The Takeaway
Alanine is a simple biological building block found in proteins throughout your body. Researchers have grown this amino acid into organic-inorganic crystals that exhibit a massive piezoelectric effect. This means the crystal can turn mechanical pressure into electricity better than lithium niobate, the current industry standard. These biological crystals are easier to grow and much more environmentally friendly than traditional electronic materials. They could lead to a new generation of biodegradable sensors and wearable health monitors. This discovery proves that nature's own chemistry can beat our most advanced lab-grown technology.
From the abstract
We synthesized six hybrid organic-inorganic composite biomaterials, utilizing alanine-one of the most important amino acids-as a key building block. Our research focused on the physicochemical properties of Pyridyl-Alanine based crystals. These alanine-derived materials were characterized using single-crystal X-ray diraction, thermogravimetric analysis, IR and Raman spectroscopy, and piezoresponse force microscopy. Remarkably, the studied biomaterials exhibited a piezoelectric modulus surpassing
