Multistable Lattices

enabling adaptable and deployable structures

What’s This About?

Materials with multiple stable states exhibit intriguing dynamic behaviors such as phase transitions, dislocation propagation, and transition waves. While these effects have been well-studied in ferroelectrics, ferromagnets, and shape memory alloys, recent advancements in mechanical metamaterials have enabled the development of macroscopic multistable systems with unprecedented tunability. By precisely engineering energy landscapes, we can achieve controlled phase transitions, enabling the design of adaptive, deployable, and load-bearing structures with tailored mechanical properties.


Why Does It Matter?

Multistable lattices provide exceptional tunability, making them ideal for reconfigurable systems that dynamically respond to external stimuli. This capability is critical for:

  • Soft Robotics – Enabling flexible, shape-changing actuators with programmable motion.
  • Energy Absorption – Developing impact-resistant materials that efficiently dissipate energy.
  • Deployable & Load-Bearing Structures – Creating mechanically robust yet adaptable architectures for aerospace, civil engineering, and infrastructure applications.
  • Sound & Vibration Control – Engineering materials that manipulate wave propagation through stable and transitional states.

By advancing our understanding of multistable lattices, we aim to develop next-generation adaptive materials that dynamically adjust to their environment while maintaining structural integrity.


What We’re Working on Right Now

Our research focuses on tunable multistable metamaterials with controllable phase transitions. Current projects include:
