摘要：

In this paper, strain amplification of dome shape structure inspired by campaniform sensillum was investigated with the aim of proving that besides a hole that locally amplifies the strain, the dome shape structure also plays an important role in the sensing mechanism. Acting as a second mechanical signal amplifier, the concentrated strain is further amplified. Our simulation result showed that equivalent edge displacement Delta L induced by the concentrated strain was further amplified in vertical direction Delta h, with the gain value of 50 before it becomes higher and then will be maintained at a gain value of 70. However dome structure introduces a nonlinearity which was demonstrated when the structure loses its stability as the applied load exceeds the critical value of buckling. The biomimetic structure has a potential application as pre-transduction signal pre-amplifier in strain sensing devices, especially when miniaturization is concerned. Hence, before mechanical signal is transduced into electrical signal, it is being concentrated and amplified by the bio-inspired structure.
