Application of Negative Poisson’s Ratio Honeycomb Structure in Acceleration Measurements

Abstract

The measurement of acceleration plays an essential role in evaluating the state of mechanical equipment. The acceleration transducers are the most widely used devices for measuring vibration, motion, and shock. This paper proposes a novel method of acceleration measurement based on auxetic honeycomb structure. By using this method, the change in the auxetic honeycomb structure’s transmittance caused by elastic deformation under acceleration can be converted into a change in solar cell’s output. Geometric analysis and experiments are performed to investigate the effectiveness of the proposed method. The results provide a new structural insight for acceleration sensors. In order to assess the efficacy of the proposed approach, geometric analysis and experiments are conducted. The resonance frequency of an acceleration measurement device using an auxetic structure is approximately 100Hz, while for a device using a non-auxetic structure, it is about 40Hz, both reaching the maximum wavelength variation. The results give potential paths for future study as well as new structural insights for acceleration sensors.
