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 ...

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

Vibrotactile sensitivity and the frequency response of the Pacinian corpuscle [PDF]
Psychonomic Science, 1966 Threshold responses to vibratory stimuli are compared for psychophysical and electrophysiological experiments. There is a striking similarity between the two sets of data. The hypothesis that a duplex mechanism for taction is supported and there is compelling evidence that the Pacinian corpuscle is the neural transducer of vibratory stimuli.

A Simple and Compact MR-Compatible Electromagnetic Vibrotactile Stimulator
Frontiers in Neuroscience, 2020 We have developed a low-cost electromagnetic vibrotactile stimulator that uses the magnetic field of an MR scanner as a permanent magnet to power a vibrating motor.

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.

Effect of stimulus frequency on subjective vibrotactile magnitude functions [PDF]
Perception & Psychophysics, 1975 Subjective magnitude functions were determined by the method of magnitude estimation at 60 and 250 Hz at the fingertip and thenar eminence, both with and without a rigid surface surrounding the contactor. When the surround was in place, the slopes of the curves were independent of stimulus frequency.

Micromachines, 2017 The integration of polymeric actuators in haptic displays is widespread nowadays, especially in virtual reality and rehabilitation applications. However, we are still far from optimizing the transducer ability in conveying sensory information.

The Journal of Physiology, EarlyView.Abstract figure legend The study investigated the modulatory effects of affective touch on temporal summation of second pain (TSSP) in 32 romantic couples (N = 64). The design included a dyadic session (partner's CT‐optimal stroking vs. static touch) and an individual session (robotic CT‐touch vs. vibration control).
