Dog’s tongue inspires new cooling tech for electronics, Pg15

Key Highlights:

• Scientists have developed a new cooling material named BioCCS.
• This innovation was inspired by previously unknown hair-like structures found on beagle dog tongues.
• These structures on dog tongues facilitate rapid saliva spread and evaporation, aiding in the animal's cooling process.
• BioCCS incorporates microscopic grooves for liquid spreading and nanowires to enhance water evaporation.

Detailed Insights:

• Dogs primarily regulate their body temperature through panting, which involves the evaporation of moisture from their tongues, mouths, and respiratory tracts.
• The newly identified hair-like structures on beagle tongues play a crucial role in optimizing this natural evaporative cooling by ensuring efficient distribution of saliva.
• The engineered material, BioCCS, replicates this biological efficiency by utilizing a surface with microscopic grooves to spread liquid rapidly.
• Within these grooves, nanowires are integrated to weaken the bonds between water molecules, thereby promoting easier and faster evaporation.
• This development is an example of biomimicry, where solutions to human problems are derived from studying and imitating natural designs and processes.
• Evaporative cooling is a natural phenomenon where heat is absorbed from the surrounding environment when liquid water transforms into vapor.

Scientific/Technical Concepts Involved:

• BioCCS: A novel material designed for efficient cooling, drawing inspiration from the evaporative cooling mechanism observed in dog tongues.
• Biomimicry: An innovative approach that seeks sustainable solutions to human challenges by emulating nature's time-tested patterns and strategies.
• Evaporative Cooling: A physical process where the change of state from liquid to gas absorbs latent heat from the surroundings, resulting in a cooling effect.
