The rough, waxy texture on the surface of the lotus leaf prevents water from penetrating the exterior of the leaf. Interestingly, the surface of the lotus leaf is not solid. Instead, a hydrophobic coating on the leaf creates a web-like barrier that allows moisture to rest on top rather than penetrating the leaf. The advanced HydraShield®2 system used in Starkey hearing aids mechanically mimics the lotus effect. The nano-coating keeps moisture and debris (like ...
