One of the fundamental requirements for an artificial hand to successfully grasp and manipulate an object is to be able to distinguish different objects' shapes and, more specifically, the objects' surface curvatures. In this study, we investigate the possibility of enhancing the curvature detection of embedded tactile sensors by proposing a ridged fingertip structure, simulating human fingerpr...

Cued spatial attention modulates functionally relevant alpha rhythms in visual cortices in humans. Here, we present evidence for analogous phenomena in primary somatosensory neocortex (SI). Using magnetoencephalography, we measured changes in the SI mu rhythm containing mu-alpha (7-14 Hz) and mu-beta (15-29 Hz) components. We found that cued attention impacted mu-alpha in the somatopically loca...

Electronic Skin In article number 2109109, Zhuo Li, Hao Wu, and co-workers adopt flexible mechanical metamaterials to enhance the performance of E-skin strain sensors. Based on tactile perception data from sensors, a generic approach for real-time detection unstable robotic grasping is proposed. Accurate detections in demonstrate great promise sensors dexterous manipulation.

Accurate grasping state detection is critical to the dexterous operation of robots. Robots must use multiple modalities perceive external information, similar humans. The direct fusion method visual and tactile sensing may not provide effective visual–tactile features for network target. To address this issue, we present a novel model (i.e., RFCT) an incremental dimensional tensor product detec...

Impaired responses to tactile stimulation are a commonly reported symptom among children with autism spectrum disorder (ASD). Furthermore, impairments in filtering or habituation to tactile input have been described in ASD. This study measured different aspects of tactile processing to investigate atypical touch sensitivity in children with ASD, methodology that has not been previously used in ...

Most human tasks requiring dexterous manipulation of objects are highly dependent on haptic feedback. The word haptics is originally derived from Greek and means related to the sense of touch. Despite a big surge of robots in manufacturing in the last couple of decades, most of them still lack haptic feedback. In this talk, I will speak about two applications of robotic technology that subsumes...

Somatosensory impairments occur in about half of the cases of stroke. These impairments range from primary deficits in tactile detection and the perception of features, to higher order impairments in haptic object recognition and bodily experience. In this paper, we review the influence of active- and self-touch on somatosensory impairments after stroke. Studies have shown that self-touch impro...

The ability to detect unusual events occurring in the environment is essential for survival. Several studies have pointed to the hippocampus as a key brain structure in novelty detection, a claim substantiated by its wide access to sensory information through the entorhinal cortex and also distinct aspects of its intrinsic circuitry. Novelty detection is implemented by an associative match-mism...

UNLABELLED The present experiment tested 60 individuals on a multiple screen, visual target detection task. Using a within-participant design, individuals received no-cue augmentation, an augmenting tactile cue alone, an augmenting auditory cue alone or both of the latter augmentations in combination. Results showed significant and substantive improvements in performance such that successful se...

Although multisensory integration has been an important area of recent research, most studies focused on audiovisual integration. Importantly, however, the combination of audition and touch can guide our behavior as effectively which we studied here using psychophysics and functional magnetic resonance imaging (fMRI). We tested whether task-irrelevant tactile stimuli would enhance auditory dete...
