Scientists at the University of Guelph in Canada have developed a slime that produces electricity when squeezed. Although still in the prototype phase and undergoing early testing, the invention is already receiving praise from its creators. The findings were reported in a scientific article in the journal Science Direct.
The Canadian Light Source, the research facility involved in the study, explained that the slime consists of 90% water, along with oleic acid (found in olive oil) and amino acids. This combination makes the material safe to handle and suitable for direct contact with skin.
Biocompatible Piezoelectric Slime Generates Electricity Under Pressure
The slime developed by the researchers exhibits a piezoelectric effect, allowing it to produce electrical charges when compressed. “Many materials with this property exist, but most are not biologically based or fully biocompatible,” said Erica Pensini, the lead scientist on the project, in an interview with CTV.
In a CBC interview, Erica explained that energy-generating materials have dipoles, acting like “tiny batteries” with two poles. In most materials, these dipoles are misaligned, preventing electricity generation. The researchers found a way to align the molecules so compression generates energy.
Prototype Slime Shows Promise for Clean Energy and Healing Applications
Erica’s team believes the prototype could provide clean energy and support wound healing. “I apply the material to my hands. Ideally, it could enhance the body’s regeneration, since piezoelectricity plays a key role in many biological processes,” Erica said.
The practical uses of electric slime are still being explored, but Erica’s team sees its potential for generating energy from floors, enhancing robotic skin, or tracking movement in shoe soles.
Although it’s too early to know when—or if—this material will become part of everyday life, the potential applications are undeniably exciting.
