That's a neat hook—dragons as natural biosensors. We could model a patch that tracks skin temp, pulse, and skin conductance, then uses an algorithm to infer mood states and adjust lighting or haptic feedback. The key is mapping those mythic “senses” to measurable physiological markers and ensuring the data is used to promote calm or alertness. Do you have a specific emotional trigger in mind, like stress or joy, that you want the device to respond to?
