The energy that is being harvested as part of this research is being generated by squeezing amino acid molecules, the building blocks of proteins that exist in the human body.

Piezoelectricity, which translates from Greek to mean pressing electricity, usually found in ceramics or polymers, is also present in human biomolecules.

The research team from the Actuate Lab in the Department of Chemical Sciences and Bernal Institute at UL has previously utilized predictive computer models that allow them to identify how much electricity a biological material will generate when you squeeze it—making this material suitable to power sensors in consumer electronics and medical devices.
