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.

JACC: Cardiovascular Interventions, 2019 With explosive growth in the field of transcatheter therapies in recent years, transcatheter valve-in-valve implantation has rapidly emerged as a viable, low-risk alternative to high-risk redo surgical interventions. The authors review the fundamental clinical principles of transcatheter tricuspid valve-in-valve and valve-in-ring implantation as ...

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 ...

A data-driven model for valve stiction [PDF]
, 2003 The presence of nonlinearities, e.g., striction, hysteresis and backlash in a control valve limits the control loop performance. Striction is the most common problem in spring-diaphragm type valves, which are widely used in the process industry.

Engineered Nanotopography to Modulate Growth and Signaling of Neuronal Networks
Advanced Functional Materials, EarlyView.This study examines the interaction between neurons and nanoscale topographies on engineered substrates. Neurons cultured on nanowires, nanopillars and nanoneedles exhibit enhanced neurite outgrowth, form more organized neuronal circuits, and display improved synaptic connectivity, compared to flat substrates.
