Dynamic pressure mapping of infant cervical spines using a wearable magnetoelastic patch

Area of Science:

• Biomedical Engineering
• Materials Science
• Pediatric Healthcare

Background:

• Infant cervical spines are vulnerable due to immaturity and anatomical factors, making them prone to fractures.
• Current methods for monitoring infant cervical spine biomechanics are limited, hindering early injury detection and prevention.

Purpose of the Study:

• To develop a novel kirigami-inspired soft magnetoelastic patch for continuous, dynamic monitoring of biomechanical pressure on the infant cervical spine.
• To enable early diagnosis and prevention of cervical spine injuries in infants through precise pressure quantification.

Main Methods:

• Fabrication of a biocompatible, waterproof magnetoelastic patch with a skin-matched Young's modulus (108.2 kPa).
• Integration of a kirigami structure to enhance patch permeability, stretchability, and scalability.
• Utilization of machine-learning algorithms to quantitatively decode cervical spine pressure data from the patch.

Main Results:

• The patch demonstrated a high signal-to-noise ratio (34.05 dB) for reliable data acquisition.
• The combined system achieved up to 99.2% accuracy in measuring and decoding cervical spine pressure.
• The kirigami design facilitated enhanced material properties for wearable applications.

Conclusions:

• The kirigami-inspired soft magnetoelastic patch provides a safe, comfortable, real-time, and non-invasive method for infant cervical spine monitoring.
• This innovative system offers precise and reliable data for the early detection and management of infant cervical spine disorders.
• The developed technology represents a significant advancement in pediatric injury prevention and care.
