Glycine as an indirect structural inducer enhances silk fibroin piezoelectric performance for facial micromotion tracking during sleep
The study developed a fully green bioelectronic piezoelectric patch using silk fibroin with glycine as a structural inducer, which improved β-sheet content and piezoelectric performance. The patch enabled dual-channel wireless monitoring of rapid eye movements and nasal flaring during sleep with high conformability and sensitivity.

Frequently Asked Questions
What is the main innovation of this silk fibroin patch?▼
The patch uses glycine to enhance the piezoelectric properties of silk fibroin, making it soft, ultrathin, and biocompatible for unobtrusive sleep monitoring.
What facial movements can this patch track during sleep?▼
It can track rapid eye movements and nasal flaring in real-time via a wireless dual-channel system.
Is this patch safe for human skin?▼
Yes, it is made from fully biocompatible natural biomaterials (silk fibroin) and designed to be soft and conformable to skin.
What are the limitations of this study?▼
The abstract does not report human trial data or long-term durability testing, so real-world effectiveness remains to be validated.
