Cortical activations induced by electrical versus vibrotactile finger stimulation using EEG
NeuroImageSomatosensory evoked potentials (SEPs) recorded with electroencephalography offer insights into cortical responses to tactile stimulation, typically elicited through temporally precise electrical stimulation.

Biomimetic 3D Tactile Sensor System With Neuromorphic Encoding for Fascicle‐Level Feedback
Advanced Intelligent Systems, EarlyView.A 3D biomimetic tactile sensor system converts skin‐like mechanical interactions into neural stimulation‐ready spike patterns. Embedded slow‐ and fast‐adapting sensors distinguish sustained pressure from transient touch, while neuromorphic encoding preserves their temporal signatures.

Temporal integration of vibrotactile patterns [PDF]
Perception & Psychophysics, 1982 Three experiments were conducted to measure the temporal integration of vibrotactile patterns presented to the fingertip. In Experiment 1, letters were divided in half and the time between the onsets of the first half of the letter and second half of the letter, stimulus onset asynchrony (SOA), was varied. The recognizability of the letters declined as

European Eating Disorders Review, EarlyView.ABSTRACT Objective This feasibility randomised controlled trial (RCT) evaluated Purrble, a socially assistive robot for emotion regulation, as a low‐intensity adjunct during waitlist periods in adult eating disorder services. Method Adults waiting for outpatient eating disorder treatment were randomised to four weeks of Purrble use or waitlist‐as‐usual.

Artificial structures for human‐machine interfaces with closed‐loop interaction
FlexMat, EarlyView.Artificial structures bridge sensing and feedback in closed‐loop human‐machine interfaces by providing geometry‐enabled mechanical and functional programmability. This review maps the role of artificial structures in diverse sensing modalities and feedback strategies, and illustrates their integration into closed‐loop interaction systems, highlighting ...

eLife, 2019 The established view is that vibrotactile stimuli evoke two qualitatively distinctive cutaneous sensations, flutter (frequencies < 60 Hz) and vibratory hum (frequencies > 60 Hz), subserved by two distinct receptor types (Meissner’s and Pacinian ...

Journal of Field Robotics, EarlyView.ABSTRACT Wearable haptic interfaces are increasingly important for enhancing human robot collaboration, particularly in decision critical tasks that require intuitive and reliable interaction. Despite advances in wearable systems, existing designs often lack a structured framework that systematically integrates sensing, actuation, control, and user ...

Designing Vibrotactile Scales Based on Human Perception for Encoding Abstract Data
IEEE AccessThis study presents a perceptually grounded method for designing vibrotactile scales. These scales consist of structured sets of calibrated vibrotactile patterns to facilitate reliable differentiation between the values and help users perceive and ...

The Journal of Physiology, EarlyView.Abstract figure legend We delivered trains of brief mechanical pulses to the fingertips of subjects to investigate vibrotactile intensity perception. Some stimuli consisted of bursts of up to four pulses. Simulated responses of the tactile afferent population across the hand revealed that afferents innervating the skin directly under the probe reliably

The Journal of Physiology, EarlyView.Abstract figure legend Patients with fibromyalgia and no‐pain controls completed questionnaire ratings of chronic pain, childhood trauma, anxiety and depression. During the first session a conditioned pain modulation task was administered, with heat pain applied via thermode and cold pain via cold water‐bath.
