Summary
New stretchable dry adhesives (SDAs) ensure conformal skin contact for high-quality biosignal acquisition. These non-hygroscopic adhesives enable advanced wearable health monitoring devices.
Area of Science:
- Materials Science
- Biomedical Engineering
- Wearable Technology
Background:
- Conformal skin-electrode contact is essential for high-fidelity multimodal biosignal acquisition from the skin.
- Existing stretchable dry adhesives (SDAs) face limitations due to poor stretchability and high water absorption.
Purpose of the Study:
- To develop highly stretchable, non-hygroscopic, and biocompatible SDAs.
- To enhance the performance of wearable biosignal monitoring devices.
Main Methods:
- Synergistic formulation of tannic acid and polyol compounds for SDAs.
- Integration of SDAs with stretchable transparent electrodes (STEs).
- Characterization of mechanical properties, adhesion, and performance in a wearable sleep monitoring device.
Main Results:
- Developed SDAs exhibit high crack onset strain (≥50%) and strong adhesion (>0.7 N cm⁻¹).
- The SDA/STE bilayer creates conformal interfaces for efficient biosignal acquisition.
- Wearable device performance for sleep stage analysis is comparable to clinical polysomnography.
Conclusions:
- The novel SDAs provide stable, conformal skin-electrode contact, crucial for biosignal acquisition.
- These ultrathin, transparent, and lightweight electrodes pave the way for commercializing user-friendly wearable health monitors.
