Experimental Phase Shift in Rotating Piezoelectric Device

This experiment used a piezoelectric crystal—materials that can turn mechanical pressure into electrical signals—to explore how motion affects time. Normally, piezoelectric devices need electricity to work, but here, no electricity was applied. Instead, the crystal was simply rotated.

Surprisingly, the crystal started producing a clear 50 Hz electrical signal all on its own, and more importantly, that signal began to slowly drift in phase, meaning its timing was shifting little by little—like a second hand running slightly ahead or behind on a clock. This shift wasn’t random; it matched the speed of rotation, showing that the motion itself was causing a change in the crystal’s internal behaviour.

This lines up perfectly with how piezoelectric materials work: when they're squeezed, stretched, or rotated, their structure changes in ways that can generate electricity. The experiment showed that rotation was enough to create internal stresses in the crystal that made it behave like a tiny self-powered clock—one whose timing was subtly altered just by being spun.

These findings support a new physics idea called Extended Classical Mechanics (ECM), which says that motion—especially acceleration—can directly affect how time flows inside matter. The phase drift we saw in the experiment is like a fingerprint of this effect. So in simple terms: spinning the crystal made it create its own voltage and shift its timing, proving that motion can affect time in a measurable, physical way—without needing relativity or space travel.
