摘要： A metamaterial force sensor, the sensor comprising: one or more metamaterial modules, each module comprising a plurality of mechanical unit cells operatively interconnected to allow force transmission therethrough; a transducer operatively coupled to the or each module, the transducer being configured to output a signal corresponding to a displacement of the or each module in response to a force transmission, wherein each of the mechanical unit cells provides a predetermined range of displacement, based on preconfigured structural parameters of said unit cell, in response to force transmissions, and wherein at least two of the mechanical unit cells of the or each module are configured with different predetermined ranges of displacement in response to force transmissions resulting in multiple sensitivity regimes.
