Scientists Crack 250-Year-Old Mystery of Static Electricity

Quick Summary

• Static electricity, termed “contact electrification” by scientists, has puzzled researchers for centuries despite its everyday familiarity.
• Recent findings by physicist Scott Waitukaitis adn his colleague Juan-Carlos Sobarzo reveal that materials “remember” previous contacts, altering their charge behavior over time.
• Experimentation using a precise setup uncovered that silicone polymer (PDMS) samples displayed systematic changes in charge depending on their contact history.
• Key findings suggest smoother surfaces from repeated contacts influence negative charging and hint at flexoelectricity-charging via bending-as a possible explanation.
• The study challenges long-standing assumptions about contact electrification and opens new paths for understanding a phenomenon essential to electromagnetic force yet not fully explained.
