Abstract

This paper reports a cantilever with comb structure, inspired by a bristled wing of thrips which acts as a continuous membrane wing because of the effects of low Reynolds numbers. The comb structures are formed at the edges of the cantilever and its surrounding frame. When differential pressure is applied to the cantilever, both comb structures act as airflow suppression through the gap. The leakage of the fabricated comb cantilever was smaller than the normal cantilever due to the overlapping area of the combs, even the gap area was twice larger. The proposed structure will be utilized as a high sensitive barometric pressure change detector.
