Unraveling the viscosity-mediated coupling effect in biomimetic hair sensor arrays

A dedicated microfabricated chip consisting of artificial hair sensors was realized and used to controllably and reliably investigate viscous coupling between the hair sensors. The experimental results confirm the presence of coupling effects between hair sensors when placed too close to each other. The results present significant insights in optimal array arrangements for high spatial resolution by preservation of the hair-sensors uncoupled (individual) responses.
