Abstract:
    The proposed idea is based on energy shielding of structures from seismic waves, which we aim to achieve through mechanical metamaterials, a highly novel class of materials.
What is the unmet need in society that your idea will fulfill ?
    Pakistan lies in an active seismic zone; however, the practice of seismic isolation is not followed actively in Pakistan's construction industry because the systems that exists are costly, and very complex to design and require special expertise to be implemented. The idea solves these problems.
Who needs it ? How many would benefit ?
   The better adoptability of this system would allow seismic Isolation to be actively implemented in Pakistan. With increase in the use of seismic isolation, structures can be made safe against earthquakes preventing a huge number of deaths in addition to avoiding financial and infrastructure damage.
How will the solution works
    Springs and truss elements work in synergy so that the seismic energy is converted and dissipated as kinetic and potential energies of the spring system. This is achieved by the deforming and restoring movement of the assembly. The assembly is hexagonal in geometry, and the energy from the incident waves is internally dissipated in the lower half, not allowing the waves to pass through to the upper part, hence keeping it stationary along with the structure resting on it as well.
Who are your competitors ? How is your solution different
    Competitors in terms of having a comparative product do not exist however, other devices being used in seismic isolation may serve as potential competitors. These include Lead Rubber Bearings (LRBs), Tuned Mass Dampers (TMDs), Friction Pendulums and Actuator and Control Systems.
