Electromagnetic Sensing Techniques for Monitoring Atopic Dermatitis-Current Practices and Possible Advancements: A...

Area of Science:

• Dermatology
• Biomedical Engineering
• Digital Health

Background:

• Atopic dermatitis (AD) affects nearly 20% of children and adolescents globally.
• Current AD monitoring relies on subjective clinical visual examinations.
• In-person assessments are restrictive for patients with limited access to healthcare.

Purpose of the Study:

• To review the evolution of atopic dermatitis monitoring techniques.
• To explore current clinical practices and emerging digital health solutions.
• To discuss future technologies for empirical AD assessment.

Main Methods:

• Discussion of traditional methods: biopsy, tape stripping, and blood serum analysis.
• Highlighting non-invasive digital methods assessing biomarkers: AD-TEWL, skin permittivity, elasticity, and pruritus.
• Showcasing future technologies: radio frequency reflectometry and optical spectroscopy.

Main Results:

• Traditional methods have limitations in objectivity and accessibility.
• Digital sensing offers potential for accurate, empirical AD evaluation.
• Emerging technologies promise improved, accessible patient monitoring.

Conclusions:

• Digital sensing technologies are crucial for developing next-generation e-health devices for AD.
• Further research is needed to refine current techniques and implement new ones.
• An improved AD monitoring device can facilitate earlier and more accurate medical diagnosis.
