摘要

本文对一种新型微悬臂梁红外传感器进行了分析研究。采用六边形结构增加了吸收的能量,并且由于采用六边形坐标,有利于后续的成像处理。填充系数也是该设计中改进最多的属性之一。双材料微悬臂梁作为一种机械传感器,它基于所使用材料的两次热膨胀之间的不匹配而偏转。最大偏转进行了分析和计算NETDTF(噪声等效温差)计算低至2.5 mK,这证明了所提出的传感器的良好性能。

Hexagonal shaped microcantilever based IR imaging sensor
This paper is an analytical study for a new design microcantilever based IR (Infra Red) sensor. Using hexagonal structure increases energy absorbed, and is useful for the imaging processing after that due to using hexagonal coordinates. Fill factor is also one of the most properties improved in this design. Bimaterial microcantilever is used as a mechanical sensor which is deflected based on the mismatch between the two thermal expansions for the materials used. Maximizing deflection is analyzed and computed NETDTF (Noise Equivalent Temperature Difference) calculated as low as 2.5 mK which proof the good performance of the proposed sensor.
