Emerald copper FTW 💚💎🧡
We can get a #piezoelectricity versus #pyroelectricity battle for the ages! It's * #ELECTRIC * ;P

Pressure or fire, heating things up to get zappadelic, gotta love that.

Better yet:
"As mentioned in the introduction, there is a profound relationship between pyro and piezo sensors: Every pyroelectric crystal is also a piezoelectric crystal (but not vice versa)."
Heating leads to expansion of the crystal lattice, and a measurable electric voltage.

(After the last two days seeing mass vote stuffing tampering attempts, they're auditing preliminary results, so please rope in new folks to vote for this little toxic pyro guy instead! 🍀 Thank you for voting!)

"Chunky gold nuggets tend to form far underground along fracture lines that run through quartz, but the reason why has never been nailed down."

Earthquakes May Forge Large Gold Nuggets

Scientists propose that large chunks of gold could form from earthquakes’ pressure

The new study, published on Monday in Nature Geoscience, suggests that the geological stress caused by earthquakes might activate a peculiar geochemical property of quartzes called “piezoelectricity”—and that that property makes the formation of larger gold nuggets possible.

‘Flutter instability’ is the aerodynamic phenomenon when a flag flaps in the wind. Flapping of flags has also been studied in the context of small devices called piezoelectric generators which can convert the mechanical energy of a flag's flapping into electrical energy.
