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.

Study on the preparation and properties of hydrogel electrolytes

Journal of Physics: Conference Series
Abstract Hydrogels are water-rich network polymers. The hydrophilic groups on the polymer molecular chains ensure their swelling property and high water content, and the cross-linked hydrogel network and the intermolecular interactions between the polymer molecular chains generate cohesive forces to prevent further penetration of water ...
