An Edible Chitosan‐Based Acoustic Sensor for Sound‐Responsive Actuation in Edible Robots

Advanced Functional Materials, EarlyView.
This study introduces an edible acoustic sensor for robotic food and edible robotics. Built from a chitosan piezoelectric film between gold electrodes, the sensor enables acoustic communication through ON/OFF keying. Integrated into an edible robot with pneumatically actuated arms and neck, it responds to high‐frequency tones.

Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite

Advanced Functional Materials, EarlyView.
The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.

Light‐Induced Field‐Tunneling Synapses in Solution‐Processed Van Der Waals Heterostructures for Scalable, Retina‐Inspired Optical Sensing

Advanced Functional Materials, EarlyView.
A scalable, solution‐processed WSe2/ZrO2‐x van der Waals heterostructure realizes a light‐induced field‐tunneling synapse (LIFTS) that activates exclusively under bright illumination, emulating the photopic adaptation of the human retina at the device level.

Dynamically Actuated Reconfigurable Topographical Surface Enables Active Control of Implant‐Associated Infections

Advanced Functional Materials, EarlyView.
A dynamically actuated reconfigurable topographical surface (DARTS) integrates contact‐mediated bactericidal nanotopography with programmable mechanical actuation to actively disrupt bacterial biofilms. Dynamic surface reconfiguration enhances bacterial killing and suppresses implant‐associated infections in vivo, providing a new strategy for active ...

Predictive Smooth Pursuit Eye Movements

Annual Review of Vision Science, 2019
Smooth pursuit eye movements maintain the line of sight on smoothly moving targets. Although often studied as a response to sensory motion, pursuit anticipates changes in motion trajectories, thus reducing harmful consequences due to sensorimotor processing delays.

Prediction in Smooth Pursuit

Acta Oto-Laryngologica, 1987
A quantitative analysis of prediction in smooth pursuit was made in 23 normal subjects. The target wave (random sinusoidal wave), which contains a predictive portion and a nonpredictive portion, was developed by the authors, using a microcomputer. Five parameters were established quantitatively after microcomputer A/D conversion of the eye movements ...

Smooth Pursuit of Nonvisual Motion

Journal of Neurophysiology, 2006
Unlike saccades, smooth pursuit eye movements (SPEMs) are not under voluntary control and their initiation generally requires a moving visual target. However, there are various reports of limited smooth pursuit of the motion of a subject’s own finger in total darkness (pursuit based on proprioceptive feedback) and to the combination of proprioception ...

Neurology of saccades and smooth pursuit

Current Opinion in Neurology, 1999
During the period covered by this review a number of papers have been published on saccade and smooth pursuit research, conducted experimentally in monkeys and clinically in humans. In monkeys, using mainly electrophysiological methods, the roles of the frontal eye field, parietal eye field and supplementary eye field at the cortical level, and those ...
