Switchable Terahertz Beam Steering with Near‐Perfect Ordinary Transmission

Advanced Photonics Research, EarlyView.
This study introduces a reconfigurable metasurface that enables switchable terahertz beam steering upon actuation by a global temperature change. At room temperature, it achieves a true “OFF” state with nearly 100% transmission, behaving as if the metasurface is not present, thereby not distorting incoming light.

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,
