Recently, researchers have developed a new material inspired by the squid that has the potential to revolutionize the way we think about self-propelling and self-sensing materials. This material, which is made of a soft, flexible material, has the ability to switch between a “shield” mode and an “open” mode. In its shield mode, this material is capable of providing protection for the material it is covering, while in its open mode, it can act as a barrier to block out external stimuli. This switchable shield has the potential to be used in a variety of applications, from soft robotics to sensing and actuation devices.
