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.

All‐dielectric circularly polarised loop antenna made of high‐permittivity ceramic/water

IET Microwaves, Antennas & Propagation
A kind of all‐dielectric circularly polarised (CP) loop antenna made of high‐permittivity material is proposed. The leaky‐wave radiation from a high‐permittivity dielectric waveguide is utilised here to support the operation of the proposed antenna.
