Acceleration Sensor Based on Mesopiezophotonic Effect of Mirror Structure Triply-Periodic Photonic Crystal*
摘要
Abstract
This paper employs mesoscopic calender effect of mirror Heterotrimer periodic photonic crystal to design a new type of high-sensitivity acceleration sensor and it replaces the pressure-sensitive resistive film of traditional pie-zoresistive acceleration sensor. This acceleration sensor uses four-terminal fixed beam structure and effectively eliminates the off-axis effects. Futher it also has good stability and the measurable acceleration range is 0~137 gn at room temperature. Static analysis and modal analysis are tested by ANSYS software for the design of photonic crystal acceleration sensor. It can be seen that the sensor has a maximum value of strain in the root of the cantilever and the first modal frequency is different from other three modal frequencies, thus it can effectively reduce the cross-coupling. The photonic crystal is placed in the root of the cantilever to have a maximum sensitivity of the sensor. The accelerometer has a great advantage to apply to the aerospace and military fields.关键词
