| Abstract Scope |
Mechanosensing is a key property for adaptable and smart structures. To translate this functionality to large and stiff structures, filtered sensing is required to decrease the amount of data sensed locally and select the relevant level of input stress. Filtered sensing using mechanical displacement is one strategy used in Nature to cope with large sets of stimuli. Here, we fabricate bistable elements that can passively filter mechanical inputs, translate them into electrical signals, and be reset using an external magnetic field. These multiple functionalities are achieved using hierarchically structured composites that can be arranged in large-area arrays and processed using additive manufacturing approaches. The filtering capability and fast passive response of the mechanosensors are experimentally demonstrated using simple electrical circuits and magnets and show potential for load-bearing structures that are able to sense, compute, communicate, and autonomously adapt. |
