- When exposed to electromagnetic waves in the 4 to 16 GHz range, the OMS demonstrates a resonance frequency shift from 10.24 GHz to 10.144 GHz, resulting in a noticeable change in absorption amplitude.
- The device can detect curvature changes ranging from 0 to 0.327 mm, achieving a maximum sensitivity of 0.918/mm and showing potential for applications in bionic skin, smart robotics, and more due to its wide sensing capabilities.
Article Abstract
In this paper, a liquid crystal (LC) tunable origami metastructure (OMS) designed for curvature sensing on cylindrical surfaces to measure their curvature is introduced. The LC employed is K15 (5CB) and the applicable band is 0.36∼23 GHz. When excited by electromagnetic waves (EMWs) within the 4∼16 GHz, the resonance frequency of the OMS shifts from 10.24 GHz to 10.144 GHz, corresponding to a change in absorption amplitude ranging from 0.773 to 0.920. In terms of curvature sensing, the detectable range of curvature spans from 0 to 0.327 mm. The maximum sensitivity (S) achieved for curvature measurement reaches 0.918/mm, accompanied by a quality factor (Q-factor) of 25.88. The proposed OMS embodies numerous excellent traits, including wide-range sensing capabilities and heightened S, promising for applications in bionic skin, smart robotics, and related fields.
