Bio-cards are inspirational cards describing a functional principle for a biological phenomena.

A bio-card should include the following information:
- A title describing the biological organism and the desired phenomena, e.g. Woodpecker pecking. It is an advantage to also mention the Latin name of the organism to allow for easy further information search.
- A picture or drawing of the organism - pre-ferably in action.
- A description of the phenomena using biology terminology.
- A description of the interesting principle applied in the phenomena formulated in functional engineering terms.
- A simplified drawing describing the principle

Each bio-card represents a conceptual idea and is used to generate design proposals.
