Limerick Researchers Make Green Energy Breakthrough with Amino Acid-Powered Crystals
Scientists at the University of Limerick (UL) have developed a revolutionary technique to grow organic crystals that could revolutionize the way we generate electricity. This innovative method utilizes amino acids, the building blocks of proteins found naturally in our bodies, to create piezoelectrics – materials capable of generating a voltage when subjected to pressure.
"The versatile moulding technique that we have developed is a low-cost, low-temperature growth method, that opens the path to phase in biomolecular piezoelectrics as high-performance, eco-friendly alternatives to currently used ceramics," explained Krishna Hari, the lead author and PhD student behind the project.
This route could usher in a new era of sustainable electronics, free from the environmental hazards posed by lead, a common ingredient in conventional piezoelectrics.
"I am excited to see if this takes off as a methodology for other people working in sustainable piezoelectrics.
There are EU regulations around the use of lead, but piezoelectrics are one of the last remaining mainstream technologies allowed to contain this substance because there is no high-performance alternative,” said Associate Professor Sarah Guerin, who received a prestigious European Research Council (ERC) starting grant for the "Pb-FREE: Piezoelectric Biomolecules for Lead-Free, Reliable, Eco-Friendly Electronics" project.
Previous research by Guerin’s team utilized predictive computer models to identify how much electricity various biological materials could generate under pressure. Importantly, the winning amino acids generate ample voltage for applications in consumer electronics and medical devices.
Think of a tiny disc pressed between your fingers; as it’s squeezed, it generates a voltage that can be amplified and used to charge your phone or power a medical sensor.
The UL team’s breakthrough lies in their ability to shape these piezoelectric crystals into custom designs using silicon molds, opening possibilities for a wide range of devices – from medical implants to car sensors.
The implications are vast. Every year, approximately 4,000 tons of electronics containing lead-based piezoelectrics end up in landfills. This research offers a hope to move away
from these harmful materials and towards a more sustainable future.
