Summary
Continuous manufacturing of glycine piezoelectric biocrystal films is now feasible. This polymer-directed crystallization method enables large-scale production of biocompatible piezoelectric devices for high-throughput applications.
Area of Science:
- Materials Science
- Biotechnology
- Crystallography
Background:
- Glycine is a biocompatible piezoelectric crystal with potential for device applications.
- Previous methods limited large-scale glycine film production.
