Full title and description

STB VDI 6221 Blatt-1 2013-09 — "Bionik / Biomimetics - Biomimetic surfaces". Guidance for product and technology developers on designing and applying biologically inspired surface solutions (e.g., riblet drag-reduction and Lotus Effect® self‑cleaning) to technical surfaces and boundary‑layer functionalizations.

Abstract

This guideline defines the concept, examples, and development basis for biomimetic surfaces. It introduces terms and definitions, presents characteristic surface systems inspired by biology, and sets out criteria and a process framework to help engineers identify, evaluate and apply biological principles to surface design for improved functionality (drag reduction, self‑cleaning, wetting control, etc.).

Scope

Provides recommendations and a methodological basis for developers and engineers who want to transfer biological surface principles into technical products. The guideline covers identification of relevant biological effects, illustrative examples of biomimetic surface systems, foundational process steps for development, and criteria for assessing applicability and performance of surface functionalizations across sectors such as transport, marine, automotive, aerospace, textiles and coatings.

Key topics and requirements

• Definitions and terminology for biomimetic surfaces and related concepts.
• Illustrative examples of biomimetic surface systems (e.g., riblet effect, Lotus Effect® and other boundary‑layer functionalizations).
• Practical process framework: identifying biological models, abstraction of principles, technical translation and evaluation criteria.
• Criteria for assessing feasibility, functionality and energy/efficiency potential when applying biomimetic surface solutions.
• Normative references and bibliography to related biomimetics standards and ISO terminology/methodology documents.

Typical use and users

Used by product designers, R&D engineers, surface and coatings specialists, aerodynamicists/hydrodynamicists, materials scientists, and innovation teams in automotive, aerospace, marine, consumer products and industrial equipment who seek to improve surface functionality (drag reduction, self‑cleaning, anti‑fouling, wettability control) through biologically inspired design.
