Liquid Crystalline Elastomers in Soft Robotics: Assessing Promise and Limitations

open access: yesAdvanced Robotics Research, EarlyView.
Liquid crystalline elastomers (LCEs) are programmable soft materials that undergo large, anisotropic deformation in response to external stimuli. Their molecular alignment encodes directional actuation in a monolithic structure, making them long‐standing candidates for soft robotic systems.

3D‐Printed Macroporous Resin Anode in Microbial Fuel Cell‐Based Biosensors for Efficient Biodegradable Organic Carbon Monitoring

open access: yesAdvanced Sensor Research, EarlyView.
This study presents a 3D‐printed gyroid resin anode for microbial fuel cell biosensors. Compared with carbon felt, it enables either a broader dynamic range or higher sensitivity, depending on the operation mode. By improving real‐time monitoring of organic load, these biosensors support more efficient process control and contribute to the goal of ...
