Have you ever wondered if the simple building blocks of life could one day power our wearable electronics? Glycine, the simplest amino acid found in our bodies, has a superpower in its β-phase form: it is highly piezoelectric, meaning it can convert mechanical pressure into electricity. However, this phase of glycine is unstable, usually transforming into a non-piezoelectric α-phase before we can ever use it in a device. We wanted to see if we could trap this elusive phase in tiny spaces to keep it stable.
