Biomimetic Hair Sensor Arrays: From Inspiration To Implementation

In this work, we report on the successful implementation of highly sensitive artificial hair-based flow-sensor arrays for sensing low-frequency air flows. Artificial hair sensors are bio-inspired from crickets’ cercal filiform hairs, one of nature’s best in sensing small air flows. The presented artificial hair sensor arrays aim for sensing performances on a par with the actual insects by means of model-based design optimizations and are fabricated using advanced MEMS technologies.
