Advanced Science, EarlyView.General schematic of the approach. Abstract Conventional Silver/Silver Chloride (Ag/AgCl) electrodes remain the clinical standard for electrophysiological monitoring but are hindered by poor skin conformity, mechanical rigidity, and signal degradation, particularly under motion or sweat.

A Wireless, Battery‐Free Artificial Throat Patch with Deep Learning for Emotional Speech Recognition
Advanced Science, EarlyView.In this work, Xu and co‐workers develop a wireless, battery‐free artificial throat patch system (ATPS) consisting of a carbon nanotube‐based thin‐film strain sensor and a miniaturized flexible printed circuit board, to enable real‐time sensing of throat signals.

A Soft Robotic Model for Simulating Heart Valve Disease and Cardiac Interventions
Advanced Science, EarlyView.This paper introduces a fully synthetic fabrication methodology for a soft robotic, in‐vitro model of the left‐heart, complete with a functioning mitral valve apparatus. With a view towards patient‐specific modeling, we demonstrate physiological flow and pressure waveforms, tunable mitral valve function with clinical imaging compatibility, and its use ...

Biological Motion Alters Coherent Motion Perception
Perception, 2008When a movie presents a person walking, the background appears to move in the direction opposite to the person's gait. This study verified this backscroll illusion by presenting a point-light walker against a background of a random-dot cinematogram (RDC).

Monocular motion sensing, binocular motion perception
Vision Research, 1989The two-process account of motion perception and its binocular organization were addressed in experiments on apparent movement (AM) with three types of grating: sinusoidal; random bar width; and square-wave with missing fundamental (MF). Monocular MF gratings sampled four times per cycle of drift always appeared to move backwards. Here AM was unrelated

Abstract The ability to detect motion is one of the most important properties of our visual system and the visual systems of nearly every other species. Motion perception is not just important for detecting the movement of objects—both for catching prey and for avoiding predators—but it is also important for providing information about ...

Scientific American, 1975
In this article the author uses projective relations as the theoretical foundation of his investigations of visual space and motion. Several laboratory experiments involving perceptual vector analysis and its geometric basis are described. In most of the experiments the visual stimuli consisted of computer-controlled patterns displayed on a ...

Annual Review of Psychology, 2007
Abstract Humans, being highly social creatures, rely heavily on the ability to perceive what others are doing and to infer from gestures and expressions what others may be intending to do. These perceptual skills are easily mastered by most, but not all, people, in large part because human action readily communicates intentions and feelings. In recent

Perception of Biological Motion
Perception, 1997Boundary conditions for perception of biological motion were explored with the use of computer-generated point-light animation sequences. Perception of this unique form of structure from motion is immune to variations in dot contrast polarity, dot disparity, and spatial-frequency filtering.

Reversed rotary motion perception
Journal of the Optical Society of America A, 1991A stroboscopically presented revolving annulus composed of dots is used to elicit rotary motion perception. Observers judge the direction of rotary motion. We find sharp and gradual transitions in the probability for reversed motion perception as a function of the angle of rotation between successive frames.
