The bistable structure is the thing that makes the permanent shampoo curl hairs. The idea of bi-stable materials is actually, taken from that thing. The bi-stable material means that it has two positions. The bistable material has two structures. When the bistable structure gets the signal it turns from position A to position B. In that movement, the structure transfers kinetic energy to layer B, which makes that material return to its original position. When it gets a counter-signal.
The ultra-tunable bistable structures are tomorrow's materials. The futuristic innovations can create flexible structures that can change their shape at the right moment. The system uses programmable energy barriers that make it possible to change its shape when it faces the right energy load. So when something like a fly touches that surface the structure makes it change its shape. The bistable structures can use in nanotechnology.
"Researchers in China have developed an ultra-tunable bistable structure with programmable energy barriers and trigger forces. The structures can be customized in various geometric configurations, dimensions, materials, and actuation methods for use in robotic applications". (ScitechDaily.com/Shape-Shifting Structures: The Future of Robotic Innovation)
"By reshaping the structure from the metastable state to any intermediate state, the energy barrier decreases, enabling smaller external stimulations to trigger fast snap-through". (ScitechDaily.com/Shape-Shifting Structures: The Future of Robotic Innovation)
"The team demonstrated the tunability of the structure with various prototypes, including a robotic flytrap, grippers, a jumper, a swimmer, a thermal switch, and a sorting system. This work could lead to advances in robotics, biomedical engineering, architecture, and kinetic art. (Abstract fractal art representing shape-shifting structures.)"

These kinds of structures can use for highly advanced loudspeakers. When the right sound impacts that structure it starts to reshape itself. And that allows it to adjust the precise right sound.
And that ability makes this new structure even more flexible than the Chinese researchers who created that material even can imagine. The ultra-tunable material can use to cover aircraft or submarines.
And when that material gets the right signal. It will raise its flaps. So in that case the system just forms small scrapes that make air or water travel easier across the shell of the ship or aircraft. The signal will open those channels and when the system gets a counter-signal it closes those scapes by closing those flaps.
Same way fullerene balls, or nanotubes can improve the hydro-or aerodynamics of the craft or boat. The nanotubes or fullerene nano-balls can cover submarines or any other vehicles. If those molecular-size rolls or balls can rotate freely. That thing can make the surface slippery, and it decreases friction.
