The actuator perhaps but the wiggling thing attached to it that moves the air? I don't think that's solid state? If it were you could even call a fan solid state.

On a macro scale it is solid state. Ultimately everything is vibrating when you look close enough.

The piezo is a single piece while a fan has at least two.
