance imaging (fMRI) and electroencephalography (EEG), were adopted for direct capturing of the neural responses in the nervous system [ 2 , 8 , 9 ]. For example, fMRI has been utilized to identify the neural pathways related to the fabric stimuli at different sites of the forearm, during which 13 healthy participants were recruited to test four fabrics using a robotic caressing device [ 9 ].…”

“…Due to the sensory adaptation, the transient sensory neural responses will attenuate quickly during tonic tactile stimulation (in milliseconds) [ 10 , 11 ]. Hoefer et al [ 8 ] employed the event-related potential (ERP) in the time domain captured by EEG during fabric stimulation on the ventral side of the forearm to discriminate different fabric samples (n = 3). They observed non-coincidently different ERP amplitudes in 24 test subjects by varying fabric stimuli on the forearm.…”

The precise evaluation of sensory perceptions during fabric-skin interactions is still poorly understood in neuroscience. This study aims to investigate the cortical sensory response to fabric stimuli with different textiles by Electroencephalographic (EEG) spectral intensities, and evaluate the relationships between EEG frequency bands, traditional subjective questionnaires, and the materials’ physical properties. Twelve healthy adult participants were recruited to test three fabrics with different textile compositions of 1) cotton, 2) nylon, and 3) polyester and wool. The physical properties of the fabrics were quantitatively evaluated by a Fabric Touch Tester (FTT). Subjects were invited to rate the sensory perception of the fabric samples via a subjective questionnaire and objective EEG recording. Significant differences in the EEG relative spectral power of Theta and Gamma bands were acquired in response to the different fabric stimuli ( P <0.05). The Theta and Gamma powers demonstrated a significant correlation with the most of the subjective sensations evaluated by questionnaire and the fabrics’ physical properties by FTT ( P <0.05). The EEG spectral analysis could feasibly be used for the discrimination of fabric stimuli with different textile compositions and further indicates sensory perceptions during fabric stimulation. This finding may provide evidence for further exploratory research of sensory perceptions via EEG spectral analysis, which could be applied to the study of brain generators of skin tactility in future prostheses and the automatic detection of sensory perception in industries.

“…A normal person has five senses including smell, sight, hearing, touch, and taste. Sense‐related information is transmitted to the brain, and subsequently the specific emotion is decided . All the information gathered by the five senses is input to the amygdala; the input data are significant for shaping the behavior by emotion.…”

“…EEG is a universally used device for brainwave measurements and can verify the brain activity using numerous brainwaves. The measurement is performed based on the International 10-20 system, and the wavelengths are classified into delta (0.5-4 Hz), theta (4-8 Hz), alpha (8)(9)(10)(11)(12)(13), beta (13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30), and gamma . Through the association between brainwave and fragrance, the effects of fragrance on mood and preference can be verified.…”

Background The stabilizing effect of lavender and the arousal effect of peppermint essential oils are acknowledged and used widely in aromatherapy and the cosmetics industry. However, no evaluation method confirms the effects of essential oils through quantitative and objective electroencephalogram (EEG) results; instead, only a psychological and subjective method exists. Therefore, this study aims to create a new emotional cosmetic evaluation paradigm using EEG values. Moreover, it enables quantitative interpretation of the results in addition to the subjective survey outcomes. Methods For this study, 12 healthy female Korean participants were recruited and three fragrances were used. The EEG results were collected for 3 minutes (1 minute each before, during, and after inhalation of every fragrance). Results The quantitative EEG outcomes indicate changes in the participant's brainwaves before and after inhalation. Significant changes in the EEG were observed. Based on the results, the effects of fragrances were confirmed to be stabilizing for lavender, and arousing for peppermint and coffee aroma. Furthermore, the subjective questionnaire results indicate similar tendency as that of the quantitative EEG results. Conclusion In addition to psychological and subjective assessments, our emotional evaluation method can verify the cosmetic fragrance effects through quantitative and objective results.
