On–Off Switchable Micromotors for Use in Steerable Microvehicles

open access: yesAdvanced 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,

Mesoporous materials

open access: yes, 2001
Recently, mesoporous metal films containing high surface areas have been produced electrochemically by using lyotropic liquid crystalline phases as templating agents. The main advantage is the versatility of this method, where other materials can be prepared.

Recent Advances in Variable‐Stiffness Robotic Systems Enabled by Phase‐Change Materials

open access: yesAdvanced Robotics Research, EarlyView.
Phase‐change materials (PCMs), such as shape memory alloys, hydrogels, shape memory polymers, liquid crystal elastomers, and low‐melting‐point alloys, are driving advancements in stiffness‐tunable robotic systems across a wide range of applications. This review highlights recent progress in PCM‐enabled robotics, focusing on their underlying mechanisms,
