Ambient Pressure Responsive Shape-Morphing Electromagnetic Components

This work presents the concept of active electromagnetic components whose response is driven by a new class of shape-morphing materials, which dramatically reconfigure their geometry in response to changes in the ambient pressure of their environment. We discuss, and experimentally demonstrate examples of these components including deployable antennas and wireless, battery free ambient pressure sensors. This principle can be used to design soft, deployable components for applications that will experience large pressure gradients, such as satellites, underwater vehicles and pressurized tanks and pipes.
