On–Off Switchable Micromotors for Use in Steerable Microvehicles

Advanced Robotics Research, EarlyView.
Electrically controllable micromotors and microvehicles are developed by tuning the diffusion of the fuel. Self‐propelled micromotors using bubble propulsion show great promise for miniaturized devices with multiuse purposes such as cargo delivery and sensing. However, there is currently no method to electrically switch the micromotors on or off. Here,

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

Advanced 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 ...
