Bio-inspired cooling technology

This topic provides a relevant example of biomimicry and nanotechnology applications in cooling technology, which can be used as illustrative context in GS3 science and technology answers.

Notes

Scientists identified previously unknown hair-like structures on beagles' tongues that facilitate rapid saliva spread and evaporation for thermoregulation.
BioCCS is a new material inspired by these biological structures for cooling electronic devices.
The material surface features microscopic grooves designed to enhance liquid spreading.
Nanowires integrated within the grooves function to weaken intermolecular bonds in water, thereby accelerating the evaporation process.

Part of a longer story

This is day 1 of 2 in Development of Bio-inspired Cooling Technologies, which has been running since 2 August 2026. Reading it whole is usually worth more than reading today alone — the exam asks how something developed.
